Abstract: In order to promote the consumption of new energy and the construction of multi-energy complementary new energy base for solar, wind and pumped storage, and solve the problem of rational capacity configuration of pumped storage and new energy, the development conditions and scale of wind power and solar power are deeply analyzed.Under the condition of the unknown installed scale of pumped storage, wind power, photovoltaic and the capacity of new energy directly power transmission, a bi-level planning of association complementary operation system model is constructed and a solve loop is proposed.The upper-level model determines the capacity configuration scheme of pumped storage, wind power and photovoltaic based on the principle of maximizing the scale of multi-energy complementary new energy base.The lower-level model aims to minimize the output fluctuation of the association power generation, and output a stable output process to improve the safety and reliability of the grid as much as possible, solveing the problems of instability, the difficulty of peak regulation and frequency control, and power limiting caused by intermittent power supply connecting to the grid.The effectiveness of the model and algorithm is verified by taking the new energy of Shigatse City and Xianghe pumped storage station as examples.The results show that the constructed bi-level planning model is scientifically proposed.The capacity configuration is Xianghe pumping storage station with installed capacity of 1 800 MW and new energy development scale of 5 700 MW(wind power 2 000 MW,photovoltaic 3 700 MW),which improves the grid-connected conditions of wind power and photovoltaic, achieveing stable power delivery.
