针对风光互补微电网内风力发电系统和光伏发电系统运行特性,本文提出采用蓄电池储能系统(Battery Energy Storage System,BESS)与超级电容储能系统(Super Capacitor Energy Storage System,SCESS)下垂协调控制策略基础上对微电网母线电压采用对应的控制策略,进而优化无功功率控制,以此进一步提高对微电网内负荷供电的稳定性。文中针对微电网模式切换过程,加以控制策略理论分析,再通过PSCAD/EMTDC仿真软件,验证本文所提出控制策略的有效性及可行性。
英文摘要:
In view of the operation characteristics of the Wind/PV hybrid microgrid equipped with wind power system and photovoltaic power generation system, putting forward a droop coordinated control strategy of the battery energy storage system (Battery Energy Storage System, BESS) and super capacitor energy storage system (Super Capacitor Energy Storage System, SCESS) in the paper , then microgrid bus voltage with the corresponding control strategy, thus optimization of reactive power control, in order to further improve the load power stability of microgrid. Then through PSCAD/EMTDC simulation software, to verify the effectiveness and feasibility of the proposed control strategy.
