Definitions

• End-user services come in many forms. There are electric utilities, water utilities, cable providers, sewer and steam providers, wireless and wireline communications, emergency monitors and responders, remote computer processing, to name just a few. All of these service providers deliver their product to (and sometimes receive product or information from) end-users at a premise or group of premises.
• 'premise' and 'premises' is used interchangeably herein and includes, without limitation, a single home, a business, a building, a factory or other facility, grounds, vehicles, containers, industrial plants, treatment facilities, stadiums, parks, farms, etc. and includes combinations, aggregates or portions thereof.
• Some of these premises are used for delivering services and some for receiving services, but each of the premises can be either an end-user of services or a provider of services or both.
• Abnormal conditions can be caused by the service provider, or user, or by the premises itself. It is also necessary to measure and verify "compliance" by the end-user to the service agreement (e.g., if a user complied to the request to reduce energy or not).
• Power generation and delivery include complex relationships involving, for example, frequency, voltage, and active and reactive power, all of which must track the changing load exactly to avoid catastrophic consequences. Because load changes constantly, it affects operating and generator fuel requirements, costs, system efficiencies, grid constraints, power quality, and reliability which in turn affect environmental concerns such as air emissions, water use for power generation or cooling, and land use.
• Real-time billing requires real-time measurement of sufficient parameters as well as the communications infrastructure to send real-time information. Lack of real-time billing causes a lack of demand responsiveness to price because people do not see price fluctuations at the time of use. Within the practice of economics this is called "demand inelasticity". It is important to note that adding ntw real-time meters without adding real-time customer-directed, system-level, device-level, and/or appliance-level automated load management does little to help demand-side responsiveness.
• Real-time customer controlled automated power management requires real-time metering and sub-metering for every significant load, and/or service, secure bi-directional communications between loads and customer, and a method of automating customer response preferences.
• Lack of real ⁇ time, customer-controlled, automated power management within the premise causes a lack of demand response because people cannot be expected to spend their time watching a real-time meter and then scurrying to manually adjust services and /or load settings elsewhere.
• One concept for achieving such reduction is to change the cost of consumed power as usage (delivery costs) increases.
• usage delivery costs
• the user needs to know the current power price so the user will shed load.
• Some users will be concerned, while others might not be.
• Some will turn off HVAC services such as air conditioners, while others might turn off lighting related services.
• such arbitrary shedding could actually cause more distribution problems then are solved. For example, so many people could turn off their air conditioners that so much power would be saved that one or more generators could go off line thereby prolonging the power shortage problem instead of fixing it.
• the system could shed power just when it needs it the most.
• thermostats have been around for over 20 years, with millions sold. Yet very few are used to automate energy conservation and are instead used simply as manual thermostats with digital readouts. Because other loads are not orchestrated with the thermostat, and because other loads can start and run while the higher price signal is being sent to the thermostat, there is no way to verify or accurately predict the specific amount of load being shed by the price signal when it is most needed and no way to know the real effects of using only a thermostat-base load shed system. Because there is no submetering at the air conditioning unit in this approach, and therefore no direct verification that load was shed because of direct interaction with the thermostat by the end-user, some of the direct reward to the end-user is lost as is end- user motivation to participate.
• the present invention is directed to systems and methods which allow each end-user (or a combined number of end-users, herein called premises) to set and operate controls for each of its energy using services, systems, devices and/or appliances.
• Each premise then can determine, based on signals supplied from a central control point, how it will manage its power consuming services, systems, devices, and/or appliances.
• this system and method ties into a network of sensors which, in turn, is tied into a larger network that controls the distribution system throughout a wide area.
• sensors associated with each service, system and/or piece of equipment on a premise feeds data back to a main control unit serving that premise so as to form a digital copy of the premise.
• This digital copy is used to control power, and other service parameters, of the premise.
• the digital copy is also fed to larger nodes which, in turn, can feed the data to the wide area network. In this manner a digital copy of many premises is achieved.
• each premise control unit Upon a signal from the central control source (for example, to reduce power by 10%), each premise control unit then looks to the digital copy of the premise (as obtained from the various services and/or devices associated with the premises and makes decisions as to what would be the best way for that control unit to effect the desired reduction at this time.
• the action(s) taken (and to be taken) is fed back to the main network for use in further determining whether the overall system has accomplished its goals.
• the system instructs subsequently reporting controllers to not take the action contemplated or to reverse (or reduce or otherwise alter) an action already taken. This then achieves interactive management of the power distribution system with respect to the overall system and with respect to a particular premise and reduces oscillation in the network.
• the premise system has sensors in various rooms to keep track of all the parameters occurring in the room. Accordingly, if, for example, a sensor has not detected motion for a period of time the assumption can be made that a room, or set of rooms, is unoccupied. Lighting and/or HVAC service (lights, heating, cooling, for example) can be reduced in those rooms without any undo distress. Other services could include metering and sub-metering, energy management, security monitoring, safety monitoring, fire protection/monitoring, medical monitoring, wireless communications, telephone, premise (home) automation, equipment monitoring, data storage, surveillance monitoring, digital entertainment, etc. Thus, the power-using environment can be tailored to the user and/or the actual use of the premises while conserving energy.

Intermediate distribution point 12-1 would then communicate with a large number, perhaps 4,000 or more, premises. Within each premise, an intelligent services director (IDS) such as ISD 30- would be the central gateway for assembling and maintaining a digital copy of that premise's environment. That information (i.e., the digital copy of the environment) is stored with the ISD and also transmitted to the intermediate distribution point serving that ISD. Such communication could be via several modes of communication, such as, for example, 802.1 1, Internet, modem or cell phone, etc. Also note that there could be several levels of intermediate distribution points serving a particular residence or premises.

