Definitions

  • the present invention relates to power distribution systems.
  • Power grids generally originated as local grids that grew over time, and were eventually interconnected for economic and reliability reasons. In general, these grids developed over time and became large with many power stations delivering power to major load centers using high capacity power lines. Some power grids are being adapted with or installed new with smart grid technology.
  • Smart grid can be used as an aggregate term for a set of related technologies, rather than a name for a specific technology.
  • smart grid technology can refer to the concept of an electrical grid that uses information and communication technology to gather and act on information, such as information about the behaviors of suppliers and consumers, in an automated fashion to improve efficiency, reliability, economics, or sustainability of the production and distribution of electricity.
  • One element of a smart grid is a smart meter that can collect and communicate information. Metering of electricity consumption is one way that bills can be generated in accordance with the level of consumption. Some existing technology takes advantage of electronic communication technology to vary rates depending on when power is being used. For example, a premium may be charged to purchase power during peak power usage times.
  • Another form of smart grid management involves the distribution of DC voltages for electronics and lighting.
  • Some LED lighting, laptop computer, cell phones and office electronics can use switching power supplies that supply DC voltages. In some applications higher AC supply voltages, such as 120-220VAC, are less important because lower DC voltages can be supplied and enable the same functionality.
  • DC voltages can power wireless nodes or hot spots that can power equipment wirelessly, i.e through inductive power transfer.
  • the cost of power may vary based on a variety of factors. One factor is the maximum amount of power to be delivered. Although the average amount of power at a given moment in time is likely well below the maximum amount of power, in order to provide the ability to deliver maximum power, even for a short period of time, costly extra infrastructure may be required to meet the maximum power demand.
  • a power management system receives information about the amount of manageable power available and can reallocate the manageable power.
  • devices communicate with a power management controller.
  • the power management controller is programmed to make power distribution decisions. For example, to determine whether power should be used locally or remotely.
  • wirelessly powered products use the device's power management to enable choices in local or more remote power distribution decisions and its available power becomes part of its environment.
  • Devices can be operated in a managed power mode where depending on power distribution decisions made by the power management system the device can be powered at full power, receive no power, or receive a base amount of power to enable some functionality.
  • Devices can operate differently in managed power mode. While in managed power mode, each device defines an amount of manageable power for the power management system. The manageable power is the amount of power that can be reallocated by the power management system. For example, some devices in managed power mode can be operated in standby mode without power (or little power). Other devices in managed power mode can be operated with a base amount of power and the manageable power is the difference between the full amount of power and the base amount of power to provide limited functionality.
  • the amount of manageable power for a device can vary depending on a number of factors such as, for example, a selected flexibility or priority rating by the user (i.e. how much manageable power does the user want to be made available or how much is the user willing to pay for power), the battery life of the device (if it has a battery), or based on varying power requirements of the device.
  • Power usage at a given moment in time can be reduced by providing power intelligently.
  • the power management system allows smaller power supplies to manage power intelligently.
  • the flexibility afforded by operating devices in managed power mode means that smaller power supplies can be used to service the same number of devices.
  • power systems can be designed to utilize more of the systems capabilities while still having maximum limits but utilizing that system design intelligently to enable smaller systems that enable more or expand capacities. This typically relates to less or smaller infrastructure demand and potentially lower costs as a system.
  • the power management controller can reallocate manageable power among various loads based on the configuration of the loads. For example, loads may be configured in a priority, managed, or standby configuration. Managed power can be allocated to priority loads first; any leftover power can be allocated to managed loads. If a standby load is reconfigured to a priority or managed state, manageable power from the managed loads can be reallocated appropriately, allowing each managed load to maintain a base amount of power. Additionally power systems can be designed to utilize more of the systems capabilities while still having maximum limits but utilizing that system design intelligently to enable smaller systems that enable more or expand capacities. This typically relates to less or smaller infrastructure demand and potentially lower costs as a system.
  • Manageable power that is not used for priority loads can be used to power the managed loads.
  • the manageable power can be made available elsewhere.
  • negotiation can occur so that power can be supplied dynamically in an intelligent way for charging and operation.
  • An example of this is where multiple laptop devices at a large conference table or within an office are charged intelligently.
  • the power distribution system can be configured to supply sufficient power to operate each laptop or operate and charge each laptop. This difference can be used to leverage timing and utilize smaller power supplies to negotiate a power sequence rather that assuming parallel power loads. That is, using one embodiment of the power distribution system of the present invention, the laptops may receive sufficient power for operation, but insufficient power to operate and charge. This can reduce costs and load demands.
  • Another example includes distributing power on a regional level efficiently; when a neighboring region has power demands, manageable power can be supplied to the neighboring region.
  • a method of power management in accordance with one embodiment includes: defining available power, defining a first subset of the available power as base power and a second different subset of the available subset as manageable power, configuring a plurality of loads, selecting load configurations, and supplying power according to the configurations, the amount of manageable power.

