摘要:
针对风光储直流(DC)微电网存在源荷的不确定性而导致系统功率不平衡的问题,提出一种分层协调控制策略。第一层控制风机、光伏、混合储能和并网变换器独立运行。第二层采用无需互联通信的直流母线电压控制策略,实现可再生能源的优先利用和各单元不同工作模式的平滑切换。第三层根据实时电价与交流电网故障情况进行并、离网运行状态的切换,以提高直流微电网运行经济性和可靠性。最后,在MATLAB/Simulink中进行直流微电网系统的仿真建模分析。结果表明,在4种不同的工况下,所提控制策略均能维持直流母线电压在380 V附近。

Abstract:
Aimed at the problem of system power imbalance caused by the uncertainty of source and load in the wind-solar-storage direct current(DC) microgrid, a hierarchical coordinated control strategy was proposed. The first layer controls the independent operation of the wind turbine, photovoltaic, hybrid energy storage and grid connected converter. The second layer adopts the DC bus voltage control strategy without interconnection communication to realize the priority utilization of renewable energy and smooth switching between different working modes of each unit. The third layer switches between on-grid and off-grid operation modes according to the real-time electricity prices and alternating current grid fault conditions to improve the economy and reliability of DC microgrid operations. Finally, the simulation modeling analysis of DC microgrid system is carried out in MATLAB/Simulink. The results show that the proposed control strategy can maintain the DC bus voltage near 380 V in four different operating conditions.
