Abstract

Research on distribution network including VSC-connected distributed generation control has arouse more consideration due to the application of DC distributed generation. In this paper, a hierarchical economical MPC control strategy for VSCconnected DG is proposed to realize the efficient and economical control for VSC-AC system. Firstly, the dynamic characteristic of VSC-DG system is analyzed, and the time domain model for this system is established; secondly, the lower layer of overall control strategy is established, which utilizes MPC scheme to realize the track of power to reference value efficiently; then, a consensus protocol is established in upper layer to seek the power reference value for lower layer, realizing the economical distribution of active power; finally, simulation result of hybrid network model verifies the effectiveness of proposed control strategy.
