针对包含光伏、储能等多电源的微电网电能质量控制，传统方法是采取加装电能质量监测装置，通过对历史运行数据进行分析，并不断调节运行控制参数或独立安装电能质量治理装置来保障微电网稳定运行，治理效果单一，并且无法实现微电网电能质量实时控制。为此，提出一种基于边缘计算的微电网电能质量控制系统，结合边缘计算技术和逆变器(变流器)资源复用原理，实现动态的电能质量采集、分析和就地控制与调节，提高了微电网电能质量实时调节效率，通过前期合理规划，一方面节约了后期微电网电能质量治理改造投资，另一方面提高了微电网的电能质量运行水平，对于微电网的经济稳定运行有一定的参考价值。

To include photovoltaic (PV), energy storage power of microgrid power quality control, the traditional method is to add the power quality monitoring device, through the analysis of historical operation data, and constantly adjusting the parameters of the operation control or independent installation of microgrid power quality control device to ensure stable operation, single governance effect, and can't realize the microgrid power quality control in real time. For this, put forward a method based on edge calculation method of microgrid power quality control system combined with edge computing and inverter (current transformer) resources reuse principle, realization of dynamic power quality sampling, analysis and on-site control and adjustment, improve the efficiency of the microgrid power quality real-time adjustment, by reasonable planning. On the one hand, it saves the investment of power quality management and transformation in the later stage of microgrid, and on the other hand, it improves the power quality operation level of microgrid, which has certain reference value for the economic stable operation of microgrid.
