Abstract: Aiming at problems such as the low efficiency of renewable energy conversion and the single energy flow mode, this paper proposes a heat pump energy storage system combining cold, heat and power generation to achieve the purpose of diversified utilization of renewable energy. The system is suitable for buildings requiring cooling, heating/domestic hot water production and electricity. This paper mainly uses MATLAB for numerical calculations, selects several key cycle parameters to calculate and analyze the thermodynamic performance of the system, and uses the genetic algorithm and TOPSIS decision method to carry out fine design of the system working conditions. Through the multi-objective optimization calculation and the optimal solution, the system can achieve a total energy efficiency of 2.39 and a high thermal economic performance, indicating that the system can achieve the goals of cooling, heating water and power supply and providing ideas for the application of the multiple energy storage system.