  • the graph also includes historical data that shows the historical maximum, minimum, and average values at each time for past Wednesdays.
  • the power demand management controller 118 can conduct load side power demand management, grid side power management, or both.
  • Load side power demand management includes managing when or how much power a load uses. That is, changes can be made on the load side to adapt to the amount of power available from the grid.
  • Grid side power management includes managing when or how much power the grid provides. That is, changes can be made on the grid side to adapt to the amount of power needed by the loads.
  • Load side demand management can be accomplished in a variety of different ways.
  • load side demand management can include scheduling loads to operate at different times, such as off-peak times, or demand side load balancing also referred to as demand management negotiations.
  • An example of load side demand management is a device that has a battery like a laptop, it can function in multiple modes, charging, operating, charging and operating or on under it's own power. By managing these devices in a larger environment like a large office building, power becomes manageable while still providing the same function.
  • a laptop can be configured to managed power mode.
  • the controller in the laptop can be programmed to communicate with the power management system and receive a variable amount of power depending on a variety of factors. For example, depending on the situation the laptop can communicate the status of the laptop battery, the amount of power to operate the laptop, the amount of power to maintain the charge state of the battery, and the amount of power to operate the laptop and increase the charge of the battery.
  • This information can be obtained from a power management chip on the laptop.
  • Other devices that have power management chips can interact in a similar way and provide battery information. Power management chips and the ability to communicate with the power management chip is discussed generally in the context of a wireless power supply in US Patent Publication 2010/0171461 to Baarman, filed Jan 5. 2010, which is hereby incorporated by reference in its entirety.
  • This information can be used by the power management system to allocate power to the laptop. For example, if the battery is full the power management system may trickle charge the laptop battery or choose to provide no power to the laptop and let it rely on its battery power. If no power is provided to the laptop, that power is available to be supplied to a different device - for example, a device that has a higher priority than the laptop. The laptop may be treated differently when the battery is empty or partially charged. For example, where the battery is empty or partially charged, the power management system may provide sufficient power to operate the laptop and then if additional power is available provide additional power to charge the battery.
  • the various thresholds for how to treat the laptop, how much power to provide and when to provide power to the laptop can vary depending on a number of different factors, such as battery life, power requirements, priority level.
  • the thresholds for these different factors may also be vary depending on the configuration of the system. For example, one user may be willing to pay more money to have their battery charged than another user so the power management system can factor that information into the decision about how much power and in what sequence to provide power.
  • a method for demand management negotiations is illustrated in Fig. 20. The method includes defining management opportunities 2002, understanding customer requirements and service levels 2004, and managing loads with intelligence and collaboration with the power grid 2006.
  • Negotiation based power management or negotiation based power balancing refers generally to managing the power distribution system based on back and forth interaction between the power grid and the loads connected to the power grid. For example, a device can communicate that it is willing to be operated with less power if the system determines that power could be used more appropriately elsewhere. In negotiation based power management some loads define management opportunities. An example of balancing would be in an office where an additional 1KW is needed.
  • the wireless power system can communicate the charge level of devices being charged to a power management system.
  • the power management system understands the reserve power available within the portable devices being wirelessly charged.
  • the wireless power system can also communicate battery capacity information in order to understand reserve amp hours of energy. This can provide a balancing opportunity for a period of time based on the real time requirements from each device. As charge is needed again the loads can then balance again and shift to other higher capacity devices in an active system always allowing some capacity to be switched.
  • a demand management opportunity refers to an opportunity to provide no or less power to a load so that power can be provided elsewhere. This can also be referred to as a demand balancing opportunity.
  • a management opportunity can be defined a number of different ways. For example, a user can select a configuration for a load that defines it as having manageable power, i.e. the user can define the management opportunity explicitly.
  • a device can have a demand management opportunity defined at the time of manufacture. For example, a device may be permanently configured to provide a demand management opportunity.
  • the controller should understand customer requirements and service levels. That is, the system may identify loads to provide power instead of the managed loads. This process of identifying higher priority loads can be done by user selecting a priority configuration for a certain load or can be done at the time of manufacture. For example, a load may have a priority configuration where a user pays a fee to ensure that load receives power before other loads. Alternatively, some loads may be permanently configured in such a priority configuration so that they receive power ahead of other loads. For example, emergency equipment may be configured in such a way.
  • the power demand management controller manages the loads using intelligence and collaboration with the power grid equipment. This can involve understanding the reserve capacity of battery powered equipment, general power requirements, usage times and priorities of need.
  • the battery systems can be used to transfer power from low load times to higher load demand time effectively transferring the power distribution. An example of this would be to charge devices at night or in a sequence when higher load demands are required.
  • Fig. 21 illustrates another embodiment of a method of demand management negotiation.
  • the method includes defining the available power, defining available power to manage, receiving any user configuration selections, communicating manageable power to the grid, and managing power demand side and grid side.
  • Grid management system defines the power available for an area for a period of time 2102. An area could be a household, group of households, or a larger region.
  • the available power to be managed is obtained, for example by registering the various loads in a database table 2104, such as the table illustrated in Fig. 17.
  • the user defines the priority service for each load 2106, for example by selecting service and premium for usage that drives power demand decisions.
  • the selected service can determine the economic cost of power, the amount of power the load receives, and the order in which loads receive power. Some loads may not have an option and instead may be hardwired with a particular priority service. Some loads may have a default priority service.
  • Each load communicates the manageable power or reserve battery capacity to a controller on the power management network 2108.
  • the demand side management controller associated with each load the grid management controller knows how much power is available to be managed and what services have been selected.
  • the demand side power management control manages power, for example the demand side control can manage power and changes requirements as the power grid makes requests.
  • the grid side controller manages power.
  • the demand needs can dictate both balancing and cost premiums. That is, the cost associated with standby, premium, and managed service can fluctuate dynamically depending on a number of factors. If there is an abundance of manageable power available, the cost for premium priority service can be decreased. However, if there is a scarcity of manageable power, the priority service cost may be increased or ceased from being offered at all. This is also when battery capacity may be utilized or even shared.
  • Balancing credits can be provided when the user distribution system has been configured to be managed in a flexible manor. If the transient loads can be minimized and the local system can be configured to a lower level the overall load footprint becomes more manageable. These credits can be applied reduction of overall billing as it simplifies and reduces the system load requirements. The better a system is balanced the more credits become available. Going over a defined balanced load target can negate or reduce credits as the idea is to balance the power used and set maximum thresholds that can be managed.

