BIDDING STRATEGY AND OPTIMAL DISPATCHING METHOD OF WIND-HYDROGEN COUPLING SYSTEM PARTICIPATING IN SPOT MARKET
In order to solve the problems of weak bidding ability and difficult market accommodation in high proportion wind power market,a bi-level Stackelberg game model of high proportion wind power coupled hydrogen energy storage system participating in spot market bidding is proposed.Firstly,the internal energy conversion relationship of the wind-hydrogen coupling system is studied,and the energy"time-space translation"mechanism of the wind-hydrogen coupling system is revealed.Considering the benefits of the wind-hydrogen coupling system and the cost of wind curtailment,the wind power bidding and hydrogen energy storage charging and discharging decision models are established.Secondly,taking into account the interests of wind-hydrogen coupling system and independent system operators,a market clearing model with thermal power units and wind-hydrogen coupling system as the main body is established based on Stackelberg game.Finally,aiming at the difficulty of solving the two-layer model,the KKT(Karush-Kuhu-Tucker)condition and strong duality theory are used to transform the bi-level model into a single-level mixed integer programming model which is easy to be solved.The simulation results show that the proposed strategy has played a positive role in the market consumption of high proportion of wind power.
