Power System with Advanced Adiabatic Compressed Air Energy Storage Power Station Energy and Reserve Markets Jointly Optimize the Clearing Model

Energy storage is an effective measure to achieve large-scale wind power consumption, and advanced adiabatic compressed air energy storage (AA-CAES) technology is considered to be one of the most promising large-scale energy storage technologies with wide application scenario. In this paper, AA-CAES power station is taken as an important means to absorb wind power. Combined with the rules of the power market, the joint optimal clearing model of the day-ahead energy and reserve market of the power system with AA-CAES power station is established. This model not only considers the uncertainty of wind power and bidding, but also fully considers the complex nonlinear coupling relationship among power, pressure, flow and temperature in AA-CAES system, which can realize the maximum consumption of wind power while making the system run optimistically and economically. The effectiveness and practicability of the proposed model are verified by example analysis, and the economy of system operation and wind power absorption rate are improved effectively.
