Under the background of smart grid, the two-way interaction of grid side and user side keeps upgrading continuously.An automatic demand response strategy considering load characteristics and suitable for different users is proposed based on intelligent communication and automatic management system.Firstly, based on user`s historical data and real-time price, the strategy calculates the available electric power in every period of a day.Then an optimal scheme dicision model is established to choose optimal strategy of different period from a strategy set of various demand response schems.Different demand response strategies have their own advantages on priority, fairness and flexibility.The decision factor of the optimal decision model can be set differently according to users` different preference,thereby users` preferences and requirements are satisfied.The analysis results of example show that the proposed strategy can help user obtain favorable effect of energy saving, cut the electricity expenses, and decrease the load difference between peak and valley load of grid.%智能电网背景下,电网侧和用户侧的双向互动不断升级.基于智能通信和自动化管理系统,提出了一种计及电力负荷特性的适用于不同用户的自动需求响应策略.该方法首先以用户的历史用电数据和实时电价为基础,采用指数平滑模型求得当日各时段的可用电量.其后采用最优方案决策模型在含有各种需求响应方案的策略集中选择确定各时段的最优策略.需求响应策略在优先级、公平性和灵活性上侧重不同,用户可以根据自身偏好设定不同的决策因子,以满足自身的用电偏好和需求.算例分析表明,该策略能够帮助用户取得良好的节能效果,有效削减电力费用,并减少电网减少峰谷差.
