A Study on Capacity optimization of Electric-hydrogen Coupling Systems for New Energy Consumption
With an increasing proportion of new energy generation represented by wind and photovoltaic power,the phenomenon of large-scale abandoned electricity is becoming more and more serious.The application of hybrid energy storage technology can effectively help the consumption of wind and solar power,for this reason,therefore,this paper proposes a capacity optimization method for the electric-hydrogen coupled system aimed at new energy utilization.First,the synergistic operation mechanism of electric-hydrogen hybrid energy storage with distributed power sources is described,and a wind and solar power output model is established.Second,integrating economic costs and new energy consumption capacity,a multiple-objective capacity optimization configuration model for electric-hydrogen hybrid energy storage aimed at new energy utilization is established and solved using the NSGA algorithm.Finally,based on a case study of a certain power grid in Qinghai,it is verified that reasonably configuring the capacity of the electric-hydrogen coupled system can effectively improve the economy of the system and better realize the consumption of new energy.
