The present invention relates to a power integration system, and describes a method for inputting and displaying information in a power integration system and an operator interface for the power integration system.

This application claims the priority of U.S. Provisional Patent Application 60 / 869,439, "A Distributed Energy Storage Management System," filed December 11, 2006, which is incorporated herein by reference; US Provisional Patent Application 60 / 915,347, "Plug-ln-Vehicle Management System," filed May 1, 2007, incorporated herein by reference; See, for example, US Patent Application No. 11 / 836,756, "Power Aggregation System for Distributed Electric Resources," filed August 9, 2007, by reference.

Transport systems that are highly dependent on fossil fuels are particularly carbon intensive. That is, the work of the physical unit carried out in the transport system usually releases significantly more CO ₂ into the atmosphere than the work of the same unit carried out electrically.

The power grid includes limited unique facilities for storing electrical energy. Electricity must be generated continuously to meet the uncertain demands that often cause excess generation (wasting energy) and sometimes underpowering (capacity generation).

Distributed electrical resources can be integrated to in principle provide an important resource for handling the problem. However, current power service infrastructure lacks the supply and flexibility required to integrate many small resources (eg, electric vehicle batteries) to meet medium and large power service needs. Single vehicle batteries are pointless when compared to the demands of a power grid. As electric vehicles become more prevalent and widespread, there is a need for a method of adjusting the vast number of electric vehicle batteries.

A low-level electrical and communication interface that enables charging and discharging of an electric vehicle to a grid is described in US Pat. No. 5,642,270, which is incorporated herein by reference, which is filed by Green et al. And entitled "Battery powered electric". vehicle and electrical supply system ". The aforementioned Green patent describes a two-way charging and communication system for grid-connected electric vehicles, but includes information processing requirements for a large number of mobile populations of electric vehicles, the complexity of vehicle owner payments (or compensation), and the grid operator. It does not address the complexity of assembling a mobile pool of electric vehicles with an integrated power resource that is robust enough to support a stable power service contract.

As used herein, “power service” refers to energy delivery as well as other incidental services including demand response, conditioning, spinning reserve, non-spinning reserve, energy imbalance, and similar products. As used herein, "aggregation" refers to the ability to control the flow of power into and out of a set of spatially distributed electrical resources for the purpose of providing larger scale power services. As used herein, "power grid operator" refers to the entity responsible for maintaining the operation and stability of the power grid with respect to the electrical control area. The power grid operator configures any combination of manual / human action / mediation and automation processes that control the generated signals in response to system sensors. The "control area operator" is an example of a power grid operator. As used herein, “control area” refers to the part included in the electrical grid with defined input and output ports. The net flow of power to this area must be equal to the sum of the power consumption in the area and the power output from the area (within some error tolerance).

As used herein, "power grid" refers to a power distribution system / network connecting power producers and power consumers. The network includes a safety device as part of any / all of generators, transformers, interconnects, switching stations, substations, feeders, and power transmission systems (i.e. bulk power) or power distribution systems (i.e. retail power). It may include. The example power integration system can be scaled up vertically for use in a neighborhood, city, sector, control area, or one of eight large interconnects (for example) of the North American Electric Reliability Council (NERC). In addition, the example system may scale horizontally for use in providing power services to multiple grid areas simultaneously.

As used herein, a "grid state" refers to the need for the approximate power flowing into and out of a section of a power grid, in response to one of a number of states, for example, supply changes, demand changes, accidents and failures, ramping events, etc. it means. These grid states usually manifest themselves as power quality events such as under or over voltage events and under or over frequency events.

As used herein, “power quality event” usually refers to signs of power grid instability, including voltage deviation and frequency deviation, and power quality events also indicate power quality delivered by the power grid, such as sub-cycle voltage spikes and harmonics.

As used herein, an “electrical resource” is usually an electrical entity that can be instructed to perform some or all of the following three (power acquisition (operation as load), power provision (power generation or operation as power source), and energy storage). Indicates. Examples may include battery / charger / inverter systems for electric or hybrid vehicles, storage of used but serviceable electric vehicle batteries, fixed energy storage, fuel cell generators, emergency generators, controllable loads, and the like.

