摘　　要：将液气压缩空气储能用在"自发自用,余电上网"模式的光伏发电系统中,提出了一种能量管理策略,优化储能的充放电和电网的交换功率,建立以日收益最大为目标函数的模型,求解储能的最优容量。最后通过算例分析经济效益,和铅酸蓄电池进行比较,表明液气CAES更具经济性优势,随着技术的改进和性能的完善,经济性将更加明显,是一种具有投资前景的储能方式。This paper proposes a new energy management strategy for the application of the hydro-pneumatic CAES to photovoltaic power generation system based on the principle of self-sufficient power generation with the surplus going to the grid. This strategy was used to optimize the charge and discharge of energy storage and the grid＇s exchanging power. And also a model was set using the maximum daily profits as the objective function to calculate the optimal capacity. Finally,its economic benefits were calculated using examples and then compared with those of lead-acid batteries. It was found that the hydro-pneumatic CAES was a better energy storage form with more economic advantages. Moreover,with the development of technology and improvement of performance,the hydro-pneumatic CAES will have good commercial prospects because of its increasing economical efficiency.
