摘要: 为实现光伏系统按照调度计划并网,配置混合储能调控上网电能,在划分蓄电池和超级电容器荷电状态区域的基础上,提出系统分层协调控制策略。首先,系统级调控对并网调度功率做出适时调整,为混合储能系统提供匹配光伏功率和并网功率的参考值;混合储能调控对混合储能系统的平滑功率参考值进行分配,实现蓄电池和超级电容器的合理充放电。然后,分析混合储能系统的变换器数学模型,设计相应的控制方法。最后,通过系统仿真,验证了所提分层协调控制策略的有效性、可行性,在不同荷电状态下光伏系统能够稳定运行、友好并网。

Abstract: In order to achieve grid connection of the PV system according to the scheduling plan and configure mixed energy storage to regulate the online electrical energy, a hierarchical coordinated control strategy for the system is proposed based on the division of the battery and supercapacitor SOC areas. firstly, system level regulation makes timely adjustments to the grid connected dispatch power, providing reference values for matching PV and grid connected power for hybrid energy storage systems. Hybrid energy storage regulation allocates smooth power reference values for hybrid energy storage systems to achieve reasonable charge-discharge of batteries and supercapacitors. Then, a mathematical model of inverter is analyzed and control method is designed. finally, the effectiveness and feasibility of the proposed hierarchical coordinated control strategy are verified through system simulation, and the PV system is able to operate stably and grid friendly under different SOC.

Key words: grid-connected PV, hybrid energy storage, layered coordination control, SOC, operational control
