摘　　要：大多数分布式发电系统存在发电功率及负荷随机性强、波动性大的特点,造成了分布式电源的应用难题。而配置了合理储能环节的微网,作为分布式电源的主要载体,为分布式电源并入传统电网提供了可能。研究了含分布式电源的微网控制技术,采用了基于改进下垂特性的控制技术来实现分布式电源的功率平衡,有效地保证了微网运行的可靠性。同时采用相应的控制技术对微网的储能装置进行改造,提高了能量缓冲的功能,保证了系统的安全性。Most distributed power generation systems have the characteristics of strong randomness of power generation and load and high fluctuation, which causes the application problems of distributed power supply. The microgrid equipped with a reasonable energy storage network, as the main carder of distributed power, provides the possibility for distdbuted power to connect to the traditional grid. The microgrid control technology with distributed power supply was studied, and the control technology based on improved droop characteristic was used to realize the power balance of distributed power supply and effectively guarantee the reliability of microgrid operation. The corresponding control technology was used for improving microgrid energy storage device to improve the energy buffer function and ensure the safety of the system.
