Coordinated Configuration Strategy of Grid-forming Stations and Synchronous Condensers for Renewable Energy Bases in Gobi Desert and Other Arid Areas
摘要
Abstract
The development of renewable energy bases in desert,Gobi and desertification land has given a strong push to the low-carbon transition of power systems.However,due to the lack of synchronous power source on site,these bases are characterized by low inertia and low short-circuit ratio.The reasonable configuration of grid-forming stations and condensers can effectively improve the inertia and voltage characteristics of the bases,but the existing research often focuses on only one of the two characteristics.Therefore,a coordinated configuration strategy of grid-forming stations and synchronous condensers considering both inertia and voltage support is proposed in this paper.First,the supporting capability mechanism of the grid-forming station and the synchronous condenser and the configuration relationship between them are analyzed.Then,based on the reactive power support coefficient,the priority order of grid-forming station reconstruction is built,and the preliminary configuration scheme of the grid-forming station is determined according to the order to meet the system inertia demand.Further,the synchronous condensers are configured to satisfy the constraint of the short-circuit ratio of multiple renewable energy stations,and the preliminary scheme is modified considering the inertia support provided by condensers.The configuration that maximizes the support capability of grid-forming stations and synchronous condensers is achieved eventually.Finally,the effectiveness of the proposed strategy is verified by the simulation with a renewable energy base located in the Gobi Desert and other arid areas in Northwest China which lacks the support of synchronous power source.关键词