  • a user can configure priority settings and management information. That information can be communicated to a controller in the demand management network. Power control and scheduling can be performed. The user can select priority mode where the dishwasher will run immediately. Alternatively, the user can select standby where the dishwasher will run when the power management network instructs it to do so. The power management network can base this decision on a number of different factors. The user can also select demand managed whereby the dishwasher will run now, but if devices that have higher priority need power then it will run in a mode that uses less energy.

Abstract

Cette invention concerne un système de gestion d'électricité qui reçoit des informations concernant l'énergie disponible gérable et qui peut réaffecter l'énergie gérable. Selon un mode de réalisation, les dispositifs peuvent être commandés en mode d'énergie gérée où, en fonction des décisions de distribution d'électricité prises par le système de gestion d'énergie, le dispositif peut être alimenté à pleine puissance, ne pas être alimenté du tout ou recevoir une quantité d'énergie de base assurant un certain niveau de fonctionnement. La flexibilité assurée par le fonctionnement des dispositifs en mode d'alimentation géré signifie qu'il est possible d'utiliser des quantités d'énergie réduites pour alimenter le même nombre de dispositifs. Selon un mode de réalisation, le contrôleur de gestion d'énergie peut réaffecter l'énergie gérable parmi diverses charges sur la base de la configuration des charges. L'énergie gérable qui n'est pas affectée à des charges prioritaires peut être utilisée pour alimenter les charges gérées.
