Patent ID: 8803363

Claim:
A power regulation system for an electrical grid comprising: a store of electrical energy; a source of electrical energy, wherein an energy supply response time of the stole is faster than that of the source; a first switch connecting the store to the source; a second switch connected to the store at one side and having an opposite side for connection to the grid; a first controller configured to monitor an amount of energy stored in the store and an amount of energy stored in the source and to selectively control the first switch to close to transfer energy from the source to the store provided that the amount of energy stored in the source is above a minimum source amount or to transfer energy from the store to the source provided that the amount of energy stored in the source is below a maximum source amount; a second controller configured to monitor the amount of energy stored in the store and to control the second switch to close to transfer energy to the grid provided that the amount of energy in the store is above a minimum store threshold or to absorb energy from the grid provided that the amount of energy in the store is below a maximum store threshold, wherein the power regulation system operates in accordance with a regulation signal to transfer energy to the grid or to absorb energy from the grid.
