Compressed Air Energy Storage in Wind Solar Complementary Systems

Renewable energy resources are abundant and developing rapidly in the power industry. This article establishes a wind-solar energy storage hybrid power generation system and analyzes the coordinated operation of energy systems in multiple scenarios. In a multi-scenario energy environment, the hybrid wind-solar energy storage system, driven by wind and solar energy, uses compressed air as energy storage equipment and a cold water tank as an intermediate regulating element, which can absorb heat and improve compressor efficiency. Considering system operation and equipment constraints, a multi-objective optimization model was established to reasonably calculate and allocate wind energy on compressed trains and solar energy on extended trains, in order to achieve the goal of minimizing system costs and maximizing profits. The simulation results indicate that this analysis has inspiration in practical engineering applications and can provide reference value for the coordinated operation of multi-energy power supply systems.
