Economic analysis of newly added cold storage system in an energy station
The central cooling system can improve energy utilization and reduce energy costs through water cold storage,which is one of the main measures for energy conservation and emission reduction of central energy supply stations.Taking an energy station as the research object,a cold storage operation scheme for the central cooling system of the energy station under the time-of-use electricity price was proposed,and the operation strategy under the cold storage condition was simulated,and the energy cost under the current operation strategy and the cold storage operation strategy was calculated.The results show that after the addition of 100 000 RT water cold storage system to the energy station,the peak load of peak shaving and valley filling is 615.2 kWh(about 72%),saving about 5.37 million yuan and 56%of electricity costs per year.Among them,the investment cost of the cold storage tank is about 37.7 million yuan,and the return on investment period is about seven years.The results show that under the time-of-use electricity price mechanism,the peak shaving and valley filling strategy of the water cold storage system can significantly improve the economic benefits of the central cooling system,and provide a reference for the economic operation of the energy station.
