摘　　要：传统建筑冷热电三联供系统忽略了储能特性,不考虑储能参与决策,系统无法调节储能压力,造成能源浪费,为此文章提出考虑储能特性的混合负荷跟随运行策略。同时,为减少模型计算量,精准选取负荷典型日,提出了结合标准间冲突性相关性(criteria importance though intercrieria correlation,CRITIC)加权的K-means聚类算法选取典型日。从经济、能源、环境三方面对系统进行优化。优化结果显示,采用CRITIC赋权的K-means聚类算法轮廓系数更高,具有更好的聚类效果;同时,提出的考虑储能特性的混合负荷跟随(following hybrid load-energy storage characteristics,FHL-ESC)运行策略综合指标达到29.66%,远高于电负荷跟随策略和热负荷跟随策略。与传统运行策略相比,所提出的运行策略综合表现最优,验证了所提运行策略的可行性和优越性。As the cooling,heating and power system for traditional buildings ignores the energy storage characteristics and does not consider the participation of energy storage in decision-making,it cannot adjust the energy storage pressure,thus resulting in energy waste.Therefore,a hybrid load-following operation strategy considering energy storage characteristics is proposed in this paper.At the same time,in order to reduce the amount of model calculation and accurately select typical day of the load,a K-means clustering combined with CRITIC weighting is proposed.The system is optimized from three aspects:economy,energy and environment.The optimization results show that the K-means clustering algorithm with CRITIC weighting has higher contour coefficient and better clustering effect.At the same time,the comprehensive performance of the operation strategy proposed in this paper reaches 29.66%,which is much higher than the electric load following strategy and heat load following strategy.Compared with the traditional operation strategy,the proposed operation strategy has the best comprehensive performance,which verifies the feasibility and superiority of the proposed operation strategy.
