含混合储能的综合能源系统协同优化与低碳策略OA

Multi-energy coupling and efficient conversion can improve the utilization efficiency of various energy sources.This paper proposes an integrated energy system consisting of a reversible solid oxide cell(RSOC),a hybrid energy storage system,and combined cooling,heating and power(CCHP).Firstly,electric,heat and cold energy storage are introduced into the system as short-term energy storage units,and RSOC and CCHP are combined with hydrogen/methane storage tanks to realize long-term energy storage.Secondly,the output characteristics of renewable energy and load characteristics in different seasons are analyzed,and the operation strategy of the energy storage system is optimized.Then,technical and economic analysis is carried out for five typical scenarios,and the operation influences of the hybrid energy storage system,CCHP,and RSOC are discussed.Finally,the impact of carbon trading mechanism parameters on the planned capacity of energy storage and system cost is investigated.The simulation results show that the proposed model achieves high installed capacity of renewable energy and a lower energy abandonment rate,with both low-carbon performance and economic efficiency.
