Abstract

Under the "carbon peak and carbon neutrality" strategy, optimal energy storage system configuration in new-energy stations is vital for grid stability and economic benefits. Energy storage systems have wide applications and great potential in the power system and will be more important in the future grid. Under market conditions, determining the optimal energy-storage configuration scale for new-energy stations while improving new-energy consumption and ensuring station returns is urgent. Aiming at the deficiencies of existing models in market-fluctuation response and complex-constraint fusion, this paper constructs a two-layer optimal configuration model for deep coupling of energy-storage capacity, charge-discharge strategies, and the market environment. By introducing the linkage between electricity-spot-market simulation and energy-storage investment decision-making and using optimization tools like the particle-swarm optimization algorithm, multi-scenario simulations of energy-storage key parameters are carried out considering power balance, policy constraints, and price fluctuations. Simulation results show that the optimized configuration can significantly increase new-energy consumption (reduce wind-and-solar curtailment by 15%-20%) and boost the station's annual revenue by 12%-18% through peak-valley arbitrage. The charging-and-discharging strategy balancing economy and stability proposed in the research offers scientific decision support for new-energy station planning.
