摘要
提出一种新型的VSG光-储分布式发电系统结构,该方案在传统光-储并网发电系统的逆变器后端另外添置了一套储能电池。这样不但可提高光伏组件的工作效率,避免光伏出力变化对系统频率造成影响,而且还可根据电网负荷的异常波动情况及时有效地输出有功及无功功率,达到稳定电网频率、电压的作用。系统的动态分析及仿真结果证明了该新型光-储并网发电系统结构能够实现新能源并网的目标与要求。
In this paper,a new structure of VSG PV and energy storages grid-connected distributed power generation system is proposed. A battery storage is adding to the back end of the inverter of the traditional structure system. Such structure can not only improve the work efficiency of photovoltaic modules,avoid that photovoltaic output changes affect the system frequency but also can output active and reactive power in a timely and effective manner and stabilize the power grid frequency and voltage according to the abnormal fluctuations of power load. The theoretical analysis and simulation results of the dynamic analysis of the system prove that the generator structure achieves the goals and requirements of the new energy grid-connected power generation system.
