摘要：

冷热电联产（combined cooling, heating and power，CCHP）系统与微电网的结合有利于促进消纳可再生能源，为了提升CCHP型微电网的经济性、环保性和稳定性，提出了两阶段优化调度模型。离线优化阶段基于需求侧响应策略，建立了基于归一化法向约束法的多目标规划模型，并用熵权-TOPSIS法筛选最优结果。在线优化阶段建立了基于动态矩阵控制算法的有限时域优化模型，对离线优化结果进行跟踪优化和反馈校正，以降低不确定性因素的影响。最后，设计对比方案进行分析，验证了所提优化模型的有效性。

Abstract:

The combination of combined cooling, heating and power (CCHP) and microgrid promotes the consumption of renewable energy. In order to improve the economy, environmental protection and stability of CCHP microgrid, a two-stage optimal dispatching model is proposed. The offline optimization stage is based on the demand response strategy, and the multi-objective model based on the normalized normal constraint method is established, and the optimal results are screened by the entropy-TOPSIS method. In the online optimization stage, a finite-time domain optimization model based on dynamic matrix control algorithm is established to track and optimize the offline optimization results with feedback correction to reduce the influence of uncertainty factors. Finally, a comparison scheme is designed to for analysis verify the effectiveness of the proposed optimization model.

Key words: CCHP microgrid, two-stage optimized scheduling, multi-objective optimization, normalized normal constraint method, dynamic matrix control algorithm
