RESEARCH ON ADVANCED CONTROL STRATEGY OF WIND HYDROGEN COUPLING SYSTEM

Aiming at the problems of insufficient tracking accuracy of planned wind farm output, weak energy storage system regulation, large output power fluctuations, this paper proposes an advanced control strategy for the wind-hydrogen coupling system. Based on the state of the hydrogen storage system, the ultra-short-term power forecasting and the day ahead power forecasting, formulate a system adjustment strategy, propose the objective function of maximizing the planned output tracking ability, maximizing the energy storage system adjustment ability, and minimizing the power fluctuation smooth weighting, using algorithm performs point-by-point scroll optimization on the output parameters to achieve the effective improvement of the planned output tracking ability of the wind-hydrogen coupling system. The advanced control strategy proposed can reduce the error between the actual output of the system and the output plan, maintain the effective adjustment capacity of the hydrogen energy storage system, and reduce the average power fluctuation of the system, which has a good application prospect.
