摘要
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,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,验证文中所提出控制策略的有效性及可行性。
In view of the operation characteristics of the wind power system and photovoltaic power generation system at the Wind/PV complementary microgrid, this paper put forward a corresponding control strategy for the microgrid bus voltage on the basis of the droop coordination control strategy of combining the Battery Energy Storage System ( BESS) and the Super Capacitor Energy Storage System ( SCESS) , and optimized the reactive power control so that the load power stability of the microgrid could be further improved.The paper described the mode-switching process of the microgrid, analyzed the control strategy in theory, and verified the effectiveness and feasibility of the proposed control strategy through the PSCAD/EMTDC simulation software.
