熵权法根据各指标的变异程度，利用信息熵计算出各指标的熵权，再通过熵权对各指标的权重进行修正，从而得出较为客观的指标权重。(According to the variation degree of each index, the entropy weight of each index is calculated by using information entropy, and then the weight of each index is revised by the entropy weight, thus objectively obtaining the weight of each index.)

说明：  虚拟同步机技术是将分布式电源、电动汽车、储能以及负荷变流器模拟为旋转同步机的技术，使得电力电子变流器能够像同步机一样具有大电网的同步机制，从而实现电力系统的自主运行。虚拟同步机技术为解决集中式风光消纳、大规模分布式能源、电动汽车和储能为电力系统带来的一系列挑战提供了一条崭新的思路和解决方案。(Virtual synchronous machine technology is a technology that simulates distributed power supply, electric vehicle, energy storage and load converter as rotary synchronous machine. It makes power electronic converter have synchronization mechanism of large power grid like synchronous machine, so as to realize the autonomous operation of power system. Virtual synchronous machine (VSM) technology provides a new way of thinking and solution to a series of challenges brought by centralized solar energy absorption, large-scale distributed energy, electric vehicles and energy storage for power system.)
