Modeling And Simulation Of Non-Supplementary Compressed Air Energy Storage System

The wind power and solar power generation in our country are limited by the grid side. In the new energy,the region has a serious abandoned wind, abandoned light phenomenon,resulting in a lot of economic losses,but also reduces the investment enthusiasm of renewable energy,which limits the large-scale development of renewable energy in China. And energy storage device is the key to solve the bottleneck problem,and the energy storage device can achieve the function of cutting peak and fill valley,so that the output power of renewable energy can be smooth,and the acceptance rate of renewable energy can be improved.Energy storage device is a key equipment in the micro grid,which plays a decisive role in the play of the advantages of micro grid.Non-Supplementary compressed air energy storage can have zero pollutant discharge,low power generation cost,suitable for long-term energy storage,long discharge time,and large capacity,suitable for the construction of distributed generation system with different levels.In the context of large-scale development of solar and wind energy and environmental protection,the non- Supplementary compressed air energy storage system is the best choice to solve the serious problem of the development of renewable energy.In this paper, the bottleneck problem of the development of renewable energy and the function of energy storage device in micro grid are discussed, and compared and analyzed the performance parameters of various energy storage devices. The working flow of the non- Supplementary compressed air energy storage system is studied, and the system is decomposed and analyzed. The energy storage and release levels of the system are designed and calculated, obtained the optimum parameters of the system. Based on the idea of modular modeling, we built the mathematical model of each module in the system, and compiled corresponding C++ algorithm. Based on STAR-90 simulation support platform, we put the algorithm into storage, and each module is connected to the system's working process. Through simulation and debugging, the system works in the best parameters, and obtained the whole range of the working process of the non 10 MW compressed air storage system. In the simulation support system, the software of REFPROP is called, which can improve the accuracy and precision of the thermal parameters.
