摘要：To improve the utilization rate of micro sources of MMC series structured microgrid in a gridconnected operation mode, a prediction-based coordination control strategy of micro-source power of bridge arm is proposed in this paper. The connection between the output power and the delta carrier is determined by analyzing each generation unit’s output power. Each micro source’s output power is controlled independently by using the carrier-wave variable amplitude phase-shift modulation method. A finite control set-model predictive control algorithm is used to predict the next cycle’s power using the carrier amplitude of the current cycle as the controlled input. The optimal switching state for the next cycle is determined according to the coordination principle of “more work for more energy.” Through simulation, the coordination strategy can effectively control the maximum power output of the bridge arm and improve the micro source’s utilization rate.
