METHOD AND SYSTEM FOR REGULATING POWER OF AN ELECTRICITY GRID SYSTEM
First Claim
1. 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 store is faster than that of the source;
a first switch connecting said store to said 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 energy stored in the store and energy available from said source and for selectively controlling the first switch to close to transfer energy from the source to the store;
a second controller configured to monitor energy stored in said store and, on receiving an indication that additional energy is needed in the grid, if the energy stored in the store exceeds a supply threshold, controlling the second switch to close to transfer energy from the store to the grid.

Abstract
A power regulation system for an electrical grid has a store of electrical energy connected through a first switch to a source of electrical energy. The response time of the store is faster than that of the source. A second switch is connected to the store at one side with the opposite side for connection to the grid. A first controller monitors energy stored in the store and energy available from said source and selectively controls the first switch to close to transfer energy from the source to the store. A second controller monitors energy stored in said store and, on receiving an indication that additional energy is needed in the grid, if the energy stored in the store exceeds a supply threshold, controls the second switch to close to transfer energy from the store to the grid.

15. A power regulation system for an AC grid, comprising:
-
a capacitive store able to supply energy on command within a first response time; a first switch connected at one side to said capacitive store and for connection, at an opposite side, to a kinetic battery able, at least intermittently, to supply energy on command within a second response time, said first response time being faster than said second response time; a second switch comprising a power inverter, said second switch connected at one side to said capacitive store and for connection at an opposite side to said AC grid; a first controller connected to monitor voltage of said capacitive store and energy available from said kinetic battery and configured to control said first switch to close to transfer energy from said kinetic battery to said capacitive store, when said voltage of said capacitive store falls below a lower threshold and said kinetic battery has available energy; a second controller connected to monitor voltage of said capacitive store and intermittently receiving a request to supply additional energy to said grid, said second controller configured to control said second switch to close to transfer energy from said capacitive store through said power inverter to said AC grid on receiving a request to supply additional energy to said grid, when voltage of said capacitive store exceeds a supply threshold. - View Dependent Claims (16)
