摘　　要：为了开展微电网关键技术研究,内蒙古电力科学研究院建设了微网综合实验平台,微电网主要包括光伏、风力发电机等新能源发电设备,充电桩等常投切的大负载和办公室电源等相对稳定的小负载。基于该实验平台,进行了离网运行时多PCS(功率调节系统)协调控制、混合储能平滑控制、光储一体化PCS、联络线功率控制等控制策略实验研究,结论为:离网模式下2台PCS在不同的负荷变化扰动下主电源出力稳定,主、辅电源的协调控制能够保证离网情况下微电网供电的可靠性;实验平台配置的超级电容器和电池的混合储能方式可实现平滑控制;采用不同的控制手段,通过对储能设备的充放电控制、分布式电源出力控制以及自动减载控制等,可达到平抑并网联络线波动的目的,将微电网变为可计划性输出的友好能源。Inner Mongolia Electric Power Science ＆ Research Institute constructed the microgridcomprehensive experiment platform for the purpose of carrying out microgrid key techology research. Mircrogrid consists of new energy power generation equipments and different loads. Based on the experimental platform, more PCS （power conditioning system） coordinated control as off-grid running, hybrid energy storage smooth control, optical storage integration of PCS and other experimental research were carried out. The conclusion is that main power output of 2 PCS is stable under different load disturbance in off-grid mode; coordinated control of main, auxiliary power supply can ensure microgrid power supply reliability under off-grid cases; the super capacitor and battery hybrid energy storage can realize smooth control; the usage of different control methods can achieve the purpose of smooth grid tie line fluctuations, which can put microgrid into planned friendly output energy.
