摘要
在“双碳”背景下,为准确突出需求响应的实际特点和解决传统微电网中可再生能源利用率低、负荷峰谷差大以及两主体利益无法均衡的问题,文中提出计及需求响应与主从博弈的微电网低碳优化调度模型。首先,考虑负荷变化量与电价变化量之间的非线性关系,构建基于指数关系的价格型需求响应机制优化用户负荷与其峰谷差;然后,结合激励型需求响应与碳交易机制建立以微电网作为领导者,用户作为追随者的低碳主从博弈模型;最后,通过KKT条件将双层博弈模型转化为单层规划问题求纳什均衡解,并通过算例验证了模型的有效性。算例结果表明,所提模型准确地描述了实际需求响应特点,实现了削峰填谷;并且也提高了微电网中的风光利用率和利润,降低了微电网的碳排放量。
Under the background of″dual carbon″,in order to accurately highlight the actual characteristics of demand response and solve the problems of low utilization rate of renewable energy,large peak⁃valley load difference and unbalanced interests of the two main bodies in traditional micro⁃grids,a low⁃carbon optimal dispatch model of micro⁃grid considering demand response and Stackelberg game is proposed in this paper.The nonlinear relationship between the load change and the electricity price change is considered.A price demand response mechanism based on the exponential relationship is constructed to optimize the user load and its peak⁃valley load difference.In combination with the incentive demand response and carbon trading mechanism,a low⁃carbon Stackelberg game model taking micro⁃grid as the leader and users as followers is established.The two⁃layer Stackelberg game model is transformed into a single⁃layer programming under the KKT condition to obtain a Nash equilibrium solution.The validity of the model is verified by examples.The experimental results show that the proposed model can accurately describe the actual demand response characteristics,realize peak shaving and valley filling,improve the wind and solar utilization rate and profit in the micro⁃grid,and reduce the carbon emission of the micro⁃grid.