"Electric vehicles" is used broadly here to refer to plug-in hybrid electric vehicles (PHEVs), in particular pure electric and hybrid electric vehicles such as vehicles having a large storage battery and connecting to a power grid to recharge the battery. More specifically, an electric vehicle means a vehicle that obtains some or all of its energy from the power grid for operation and other purposes. In addition, the electric vehicle has an energy storage system that can be configured with a battery, a capacitor, or the like or some combination thereof. The electric vehicle may or may not have the ability to return power to the electric grid.

Electric vehicle “energy storage systems” (batteries, supercapacitors and / or other energy storage devices) are used here as representative examples of electrical resources that are intermittently or permanently connected to a grid that may have dynamic input and output of power. Such a battery can function as a power source or a power load. Despite the recognizable trend of periodical connections (for example, an increase in the total number of vehicles connected to the grid at night; a decrease in the cumulative number of connected batteries as the morning commute begins), the set of integrated electric vehicle batteries A plurality of batteries can be a statistically stable resource. For large electric vehicle batteries, the connection tendency is predictable and these batteries become stable and reliable resources for the demands, so that the grid or part of the grid (such as an uninterrupted home) needs for increased or reduced power Should experience. Data integration and storage also enables power integration systems to predict connection behavior on a per-user basis.

Example system

1 illustrates an embodiment of a power integration system 100. Flow control center 102 includes one or more servers 106 that are communicatively connected to a network, such as a public / private mix, including the Internet 104, and that provide centralized power integration services. “Internet” 104 will be used herein as representative of several different kinds of communicable networks and network mixtures. Through a network such as the Internet 104, the flow control center 102 communicates with the grid operator 108, and with the remote resource 110, ie, the peripheral electrical resource 112 connected to the power grid 114. Maintain communication with the “termination” or “terminal” node / device of the power network. In one embodiment, a powerline communicator (PLC), such as including or consisting of an Ethernet-over-powerline bridge 120, is performed at a connection location to provide Internet communication with remote resources. The "last mile" (in this case, the last feet-eg, in the residence 124) runs through the same wire that connects each electrical resource 112 to the power grid 114. Therefore, each physical location of each electrical resource 112 is associated with a corresponding Ethernet-over-powerline bridge 120 (hereinafter referred to as “bridge”) at or near the same location as the electrical resource 112. . Each bridge 120 is generally connected to the place owner's Internet access point and will be described in more detail below. The communication medium from flow control center 102 to a connection location, such as residence 124, may take many forms, such as cable modem, DSL, satellite, optical communication, WiMax, and the like. In a variant, the electrical resources 112 are connected to the Internet by a different medium than the same powerline that connects them to the power grid 114. For example, a given electrical resource 112 may have its own radio capability to connect directly to the Internet and thereby to the flow control center 102.

The illustrated power integration system 100 electrical resource 112 may include a battery of an electric vehicle connected to the power grid 114 at a residence 124, a parking lot 126, or the like; Batteries in a repository 128, fuel cell generators, private dams, conventional power plants, and other resources that produce electricity and / or store electricity physically or electrically.

In one embodiment, each participating electrical resource 112 or group of local resources has a corresponding remote intelligent power flow (IPF) module 134. The centralized flow control center 102 manages the power integration system 100 by communicating with remote IPF modules 134 distributed among the electrical resources 112. The remote IPF module 134 may include providing a status of a remote resource to the flow control center 102; Controlling the amount, direction, and time at which power is transferred to or from the remote electrical resource 112; Power metering to or from the remote electrical resource 112; Changing conditions in the power grid 114 and providing safe measurements during power transfer; Activity records; And autonomous control of safe measurement and power transfer when communication with the flow control center 102 is interrupted. The remote IPF module 134 will be described in more detail below.

2 illustrates another embodiment of an electrical and communications connection to an electrical resource 112. In this embodiment, the electric vehicle 200 includes a battery bank 202 and an example remote IPF module 134. The electric vehicle 200 connects to a wall socket (wall connector) 204 of a conventional residence 124, which wall socket 204 is a peripheral edge of the power grid 114 connected through the residence power line 206. Represents.

