LOCAL CONTROL OF AN ELECTRICITY DISTRIBUTION NETWORK USING VOLTAGE-SOURCE CONVERTERS

A method of controlling an electricity distribution network, wherein the electricity distribution network is a mesh network including a plurality of loads and there is a voltage-source converter connected to a point in the network. The method comprises, while using the voltage-source converter to try to hold the voltage magnitude constant at said point, establishing a record of how, at said point, the real power flowing between the network and the voltage-source converter varies with variation of the reactive power that the voltage-source converter causes to flow between itself and the network, using a reactive-power value, proportional to the sum of the reactive-power draws of the loads, in order to look up a real-power value from the record, and configuring the voltage-source converter to supply into the network at said point reactive and real power at said reactive- and real-power values, respectively.
