摘要:
A central plant that generates and provides resources to a building. The central plant includes an electrical energy storage subplant configured to store electrical energy purchased from a utility and to discharge the stored electrical energy. The central plant includes a plurality of generator subplants that consume one or more input resources. The central plant includes a controller configured to determine, for each time step within a time horizon, an optimal allocation of the input resources and the output resources for each of the subplants in order to optimize a total monetary value of operating the central plant over the time horizon. The total monetary value includes revenue from participating in incentive-based demand response programs as well as costs associated with resource consumption, equipment degradation, and losses in battery capacity.
摘要:
Described in this disclosure are embodiments for controlling a load and an energy source associated with an entity. A system may determine a first energy level, along with variability for the first energy level, associated with the entity for a first period (e.g., prior to a present time). The system may further determine a contextual data, along with variability for the contextual data, associated with the entity for a second period (e.g., after the present time). The first and second energy levels may be received from one or more control devices in communication with the system. The system may determine a second energy level associated with the entity for the second period. The second energy level may be based at least partly on the first energy level and the contextual data. The system may control, based at least partly on the second energy level, the load and the energy source.
摘要:
The use of smart microprocessor and sensor based controller system that enables selective management of energy supply into a household of the invention is illustrated and consists of four sub-components i.e., a Grid Power Supply System A, A Power Demand System (B), a Specially Designed Power Distribution Box (C), a Smart Energy Controller (D), a Solar Energy Secondary Power Supply and Timing System Unit E, and a RF Remote Control Unit (G). Energy is supplied through the city network grid (A) to a specially designed power distribution box which redistributes power to separate lines through a series of power relay switches (C1), each serving a different load category e.g., heavy, medium, low, essential lighting, special load systems, requiring special phase requirements (C2 to C6). More than one load can be connected in parallel to a specific line C3 to C6. A second switch bank C2 is optional which is individually supplied by separate lines supplied, either directly from green energy supplies such as solar or thermal systems, or indirectly after storage in a battery or thermal energy storage system.

摘要:
An electrical distribution site energy management and router device, or SER device, may be installed between a customer premises and a distribution grid, and one or more alternative energy sources and energy storage devices may be electrically connected to the SER device. The SER device may intelligently route power from alternative energy sources to the customer premises, energy storage devices, even to the grid, through various modes of operation. The SER device may efficiently and economically route power during peak electricity price periods and outside of peak periods.
摘要:
A power control device for controlling electrical power transferred between an AC power grid and a load or between the AC power grid and an auxiliary power source. For example, the power control device may be configured to monitor an electrical characteristic of electrical energy supplied by the AC power grid to the load and to adjust a consumption of the electrical energy by the load when the electrical characteristic indicates that the AC power grid is no longer in a state of balance. As another example, the power control device may be configured to control an electrical energy injection process during which an injection of electrical energy from the auxiliary power source into the AC power grid is increased in relation to a detected rate of deviation of the AC power grid frequency. As yet another example, the power control device may be configured to adjust an injection of electrical energy into the AC power grid according to a magnitude of kinetic energy bleed from the AC power grid that is derived during an occurrence of a power generation deficit within the AC power grid.