In one embodiment, the power cord 208 between the electric vehicle 200 and the wall connection 204 may be comprised of conventional wires and insulators only for conducting AC power to and from the electric vehicle 200. . In FIG. 2, the location-specific connection location module 210 performs the function of a network access point—in this case, an Internet access point. The bridge 120 intervenes between the socket 204 and the network connection point to allow the power cord 208 to carry network communication between the electric vehicle 200 and the socket 204. With such bridge 120 and connection location module 210 in place within the connection location, other special wiring or physical media other than the conventional power cord 208 that provides a residential line current at a conventional voltage may be used in the electric vehicle 200. It is not necessary to communicate with the remote IPF module 134. Upstream of the connection location module 210, communication with the electric vehicle 200, and power are broken down into a power line 206 and an internet cable 104.

Alternatively, power cord 208 may have safety features not found in conventional power and extension cords. For example, the electrical plug 212 of the power cord 208 may provide electrical and electrical protection that prevents the remote IPF module 134 from exposing or conducting the male conductor of the power cord 208 when the conductor is exposed to the user. And / or mechanical protective components.

3 illustrates another embodiment of the connection location module 210 of FIG. 2 in more detail. In FIG. 3, electrical resource 112 has a combined remote IPF module 134 that includes a bridge 120. The power cord 208 also connects the electrical resource 112 to the power grid 114 and also to the connection location module 120 to communicate with the flow control server 106.

The connection location module 210 may in this case be different from the bridge 120 'connected to the network connection point 302, which includes components such as routers, switches, and / or modems that make a wired or wireless connection with the Internet 104. Include an example. In one embodiment, the power cord 208 between the two bridges 120, 120 ′ is replaced with a wireless Internet link such as a wireless transceiver in the remote IPF module 134 and a wireless router in the connection location module 210.

One example of a flow control center 102 may manage electrical resources 112 from a plurality of separate control regions 501 (eg, control regions 502, 504, 506). In one embodiment, this functionality is achieved by logically partitioning resources within the power integration system 100. For example, the control area 402 may be any number of control areas, control area “A” 502, control area “B” 504,. , Control area “n” 506, grid operation 116 then corresponds to corresponding control area operators 508, 510,. , 512 may be included.

For example, the first flow control center 102 manages control area A 502 and control area B 504, and the second flow control center 102 ′ manages control area n 506. . Similarly, corresponding control area operators 508, 510, 512 are serviced by the same flow control center 102 acting on each different control area.

Embodiment Flow Control Server

7 shows an embodiment server 106 of the flow control center 102. The embodiment shown in FIG. 7 is only one exemplary configuration for explanation. Embodiments of the flow control center 102 Many other configurations of the illustrated components or even other components that make up the server 106 are possible within the scope of the inventive concept. Such embodiment server 106 and flow control center 102 may be implemented in hardware, software, or a combination of hardware, software, firmware, and the like.

Embodiments The flow control server 106 may include a connection manager 702 that communicates with the electrical resource 112, a prediction engine 704 including a learning engine 706 and a statistics engine 708, a limit optimizer 710, And a grid interaction manager 712 that receives the grid control signal 714. The grid control signal 714 includes a power generation control signal, such as an automated generation control (AGC) signal. The flow control server 106 includes a web server 718, DB / information store 716, which provides a user interface to the electrical resource owner 408, the grid operator 404, and the electrical connection place owner 410; Contract manager 720, which negotiates contract terms with energy market 412, tracks weather, related news events, etc., predicts the behavior of large groups of electrical resources 112, monitors energy prices, contracts It further includes an information acquisition engine 414 that downloads information from the public / private DB 722 for negotiation.

Embodiment of the Flow Control Server

The connection manager 702 maintains a communication channel with each electrical resource 112 connected to the power integration system 100. That is, the connection manager 702 causes each electrical resource 112 to log on and communicate using the Internet Protocol (IP), for example if the network is the Internet 104. In other words, the electrical resource 112 calls home. That is, in one embodiment, they always initiate a connection with the server 106. This fact allows the embodiment IPF module 134 to overcome problems such as firewall, IP addressing, reliability, and the like.

For example, when an electrical resource 112 such as an electric vehicle 200 plugs in at home, the IPF module 134 may connect to a router in the home through a power line connection. The router will assign an address to the vehicle 200 (DHCP), and the vehicle 200 can be connected to the server 106 (there are no holes required for the firewall in this direction).

If the connection is terminated for any reason (including temporary downtime of the server), the IPF module 134 will call home again and recognize that it will connect to the next possible server resource.

