摘　　要：为了提高分布式能源冷热电三联供系统的输出稳定性,进行系统优化配置,提出基于需求响应的分布式能源冷热电三联供系统配置优化方法。首先进行分布式能源冷热电三联供电的参数分析,以电压、交流侧电流及开关管电压为输入约束参量,根据需求响应进行分布式能源冷热电三联供系统配置目标函数构造,进行配置参数的优化分配。考虑系统控制延时的影响,进行三联供系统配置过程中的时滞误差补偿,结合需求响应降低采样及运算延时所引起的功率误差,实现分布式能源冷热电三联供系统配置算法的优化设计。仿真结果表明,采用该方法进行分布式能源冷热电三联供系统配置的适应度较高,输出时延较小,稳定性较好。In order to improve the output stability of distributed energy combined cooling,heating and power system,the system con-figuration optimization method based on demand response is proposed.Firstly,the parameter analysis of the distributed en-ergy CCHP system is carried out,and the voltage,AC side current and switch tube voltage are taken as the input constraint parameters.According to the demand response,the configuration objective function of the distributed energy CCHP sys-tem is constructed to optimize the configuration parameters.Considering the influence of system control delay,the delay error compensation in the process of configuration of CCHP system is carried out.Combined with the demand response to reduce the power error caused by sampling and operation delay,the optimal design of configuration algorithm of CCHP system with distributed energy is realized.The simulation results show that the proposed method has higher adaptability,smaller output delay and better stability.
