Abstract:

Mechanical pump energy storage systems play a crucial role in modern energy management, particularly in enhancing energy storage efficiency and optimizing the use of renewable energy sources. This paper presents an in-depth analysis of the working principles and thermodynamic models of mechanical pump energy storage systems, revealing the key factors that influence system efficiency. It proposes strategies for screening based on operational characteristics and designing thermodynamic processes, thereby improving performance during both compression and expansion stages. The paper also addresses system integration and the optimization of thermal energy management pathways. The goal is to enhance the overall performance of mechanical pump energy storage systems, promote their application in renewable energy and smart grid contexts, and provide robust support for the widespread adoption of clean energy.

Key words: mechanical pump energy storage, thermodynamic optimization, cycle efficiency, energy management