The grid interaction manager 712 receives and interprets signals from the interface of the automatic grid controller 118 of the grid operator 404. In one embodiment, grid interaction manager 712 also generates a signal to send to automatic grid controller 118. The range of signals to be transmitted depends on the contract or agreement between the grid operator 404 and the embodiment power integration system 100. In one scenario, grid interaction manager 712 transmits information about the availability of integrated electrical resources to receive power from the grid or to power the grid. In another variation, the contract is such that the grid interaction manager 712 controls the grid 114 according to the limits embedded in the automatic grid controller 118 and according to the extent of control allowed by the contract. Send a control signal.

DB 716 stores all of the power integration system 100 related data including, for example, electrical resource logs, electrical connection information, per-vehicle energy metering data, resource owner preferences, account information, etc. for the electric vehicle 200. Can be.

Web server 718 provides a user interface to system stakeholders as described above. Such a user interface acts as a mechanism for the information to convey to the first user, but in some cases, the user interface obtains data such as preferences from the user. In one embodiment, web server 718 may also initiate a connection with participating electrical resource owner 408 to advertise a proposal to exchange power.

The bid / contract manager 720 interacts with the grid operator 404 and its associated energy market 412 to determine system availability, price, service level, and the like.

Information acquisition engine 414 communicates with public and private DBs 722 as described above to collect data related to the operation of power integration system 100.

Prediction engine 704 uses data store 716 to predict, for example, the behavior of electrical resources, such as when electrical resources 112 will connect and disconnect, global electrical resource availability, electrical system load, real-time energy prices, and the like. Use data from The prediction allows the power integration system 100 to more fully utilize the electrical resources 112 connected to the power grid 114. The learning engine 706 tracks, records, and processes the behavior of the actual electrical resource, for example by learning the behavior of the cross-sections or samples of the plurality of electrical resources 112. The statistics engine 708 applies various prediction techniques to resource behavior to recognize and predict trends.

In one embodiment, prediction engine 704 performs prediction through collaborative filtering. Prediction engine 704 may also perform user-specific prediction of one or more parameters, including, for example, connection-time, connection duration, charging state upon connection, and connection location. In order to perform the user-specific prediction, the prediction engine 704 obtains information such as historical data, connection time (year, month, day, holiday, etc.), charging status at connection, connection location, and the like. In one embodiment, time series prediction may be computed via a recurrent neural network, a dynamic Byesian network, or other derived graphical model.

In one scenario, for one user separated from the grid 114, the prediction engine 704 may predict (and assign probability / probability) the next connection time, the state of charge on connection, and the connection location. . Once the resource 112 is connected, the connection time, the on-charge state of connection, and the connection location are additional inputs to improve the prediction of the connection duration. This prediction helps guide the prediction of overall system availability along with determining a more accurate cost function for resource allocation.

Building a parameterized predictive model for each particular user is not always adjustable in time and space. Therefore, in one embodiment, rather than using one model for each user in system 100, prediction engine 704 builds a reduced set of models, where each model in the reduced set is It is used to predict the behavior of many users. To determine how to group similar users for model generation and assignment, the system 100 may characterize each user such as the number of specific connections / disconnections per day, typical connection time, average connection duration, average charge state at connection, and so on. In addition, dimension reduction algorithms, such as Principal Components Analysis and Random Projection, can be used to create clusters of users in the entire computed feature space or in some reduced feature spaces. Once prediction engine 704 assigns users to the cluster, aggregate data from all users in the cluster is used to generate a prediction model that will be used for prediction of each user in the cluster. In one embodiment, the cluster assignment procedure is varied to optimize the system 100 in speed (less clusters), accuracy (more clusters), or a combination of both.

This embodiment clustering technique has several benefits. First, it enables a reduced set of models, reducing model parameters and reducing computing time for making predictions. This also reduces the storage of model parameters. Second, by identifying the characteristics (or characteristics) of the new user for the system 100, the new user can be assigned to an existing user cluster with similar characteristics, and the cluster model is a cluster model created from the extensive data of the existing user. Affects the performance history of similar users, making faster predictions for new users. Of course, over time, individual users are reassigned to new clusters whose behavior changes and better fits their behavior.

