　　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 in -dependently.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 hy-brid 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 .
