Due to the inherent intermittency and instability of renewable energy such as wind and solar energy, the power generated by these two kinds of renewable energy power plants also has intermittent and unstable problems, resulting in a large number of "abandonment and abandonment of light" problems. Compressed-air energy storage systems can "spliced" intermittent renewable energy to make up for the shortcomings of poor continuous operation and unstable power output of renewable energy power plants, so as to finally achieve stable output and provide large-scale use of renewable energy Effective solution. In order to further understand the coupled characteristics of renewable energy sources such as wind energy and solar energy with compressed air energy storage systems, the Energy Storage R & D Center of CAS Institute of Engineering Thermophysics relies on the research and development and demonstration of "key megawatt-class physical energy storage key technologies" And the repair project "Comprehensive Measurement and Testing Platform for Large-Scale Energy Storage Technology", proposed and constructed a renewable energy simulation system to simulate the actual instability of renewable energy, and study the coupling characteristics of renewable energy and compressed air energy storage system . Research on renewable energy simulation system mainly focuses on the testing and testing of compressed air energy storage control system. Based on the power output characteristics of renewable energy power plants, a set of reasonable energy simulation and operation control system is established to enable energy storage system to exert its own efficiency The energy storage function, to maximize the joint operation of the economic and technological benefits. The principle shown in Figure 1, that the use of analog systems in the laboratory to reproduce the voltage / frequency fluctuations, intermittent power supply and other typical renewable energy power grid real operating environment for the energy storage system. At the same time, according to the calculation result of grid load and compressor power difference, compressor load is controlled by compressor controller and inverter in real time to realize the storage and utilization of unstable power. At present, the renewable energy simulation system has completed the construction of 1.5MW advanced compressed air energy storage system integrated experiment platform in the energy storage R & D center, reached the design targets and has carried out relevant experimental research work.
