HYBRID WIND-HYDROGEN GRID-CONNECTED CONTROL CONSIDERING ENERGY STORAGE RESPONSE
In response to the response delay problem in the consumption of wind power by electrolytic cells and fuel cells,construction of wind turbine,electrolyzer,fuel cell,battery,and superconducting magnetic energy storage coupled to a DC bus,Time scale characteristics based on energy storage response,the fast response of superconducting magnetic energy storage is used to supplement the power deficit caused by the delayed response of electrolytic cells or fuel cells and batteries,development of a grid-connected control strategy,divides the system into 20 working modes,ensure real-time consistency between feed-in power and load dispatch curve,consider the dynamic response characteristics of the battery model extraction of key elements of the dynamic change process,based on battery application scenarios,simplification to obtain a multi-timescale model of the battery.Model building in PSCAD/EMTDC,four simulations verify the effectiveness of grid-connected control.The results show that equipping superconducting magnetic energy storage can fully mitigate the response delay and improve energy utilization.
