Coordinated Configuration Strategy of Grid-forming Stations and Synchronous Condensers in Renewable Energy Base Considering Short-circuit Ratio Constraints
摘要
Abstract
Renewable energy bases in the Gobi Desert and other arid areas are often geographically remote,and the system is characterized by low inertia and low short-circuit ratio.To improve the short-circuit ratio of the renewable energy base,this paper first analyzes the control principle of grid-forming stations based on the virtual synchronous generator control.Compared with the support capability of the grid-following station and the synchronous generator,the grid-forming operation capability of the grid-forming station is further quantified,and the operation cost of the grid-forming station is analyzed.Based on the definition of multi-infeed short-circuit ratio,this paper proposes a method for calculating the multi-infeed short-circuit ratio of the renewable energy base containing grid-forming stations,and constructs the sensitivity index of short-circuit ratio for grid-forming stations,to determine the configuration priority order for grid-forming stations.Then,a coordinated configuration strategy of grid-forming stations and synchronous condensers is designed.Finally,an actual renewable energy base that lacks the support of the synchronous power supply is taken as a case to verify the effectiveness of the proposed configuration strategy.关键词
