Optimal Configuration of Hydrogen Energy Storage for Wind and Solar Power Stations Considering Electricity-Hydrogen Coupling Under Carbon Neutrality Vision
Due to the fluctuation and intermittence of new energy output, its direct access to the grid will affect the safe and stable operation of the power system. In order to promote renewable energy consumption, developing hydrogen storage system coupled with electricity and hydrogen is an effective way. For this reason, aiming at the optimal configuration of hydrogen storage capacity of new energy power station at the power generation side, a multi-objective optimal configuration model of hydrogen energy storage is established with the minimum investment cost of hydrogen energy storage, the minimum system cumulative tracking plan error and the maximum increment of carbon dioxide emission reduction as the objective function, and the abandonment rate and the actual site area as the constraints. The model is solved by the combination of genetic algorithm with elitist strategy and entropy weight method. Finally, the effectiveness of the proposed model and algorithm is verified by a case study in Gansu Province, China. The results show that the optimal number of 200 kW electrolytic cells, 6 kg hydrogen storage tanks and 200 kW fuel cells are 268, 291 and 222, respectively. The hydrogen storage system can actively respond to the dispatching command and greatly reduce the power abandonment rate.
