| Abstract: | A system and method for control of dispatchable resources on an
electrical power distribution grid is disclosed. The disclosed method
provides improved response to power imbalance based on a communications
signal independent of system frequency. The communication signal provides
a feed-forward control of dispatchable power resources. A communications
network is employed to generate a signal to dispatchable resources that a
power imbalance has occurred. Due to fast response power transmission
network interfaces associated with the dispatchable resources, the
respective resources respond in significantly less time than feedback
controlled conventional generators which depend on line frequency
sensing. The rapid response mitigates the impact of power imbalances and
enables greater penetrations of converter-interfaced power generation
units such as renewable energy sources to be connected to the grid. |