The limit optimizer 710 combines the information of the prediction engine 704, the data store 716, and the contract manager 720 to generate a resource control signal to satisfy the system limit. For example, the limit optimizer 710 may charge the battery bank 202 at any charge rate and later discharge the battery bank 202 for power upload to the power grid 114 at any upload rate. 200 may signal: the power transfer rate and the time schedule of the power transfer are optimized for the tracked individual connection and disconnection behavior of a particular electric vehicle 200, and the daily power supply and demand of the power grid 114 Optimized for the "breathing cycle".

In one embodiment, the limit optimizer 710 plays a decisive role in converting the grid control signal 714 or information source 414 into a vehicle control signal, which is mediated by the connection manager 702. Mapping grid control signals 714 from grid operator 404 or information source 414 to control signals sent to each particular electrical resource 112 in system 100 is an example of a particular constraint optimization problem. .

Each resource 112 has a hard or soft associated limit. Examples of resource limits include: owner's price sensitivity, vehicle charging state (e.g., no burden on grid 114 if vehicle 200 is fully charged); Predicted amount of time until separation from 100, owner's sensitivity to state of charge versus income, electrical limits of resource 114, manual charge override by resource owner 408, and the like. . Restrictions on specific resources 112 may be used to assign costs to the activation of each particular action of the resource. For example, the low energy resources stored in storage system 202 have a low cost with respect to charging operations but high costs for power generation operations. The fully charged resource 112, which is expected to be available for 10 hours, will have a lower cost for power generation operations than the fully charged resource 112, which is expected to be separated in the next 15 minutes, which is the owner of the non-full resource. Indicates a negative result of delivering to a customer.

The following converts one generation signal 714 into a vehicle control signal that includes a system operating level (e.g., here -10 megawatts to +10 megawatts, where + represents loading and-represents power generation). One scenario example. It is to be noted that the actual system operating level is always known because the system 100 can measure the actual power flow within each resource 112.

In this embodiment, assuming the initial system operating level is 0 megawatts, no resources are activated (takes power from the grid) and the negotiated integrated service contract level for the next time is ± 5 megawatts.

In this embodiment, the embodiment power integration system 100 maintains three lists of available resources 112. The first list contains resources 112 that can be charged (loaded) activated in priority order. There is a second list of resources 112 that are first discharged (generated) in order. Each resource 112 in these lists (eg all resources 112 can be located in both lists) has an associated cost. The priority order of the list is directly related to the cost (ie, the list is sorted from lowest to highest cost). Assigning a cost value to each resource 112 is important because it allows you to compare two actions that yield similar results for system operation. For example, adding one unit of charging unit (load, taking power from the grid) to the system is equivalent to removing one unit of power generation. In order to perform any operation that increases or decreases the system output, there may be a plurality of operation choices, and in one embodiment, the system 100 selects the lowest cost operation. The third list of resources 112 includes resources with strict limits. For example, a resource whose system was overridden by its owner to force charging would be placed on a third list of static resources.

At time "1", the grid-operator-request operating level is changed to +2 megawatts. The system initiates charging of the first 'n' resources in the list, where 'n' is the number of resources for which the additional load is expected to be 2 megawatts. After the resource is activated, the result of the activation is monitored to determine the actual result of the action. If more than 2 megawatts of load is active, the system will disable charging in reverse priority order to maintain system operation within the tolerance specified by the contract.

From time "1" to time "2", the requested operating level does not change at 2 megawatts. However, the behavior of some electrical resources is not fixed. For example, some vehicles 200 that are part of a two megawatt system operation are either fully charged (charged state = 100%) or disconnected from the system 100. The other vehicle 200 is connected to the system 100 and immediately requests charging. All of these actions result in a change in the operating level of the power integration system 100. Therefore, system 100 continuously monitors the system operating level and activates or deactivates resource 112 to maintain the operating level within the tolerance specified by the contract.

At time "2", the grid-operator-request operating level decreases to -1 megawatts. The system considers the list of available resources and selects the lowest cost set of resources that achieves a system operating level of -1 megawatts. In particular, the system first moves through the list in turn to compare the charge disablement cost to the power generation execution cost, and activate the lowest cost resource at each time step. Once the operating level reaches -1 megawatts, the system 100 continues to monitor the actual operating level, requiring activation of additional resources 112 to maintain the operating level within the tolerance specified by the contract. Find the deviation.

