摘　　要：离网型风光互补发电系统是一种合理配置新能源的独立电源系统,由于自然界中风能、太阳能出现的不可预测性,以及负载、储能状态的随机性,提出一种基于风光互补发电系统多模态能量流的分析法,研究了各模态及模态间转化特性,给出了四种典型状态下风光互补发电系统的能量控制及管理。采用闭环电压控制使风力发电通道和光伏发电通道输出电压恒定,为用电设备和储能元件提供安全可靠的电能。通过MATLAB/Simulink软件对离网型风光互补发电系统多模态能量控制进行了仿真,结果表明离网型风光互补发电系统工作可靠,验证了多模态分析法的有效性。A Stand-alone wind-photovoltaic hybrid power system allocates new energy resources reasonably and independently.But the appearance of wind energy and solar energy is unpredictable,and their loading and storage states are random.Therefore,we analyze the flow of the multi-mode energy of the stand-alone wind-photovoltaic hybrid power system.We study its mode and modal transformation and then control and manage the energy in its four typical modes.We use the closed-loop voltage control to make sure that the output voltage of a wind turbine and the photovoltaic-generated power are stable and that the power supply for electrical equipment and electricity-storage components is safe and reliable.We use the MATLAB / Simulink to simulate the control of the multi-mode energy of the stand-alone wind-photovoltaic hybrid power system.The simulation results,give in Figs.4,5 and 6,and their analysis show preliminarily that the stand-alone wind-photovoltaic hybrid power system can work reliably,verifying that our multi-mode analysis method is effective.
