摘要
In view of the power supply reliability problems caused by the large-scale grid connection of wind power and photovoltaic power, and wind and light abandonment problems, combined with the regulation characteristics of pumped storage, energy storage power plants and electrolytic water hydrogen production, a two-layer optimal dispatching strategy for wind water storage multi energy complementary system is proposed. The upper layer model aims to optimize the capacity configuration of each unit of the system to ensure the reliability of power supply and the level of wind and solar energy consumption, with the objective of optimizing the operating economy of the system throughout its life cycle;The lower level model aims to optimize the economy of the system in each dispatching cycle, and aims to give full play to the peak shaving output of energy storage to achieve economic operation of the system. The model uses KKT condition and Big-M method to transform the two-layer model into a single-layer linear programming problem, and calls CPLEX solver in Matlab to solve it. The results show that the proposed strategy can effectively improve the power supply reliability of the system and the absorption level of wind and solar energy, which verifies the effectiveness of the model. © 2023 Science Press.
