Abstract
Based on model predictive control theory, this paper presents a kind of control strategy for the bidirectional AC/AD converter in AC/DC hybrid micro-grid which is to balance energy flow between AC and DC sub-grids and ensure safe and reliable operation of the system.Therefore, it establishes a dynamic model for the bidirectional AC/DC converter which is able to predict the output value of the next sampling time of system according to the discrete time model and under the condition of limit space vector of converter voltage.This model can also determines the state of switch tube by using value function.Simulation results indicate that the proposed control strategy is feasible and effective.关键词
