Cooperative Model Predictive Control for Distributed Photovoltaic Power Generation Systems

Abstract

In this paper, we investigate a cooperative model predictive control for distributed photovoltaic (PV) power generation systems. A two-level control strategy is proposed. The upper level is cooperative control and the lower level is model predictive control based on dynamic matrix control. The proposed control strategy not only makes all the distributed PV generators converge and operate at the same ratio of the available power, but also regulates the total power output of all the PV generators to ensure the stability of the distributed power generation systems. Simulation results on the 4-machine 14-bus distributed power generation test system are provided to verify the validness and effectiveness of the proposed control strategy.
