摘　　要：在能源安全新战略背景下,推动可再生能源发展、降低碳排放将是未来发展趋势。为了消纳大规模风电的弃风功率以提升电网的调峰能力,首先考虑阶梯式碳交易机制,采用碳交易市场,利用碳交易价格达到控制碳排放的目的;其次基于分时电价形成用户用电舒适度与用热舒适度,构建电热负荷需求响应模型,在掌握电锅炉、储热装置和热需求可时移特性的基础上,通过风电供给价格弹性系数描述风电出力与电锅炉协议电价之间的变化;最后通过综合满意度指标评估负荷响应能力,构建了考虑需求响应和阶梯式碳交易机制的含蓄热式电锅炉综合能源系统优化调度模型,实现系统经济运行,并采用CPLEX求解器对所构建模型进行求解。结果表明所提方法能够有效促进风电消纳,减少碳排放量且有效降低系统运行成本。In the context of new energy security strategy,promoting renewable energy development and reducing carbon emissions will be the future development trend.In order to eliminate the power of large-scale wind power abandoned power to improve the peak adjustment ability of the grid,the article first considers the stepped carbon trading mechanism,adopts the carbon trading market,and uses carbon transaction prices to achieve the purpose of controlling carbon emissions;secondly base on electricity comfort and thermal comfort,build an electrical load demand response model.On the basis of grasping the timing characteristics of electric boilers,heat storage devices and thermal demand,the price elasticity coefficient of the wind power supply is built to describe wind power and electric boiler protocol electrical prices.The changes between them,finally through the comprehensive satisfaction index assessment of the load response capacity,built an optimized scheduling model considering the demand response and the step-type carbon trading mechanism to achieve the system economy operation.Solve the model built using CPLEX Solver.The results show that the method can effectively promote wind power to reduce,reduce carbon emissions,and effectively reduce the operating cost of the system.
