摘　　要：针对如何实现居民侧与电网侧的友好互动问题,建立并网两阶段优化模型。第一阶段以住宅区用户用电成本最低为优化目标,第二阶段以加入光伏-储能并网运行下平均回本年限最短为优化目标。首先利用概率统计思想简化多用户调度模型,将其等效为4类特征用户调度之和,采用PSO算法进行求解,其次提出一种住宅区家庭能源管理系统以及能源交易模式,并对该交易模式进行投产分析。算例分析结果表明,住宅区并网两阶段优化模型调度系统可有效降峰调谷,节约用电成本。Aiming at the problem of how to realize the friendly interaction between the residents side and the grid side,this paper establishes a two-stage optimization model for grid connection.In the first stage,the optimization goal is to minimize the cost of electricity for residential users.In the second stage,the optimization goal is to minimize the average return period under the addition of photovoltaic-energy storage grid-connected operation.Firstly,the multi-user scheduling model is simplified by means of probabilistic statistics,which is equivalent to the sum of four types of characteristic user scheduling and solved by PSO algorithm.Secondly,a residential home energy management system and energy trading mode are proposed,and the trading mode is put into production analysis.The results of the example analysis show that the two-stage optimization model dispatching system can effectively reduce the peak and adjust the valley,and save the electricity cost.