In one embodiment, the embodiment cost mechanism generally has an impact on the environment and fossil fuel resources, i.e., the marginal impact of charging or power generation (vehicle 200 to grid 114) on the "carbon footprint". To determine this, information about the real-time grid power generation mixture is given. Embodiment system 100 also allows for optimization of any cost measurement or some weighted combination. System 100 may optimize performance indexes, including, for example, combinations that maximize economic value, minimize environmental impact, and the like.

In one embodiment, system 100 also uses cost as a time variable. For example, if the system 100 schedules charging a discharged pack during an upcoming time window, the system 100 can predict its predicted cost profile while charging, allowing the system to be adaptively further optimized. That is, in some circumstances, it is understood that system 100 will have high-capacity generation resources until a certain future time.

The plurality of components of the flow control server 106 constitute a scheduling system having a plurality of functions and components:

데이터 통합(실시간 데이터를 모으고 이력 데이터를 저장함);

Data integration (collecting real-time data and storing historical data);

실시간 데이터, 이력 데이터 등을 입력하고 리소스 가용성 예측을 출력하는 예측 엔진(704)을 통한 예측; 및

Prediction through a prediction engine 704 that inputs real-time data, historical data, and the like and outputs resource availability predictions; And

리소스 가용성 예측, 그리드 운영자(404)로부터의 명령 신호와 같은 제한, 사용자 선호, 날씨 조건 등에 의거한 최적화.

Optimization based on resource availability predictions, restrictions such as command signals from grid operator 404, user preferences, weather conditions, and the like.

The optimization may take the form of a resource control plan that optimizes the desired metering.

The scheduling function may enable a number of useful energy services, such as:

빠른 반응 서비스와 빠른 조절과 같은 보조 서비스;

Auxiliary services such as quick response service and quick conditioning;

갑작스러운, 예측 가능한, 또는 예기치않은 그리드 불균형에 대하여 보상하는 에너지;

루틴하고 불안정한 요구에 대응;

Responding to routine and unstable needs;

재생 에너지 소스의 안정화(예를 들어, 풍력 발전 보완).

Stabilization of renewable energy sources (eg wind power supplementation).

Embodiments The power integration system 100 integrates and controls the loads presented by many charging / uploading electric vehicles 200 to provide power services (auxiliary energy services) such as regulating and pure reserves. Therefore, it is possible to meet the call time requirement of grid operator 404 by summing up a plurality of electrical resources 112. For example, twelve operating loads of 5 kW may be disabled to provide 60 kW of pure reserve for each hour. However, at most loads can be disabled for 30 minutes and with a minimum call time of 2 hours, the load can be disabled continuously (three at a time) to provide a reserve of 15 kW for 2 hours. Of course, more complex interleaving of individual electrical resources by the power integration system 100 is possible.

In order for the utility (or power distribution company) to maximize distribution efficiency, the utility needs to minimize reaction power flow. In general, there are a number of methods that are used to minimize reaction power flow by including switching inductors or capacitor banks in a power distribution system to change power factors within different parts of the system. In order to effectively manage and control this dynamic Volt-Amperes Reactive (VAR) support, this must be done in a location-aware manner. In one embodiment, the power integration system 100 includes power-factor correction circuitry disposed in the electric vehicle 200 with the remote IPF module 134 embodiment, thereby enabling such services. In particular, the electric vehicle 200 may have a capacitor (or inductor) that can be dynamically connected to the grid regardless of whether the electric vehicle 200 is charging, power delivery, or doing nothing. This service can then be sold to utilities for distribution level dynamic VAR support. The power integration system 100 may use a distributed remote IPF module 134 that senses the need for VAR support in a distributed manner and also takes the action of providing VAR support without grid operator 404 intervention.

Ethernet physical layer interface 822 provides electrical, mechanical, and procedural interfaces to the transmission medium—that is, in one embodiment using Ethernet-over-powerline bridge 120. In a variation, a wireless or other communication channel with the Internet 104 is used instead of the Ethernet-over-powerline bridge 120.

