Optimization of electrically driven heat pump heating system for heat stations
In order to solve the insufficient heating capacity of heating stations caused by heat source shortage,and to avoid the high cost of a primary heating network transformation,an electric heat pump heating scheme is proposed by taking a heating station of a residential community as an example.Based on the TRNSYS,a simulation model of the electric heat pump heating system is established.The bi-level optimization model is used to optimize the capacity design and operation scheme of the main equipment with the goal of optimal life cycle economy.Finally,the marketing potentiality of the system is evaluated from the perspectives of economy and impact on the power grid.The results show that the present value of the total investment in the life cycle of the electric heat pump heating system is positive,indicating that the system has good economy.In addition,the seasonal imbalance coefficient of the power grid increased by 13.4%after the adoption of this system,which increased the power utilization rate.
