Distributed Reactive Power-Voltage Control Method of Micro-Grid

Abstract:

For micro-grid with multiple distributed power supply, a micro-grid distributed reactive power-voltage control method is proposed in this paper. By introducing active power disturbance, the load reactive power can be distributed in accordance with the distributed generation power rate, which leads to accurate distribution. At the same time, in order to ensure system voltage output stability in the rate, based on consistency and input/output linearization theory, under the distributed power multi-agent network topology, the distributed nonlinear co-droop controller is designed to make up for voltage fluctuation caused by active power disturbance. The simulation results verified the correctness and feasibility of the proposed control method.
