Reversible heat pump-organic Rankine cycle (HP-ORC) system is a kind of prospective energy storage technology, which can store the surplus electricity and waste heat recovery simultaneously and realize a high round-trip efficiency even beyond 100%. However, the comprehensive evaluation of energy, exergy and economic performance of HP-ORC are still not enough as a novel system, hindering the deep understanding and further development and application. This study will first select proper candidate working fluids based on theoretical analysis of the thermophysical properties and operating characteristics of HP-ORC system. Then effects of different combinations of crucial parameters in HP-ORC system are evaluated on the energy, exergy and economic performance. Finally, multi-objective optimization will be conducted to analyze the optimal performance of HP-ORC system under designed parameters. The optimization results indicate that R245ca is the optimal working fluid among all the investigated working fluids. Under the optimal parameters, the exergy destruction during the discharging cycle accounts for 68.23% during the reversible operating process, which is significantly greater than that of the charging cycle. In the discharging cycle, the top three exergy destruction are successively taken by the evaporation process, expansion process and condensation process cycle, and the corresponding proportions are 26.81, 21.67% and 19.54% respectively.

可逆热泵-有机朗肯循环（HP-ORC）系统是一种具有前瞻性的储能技术，可同时存储剩余电能和余热回收，实现高达100%以上的往返效率。然而，作为一个新颖的系统，HP-ORC的能量、火用和经济性能的综合评价还不够，阻碍了深入理解和进一步的开发和应用。本研究将首先基于对HP-ORC系统热物理性质和运行特性的理论分析，选择合适的候选工质。然后评估HP-ORC系统中关键参数的不同组合对能量、火用和经济性能的影响。最后，将进行多目标优化，分析HP-ORC系统在设计参数下的最优性能。优化结果表明，R245ca是所有研究工作流体中的最佳工作流体。在最优参数下，可逆运行过程中放电循环的火用破坏占68.23%，显着大于充电循环。在放电循环中，前三位的火用破坏依次为蒸发过程、膨胀过程和冷凝过程循环，对应比例分别为26.81、21.67%和19.54%。在最优参数下，可逆运行过程中放电循环的火用破坏占68.23%，显着大于充电循环。在放电循环中，前三位的火用破坏依次为蒸发过程、膨胀过程和冷凝过程循环，对应比例分别为26.81、21.67%和19.54%。在最优参数下，可逆运行过程中放电循环的火用破坏占68.23%，显着大于充电循环。在放电循环中，前三位的火用破坏依次为蒸发过程、膨胀过程和冷凝过程循环，对应比例分别为26.81、21.67%和19.54%。
