%X 低压农网配电线路不仅较长而且呈现出辐射状，在用电高峰期，部分配变低压侧经常出现电压过低的现象，电压质量问题突出。为解决上述问题，本文提出一种基于光伏和储能的电压质量改善方法。该方法以整个建设周期经济收益最大化为目标，考虑储能运行约束、节点电压约束等相关约束，采用蚁群算法求解分布式光伏–储能系统，建立了农网光伏–储能低电压治理的优化模型，最后通过IEEE-33节点为例进行验证。结果表明，光伏–储能系统能够在改善农网末端电压质量的基础上，增加整个配电网系统的经济收益，相比于无光伏储能系统更具备经济优势。<br />
The distribution line of low-voltage rural power grid is long and the branch structure is complex. The voltage of the low-voltage side of partial distribution transformer is often too low in the peak load period, and the voltage quality problem is prominent. To solve the above problems, this paper proposes a voltage quality improvement method based on photovoltaic and energy storage. This method takes the maximum economic revenue of the whole construction period as the goal, considers the constraints of energy storage operation, node voltage constraints and other relevant constraints, and uses ant colony algorithm to solve the optimal configuration of distributed photovoltaic (DPV)-energy storage system, establishes the optimization model of rural grid photovoltaic (PV)-energy storage low-voltage governance. Finally, the optimization model is verified by IEEE-33 nodes. The results show that the photovoltaic (PV)-energy storage system can increase the economic benefits of the whole distribution network system on the basis of improving the voltage quality at the end of rural power grid, and has more economic advantages compared with the non-PV energy storage system.