All of these actions are taken under control of the ISD, based on data coming from individual modbots working as a unified whole under the ISD supervision for that location. Even without input from water usage bots, the ISD, based simply on water usage (or a light coming on in a room) can determine that this activity is improper because the alarm has not been reset and that the expected condition is that no one should be in the premise.

• the communication and cooperation among delegates (which run on modbots, ISDs, and elsewhere and could be incorporated as applications running on each device processor) for the purpose of power management takes the form of a computational market in which delegates, using virtual money, represent buyers and sellers of Distributed Energy Resources (DER), (such as, for example, the modbots), including energy management, distributed generation, distributed energy storage, weather adjusted information (via temperature sensors in modbots), and grid locational/condition information, among other services.
• Delegates communicate and negotiate, in a free-market bidding-like manner, to achieve the desired objectives of all stakeholders.
• Delegates are autonomous within their hierarchy: Delegates operate without intervention of humans and others, accept input from local sensors, and have control over their internal states, within their hierarchy. Within the hierarchy, delegates can be grouped to meet specific requirements (i.e., security levels).
• Delegates must represent someone: At the appropriate juncture in a transaction, delegates must disclose whom they represent.

• Delegates are preprocessed to efficiently provide optimized solutions by a specially packaged version of Optimal' s QuixFlow analysis and optimization technology. It is important to note that the formation or change in formation of supply/demand relationships presents difficult coordination issues. Delegates must simultaneously negotiate transactions at multiple levels, with important interdependencies among inputs and outputs at each level. Although this often requires optimization, it does not require a change in system topology, database schemas, or algorithm. In other words, although the data is dynamic, the process itself can be set to definitive software (remotely upgradeable) protocols.
• Incorporate transactions which themselves may consist of several messages, which are detailed in the information-exchange topology and data base schemas.
• This topology and the database schemas are based on algorithms that predefine communication types and patterns and allow the message protocols to be built, updated, distributed, and redistributed in a structured and efficient manner.
• the system is remotely changeable and upgradeable - system updates do not require end-user or utility personnel input or maintenance.
• the delegate receives, or in the event of communications failure has received, instruction from the hierarchy above it, and because it acts on new, locally-gathered sensor data, it continues to function to meet a defendable result based on the instruction(s) from the hierarchy above and continual data from local sensors.
• delegates do the following:
• each locally-optimizing delegate can dynamically re-control within its hierarchy to best meet local and system-wide objectives.
• the highest delegate in the hierarchy as it then exists acts like a totally-informed, centralized control algorithm.
• cooperating delegates automates and encourages beneficial transactions, and lessens system growth problems such as intractable information structures, message delays, and dynamic changes in the system topology.
• a transaction in this context consists of software delegates informing, requesting, offering, accepting, rejecting, competing with, and assisting one another.
• the local ISD could determine that the power is likely to be turned down because of events monitored at the local system, and could begin to take those actions even before being instructed to do so. Also, as power becomes sensitive to cost throughout a day, the ISD can keep track of the power costs (on a minute-by-minute basis) and can turn equipment on and off as the price of electricity rises and falls throughout a day to take advantage of lower costs for a consumer. These actions are configurable under control of a processor and memory in the ISD working in conjunction with intermediate distribution point 12 and central control 11 (FIGURE 1 and 2). The ISD communicates its actions to control 11 and thus power consumption across the entire distribution system is known precisely. Also, in some cases where power factor is critical, the ISD, in conjunction with the local modbots, could add or subtract load based on the power factor of the load.
• FIGURE 7 depicts one embodiment 70 of a platform for the unification of multiple services to and from a premises.
• the ⁇ platform is deployed for one service it can used for multiple services as shown.
• Elements 701-715 depict some of the services that can be unified for a premises and these can be expanded upon, or combined as desired and can include sensors and/or controls and individual devices, applications, communication equipment, etc.
• Embodiment 70 is not intended to be an exhaustive list of services but mere representative one.
• the unified approach works both inbound to the premises as well as outbound there from and relies on the fact that the central controller, ISD 30- in this case, maintains a coherent view of the premises with respect to environmental conditions, such as power consumption, on a device by device (or zone by zone) basis.
• any service provider need only communicate with the ISD to be in communication with any or all of the premises 1 sensors/controllers.
• the hardware and software components do not have to be converged by themselves, but will provide a unified view to an outsider.
• the outsider would see, for example, one or more of: 1) a single integrated hardware platform regardless of how many hardware components are added; 2) a single integrated communications platform, again regardless of how many components are added; 3) an integrated operating system regardless of how many software components are added; and 4) an integrated user interface regardless of how many "views" and how many view-port displays are available or added.
• This platform also provides the ability for automation of home, building, facility, ship, or other space or operation for the user that is fully configurable by the user. For instance, some users might want all the lights turned out if no motion is detected in a room for a certain period of time. Other automation includes functions such as "when the security system is set incoming phone calls are automatically forwarded to a cell phone". Or, if the security system is set and excess water is being used or excess gas is being used, then the system can turn off the gas or water and alert the user, or if appropriate, alert emergency responders.
• the different services that are available with the infrastructure that has been created in each premise allows multiple different services available to the user.
• the system also can provide a user telephony control as well as using the intrinsic high speed communications for voice over IP, Internet, audio, video, and high speed Internet connection services, etc. All of these features are placed onto the same system or backbone throughout the premise and provide a low-cost, easy way of managing systems in the premise as well as managing communications.