Embodiment of Remote IPF Module Operation

Continuing with the description of the electric vehicle 200 representing the electric resource 112, the remote IPF module 134 is a flow control server for a period of time while the electric vehicle 200 is parked and connected to the grid 114. A connection is initiated to 106, self-registering, and waits for a signal from the flow control server 106 to instruct the remote IPF module 134 to regulate the flow of power to the electric vehicle 200. This signal is communicated to the vehicle computer 802 via a data interface, which may be any suitable interface including an RS-232 interface 818 or a CANbus interface 820. The vehicle computer 802, depending on the signal received from the flow control server 106, causes the inverter / charger 804 to charge the battery bank 202 of the vehicle or upload and discharge the battery bank 202 to the grid 114. To control.

Periodically, the remote IPF module 134 sends information about the energy flow to the flow control server 106. If, when the electric vehicle 200 is connected to the grid 114, and there is no communication path to the flow control server 106 (that is, the location is not properly equipped or a network failure occurs), the electric vehicle 200 May follow a pre-programmed or learned behavior of offline operation, for example, stored as a set of instructions in non-volatile memory 816. In this case, the energy transaction may also be cached in nonvolatile memory 816 for later transfer to flow control server 106.

During the period in which the electric vehicle 200 operates such as transportation, the remote IPF module 134 receives passively and logs selected vehicle operation data for later analysis and use. Remote IPF module 134 may send the data to flow control server 106 when a communication channel becomes available.

Example Power Flow Meter

Power is the energy consumption rate per time interval. Power represents the amount of energy transmitted over a period of time, so the unit of power is the amount of energy per unit time. Exemplary electricity meter 824 measures bi-directional flow power for a given electrical resource 112-for example, power from grid 114 to electric vehicle 200 or from electric vehicle 200 to grid 114. do. In one embodiment, the remote IPF module 134 retrieves the value from the electricity meter 824 to ensure accurate transactions with the central flow control server 106 even if the connection to the server is temporarily suspended or the server itself is unavailable. Can be cached locally.

Example meter 824 allows features including the following for the entire system in example power integration system 100 in conjunction with other components of remote IPF module 134:

Mobile resource detector

Exemplary power integration system 100 also includes various techniques for determining the electrical network location of mobile electrical resources 112, such as plug-in electric vehicles 200. The electric vehicle 200 may be connected to the grid 114 of a plurality of locations and accurate control and trading of energy exchange may be enabled by specific knowledge of the charging location.

Some example techniques for determining an electric vehicle charging location include:

위치에 대한 고유 식별자를 질의(유,무선 등을 통해), 이것은 다음과 같은 것일 수 있다:

Query (via wired, wireless, etc.) a unique identifier for a location, which can be:

-Unique ID of the network hardware at the charging place;

A unique ID of a locally installed smart meter, by communicating with the meter;

A unique ID, clearly installed for this purpose in any place; And

"소프트" (추정된 지리상) 위치를 설정하기 위해 GPS 또는 다른 신호 소스(셀, WiMAX 등)를 사용, 이것은 이후에 사용자 선호와 이력 데이터에 기초하여 정제됨(예를 들면, 차량은 이웃의 거주지가 아닌 소유자의 거주지(124)에서 플러그인되기 쉽다).

Use GPS or other signal sources (cells, WiMAX, etc.) to establish "soft" (estimated geographic) locations, which are then refined based on user preferences and historical data (e.g., vehicles are located in neighborhoods) Easy to plug in at the owner's residence (124).

9 illustrates an embodiment technique for determining a physical location on a grid 114 of electrical resources 112 connected to an exemplary power integration system 100. In one embodiment, the remote IPF module 134 obtains a Media Access Control (MAC) address 902 of a locally installed network modem or router (Internet access point) 302. The remote IPF module 134 then sends this unique MAC identifier to the flow control server 106, which uses the identifier to determine the location of the electric vehicle 200.

In order to identify its physical location, the remote IPF module 134 is also capable of communicating with the remote IPF module 134 "smart" utility meter 904, cable TV box 906, RFID-based unit 908, Or other unique identifiers or MAC addresses of devices physically installed in the vicinity that can communicate with the remote IPF module 314, including the example ID unit 910. ID unit 910 is shown in more detail in FIG. 10. Although the MAC address 902 does not always convey information about the physical location of the hardware component with which it is associated, in one embodiment the flow control server 106 associates a tracking database 912 that associates the MAC address or other identifier with the associated physical location of the hardware. ) In this way, remote IPF module 134 and flow control server 106 may find mobile electrical resource 112 wherever mobile electrical resource 112 is connected to power grid 114.

