由于忽略配电网安全约束,以经济性最优作为目标函数的微电网优化调度存在不足,所得到的经济性最优调度方案往往会导致电压幅值越限、联络线路过负荷等问题,影响电力系统的安全稳定运行.文章以微电网的经济性最优与配电网的安全性最优为目标,提出一种改进的非合作博弈模型,将自回归滑动平均法和场景削减技术加入模型,对风光等不确定性因素进行处理.阐述模型建立的方法与步骤,详细分析模型的原理.使用某地实际配电网数据进行试验,微电网经济调度模型、配电网安全调度模型、非合作博弈模型的对比结果表明:非合作博弈模型更符合实际电网运行要求,既满足微电网利润要求,又达到配电网安全约束,比传统方法更适合电力市场.

Due to ignoring distribution network security constraints, the method of the optimal scheduling ofmicrogrid which takes economic optimization as objective function has some shortcomings that lead to the limit ofthe voltage amplitude, tie line passing load etc., and eventually affect the safe and stable operation of powersystem. This paper aims at the economic optimization of microgrid and the security optimization of distributionnetwork and proposes a non-cooperative game model that considers the economy and security of the microgrid,and deals with the uncertain factors such as wind and light based on auto regressive and moving average methodand scene reduction technology. The method and steps of model building are described, and the principle ofmodel is analyzed in details. Using data for experiment, the comparison results of microgrid economic dispatchingmodel, security dispatching model and the non-cooperative game model show that the non-cooperative gamemodel is more in line with the actual power grid operation requirements, meeting not only the profit requirementsof micro grid, but also the security constraints of distribution network, and more suitable for electricity marketthan the traditional methods.
