考虑EV/住宅综合需求响应的CCHP两阶段协同优化
Two-stage Co-optimization of CCHP Considering Integrated Demand Response of EV/Residence
摘要
Abstract
This paper investigates the demand response and energy supply system planning,and proposes a two-stage co-optimization model considering electric vehicle(EV),residence and multi-generation system.In the first stage,a demand response model of EV is established to achieve optimal dispatch between EV and residence and realize the optimization objectives of minimizing charging and discharging costs and the variance of EV-residence superimposed load.In the second stage,a residential combined cooling,heating and power system integrated with multiple renewable energy sources,including solar and geothermal energy,is constructed to establish a demand response model for residence with electric,heating and cooling loads,with the optimization objectives of minimizing the system comprehensive operating cost and CO2 emissions,to achieve the optimal scheduling between residence and system.Taking a residential district in Changsha as an example,the effectiveness of the proposed model is verified by comparing the optimization performances of different scenarios on typical days in winter and summer.The results show that charging and discharging costs are reduced by 36.7%and 68.5%on typical days scenario 4 in winter and summer,EV and residence superimposed load variance is decreased by 82.7%and 59.0%,system comprehensive operating costs are reduced by 8.1%and 14.7%,and system CO2 emissions are decreased by 11.3%and 15.4%,which are significantly better than other scenarios.In addition,the reliability of a multi-generation system under extreme weather is further verified,and overall optimization performances decrease with the increasing number of EV.关键词