10 illustrates another embodiment technique for determining the physical location of the mobile electrical resource 112 on the power grid 114. Exemplary ID unit 910 may be plugged into grid 114 at or near the charging location. The operation of the ID unit 910 is as follows. The newly connected electrical resource 112 searches for locally connected resources by broadcasting a ping or message in the wireless reception area. In one embodiment, the ID unit 910 responds 1002 to the ping and passes the unique identifier 1004 of the ID unit 910 back to the electrical resource 112. The remote IPF module 134 of the electrical resource 112 then sends a unique identifier 1004 to the flow control server 106, which is located by the proxy and the location of the ID unit 910 by the proxy. The exact or approximate network location of the electrical resource 112 is determined based on the size of the area of charge.

In another embodiment, the newly connected electrical resource 112 searches for locally linked resources by broadcasting a ping or message that includes the unique identifier 1006 of the electrical resource 112. In this embodiment, the ID unit 910 does not need to trust or reuse the wireless connection and does not respond back to the remote IPF module 134 of the mobile electrical resource 112, but the electrical resource 112 received in the ping message. Reply 1008 directly to the control flow server 106 with a message including the unique identifier 1006 of its parent and its own unique identifier 1004. The central flow control server 106 then associates the unique identifier 1006 of the mobile electrical resource 112 in a "connected" state and determines the ID unit 910 for determining or estimating the physical location of the electrical resource 112. Uses another unique identifier of 1004. If a particular ID unit 910 is associated with only one exact network location, the physical location does not have to be estimated. The remote IPF module 134 knows that the ping is successful when it receives a confirmation from the flow control center 106.

This exemplary ID unit 910 is particularly useful in situations where the communication path between the electrical resource 112 and the flow control server 106 is over a wireless connection that cannot make an accurate determination of the network location by itself.

11 illustrates another embodiment method 1100 and system 1102 for determining the location of mobile electrical resources 112 on a power grid 114. In scenarios where electrical resource 112 and flow control server 106 communicate via a wireless signaling scheme, it is still desirable to determine the physical connection location during the period associated with grid 114.

Wireless networks (eg, GSM, 802.11, WiMax) include a plurality of cells or towers that each transmit a unique identifier. In addition, the strength of the connection between the tower and the mobile client connecting to the tower is a function of the client's proximity to the tower. When the electric vehicle 200 is connected to the grid 114, the remote IPF module 134 may obtain a unique identifier of the available towers, and tower the signal strength of each connection, as shown in the database 1104. IDs can be linked. The remote IPF module 134 of the electrical resource 112 sends this information to the flow control server 106 where it is combined with survey data such as the database 1106 to which the location inference engine 1108 is connected. The physical location of the electric vehicle 200 may be triangulated or otherwise deduced. In another implementation, the IPF module 134 may use the signal strength value to directly determine the resource location, in which case the IPF module 134 sends the location information instead of the signal strength information.

Therefore, an embodiment method 1100 includes acquiring 1110 signal strength information; Transferring 1112 the acquired signal strength information to the flow control server 106; And inferring 1114 the physical location using the stored tower location information and the signal obtained from the electrical resource 112.

12 illustrates a method 1200 and system 1202 of using signals from the GPS system to determine the physical location of the mobile electrical resource 112 on the power grid 114. Using GPS enables the remote IPF module 134 to determine its physical location on the power network in an inaccurate manner. This noisy location information from the GPS is transmitted to the flow control server 106, which uses it with the survey information database 1204 to infer the location of the electrical resource 112.

Embodiments Method 1200 includes obtaining 1206 noisy location data; Transferring (1208) the acquired noisy position data to a flow control server (106); And inferring a location 1210 using the stored survey information and the acquired data.

Example User Experience Options

Exemplary power integration system 100 may enable a number of desirable user features:

Data integration can include mileage and electric and non-electric fuel usage to allow derivation and analysis of overall vehicle efficiency (in terms of energy, expenditure, environmental impact, etc.). This data is output to the flow control server 106 for storage 716 as well as display on the in-vehicle user interface, charging station user interface, and web / cell phone user interface.

지능형 충전은 차량 행동을 학습하고 자동적으로 충전 시간을 변경한다. 원한다면 차량 소유자(408)는 오버라이드하고 즉시 충전을 요청할 수 있다.
