摘要
建筑屋顶拥有丰富的太阳能资源,传统光伏发电普遍采用直接并网方式。但是,太阳能的利用具有不可预测性,会导致电网潮流波动异常,同时用电微网接入充电桩等大功率负载,会导致电力系统供需不平衡。基于光伏电源和市电电源,本文构建一种交直流混合微网控制系统。该微网控制系统通过交流/直流变换器、直流/直流变换器连接交流电源、直流电源、交流负荷和直流负荷,并进行能量调控,可以满足用户交流电、直流电的供电需求。
The roofs of buildings have abundant solar energy resources,and traditional photovoltaic power generation generally adopts direct grid connection.However,the utilization of solar energy is unpredictable,which can lead to abnormal power flow fluctuations in the power grid,at the same time,the connection of power microgrids to high-power loads such as charging piles can lead to an imbalance between supply and demand in the power system.Based on photovoltaic power supply and mains power supply,this paper constructs an AC/DC hybrid microgrid control system.The microgrid control system connects AC power,DC power,AC load,and DC load through AC/DC converters and DC/DC converters,and performs energy regulation to meet the power supply needs of users for AC and DC power.
