Control Of Energy Storages In A Microgrid

摘要

A method performed by a first control unit for controlling a first energy storage in a microgrid. The method includes calculating a first storage capability parameter for the first energy storage; transmitting capability information about the first storage capability parameter to a second control unit configured for controlling a second energy storage in the microgrid; receiving capability information about a second storage capability parameter for the second energy storage from the second control unit; calculating a first power sharing ratio for the first energy storage, based on the first and second storage capabilities; and sending control signals including information based on the calculated first power sharing ratio, for controlling the first energy storage to inject an amount of power (P) into the microgrid in accordance with the first power sharing ratio for correcting an observed deviation (Δf, ΔV) in the microgrid.

1. A decentralised control method performed by a first control unit for controlling a first energy storage in an electrical power microgrid comprising a plurality of energy storages each comprising a respective control unit, the method comprising:
calculating a first storage capability parameter for the first energy storage of the plurality of energy storages; transmitting capability information about the first storage capability parameter to at least a second control unit configured for controlling a second energy storage of the plurality of energy storages; receiving capability information about a second storage capability parameter for the second energy storage from the second control unit; calculating a first power sharing ratio for the first energy storage, based on the first and second storage capabilities; receiving, from the second control unit, ratio information comprising information about a second power sharing ratio for the second energy storage, as calculated by the second control unit; adjusting the calculated first power sharing ratio based on the received information about the second power sharing ratio; and sending control signals comprising information based on the calculated first power sharing ratio, for controlling said first energy storage to inject an amount of power into the microgrid in accordance with the first power sharing ratio for correcting an observed deviation in the microgrid.
