ADAPTIVE ENERGY MANAGEMENT SYSTEM
First Claim
1. A system for controlling power flow to a facility, the system comprising:
- a controller for controlling power flow to said facility and for controlling elements of said system;
a power bus for coupling elements of said system to said controller and to one another;
at least one energy storage unit element for storing energy, said at least one energy storage unit element being coupled to said power bus;
at least one power source element for generating power, said at least one power source element being coupled to said power bus;
at least one power load located at said facility, said at least one power load being controlled by said controller;
whereinsaid controller controls said power flow to said facility based on at least one of;
weather data;
geographical data;
occupancy data;
historical data for power consumption of said facility;
operating conditions of said system;
predicted power demands of said system; and
user entered preferences.

Abstract
Systems, methods, and devices related to a microgrid system for providing power to a facility. A self-contained power system provides power to a facility using a combination of power storage elements and renewable energy sources. A connection to an external power grid may also be provided. The system optimizes power flow to the facility using power from the storage elements and the renewable energy sources and, if necessary, the external power grid. The optimization process predicts future power usage by the facility using power usage data from a predetermined time window. The optimization process can also take into account predicted energy generation amounts by the renewable energy sources. To optimize economic effects, the optimization process can also determine whether to buy and when to buy power from the external power grid.

11. A method for optimizing operations at a system which controls power flow to a facility, the method comprising:
-
a) gathering power usage data by said system over a predetermined period of time immediately preceding a set point in time; b) predicting power usage by said system for a predetermined future period of time based on said power usage data, said predetermined future period of time being immediately succeeding set point in time; c) predicting an amount of power generated by renewable energy sources in said system for said predetermined future period of time; d) determining a net demand for power for said system based on said power usage predicted in step b) and said amount of power predicted in step c); e) determining whether to draw power from energy storage unit elements in said system for said future period of time based on said net demand for power for said system; f) determining whether to draw power from an external power grid for said future period of time based on said net demand for power for said system, said external power grid being coupled to said system. - View Dependent Claims (12, 13, 14)
