考虑频率稳定约束的分布式调相机选址定容策略
Location and Sizing Strategy of Distributed Condensers Considering Frequency Stability Constraints
摘要
Abstract
The proposal of the"dual carbon"goal has accelerated the integration of new energy generation represented by wind and solar power into the grid.The grid connection of new energy generation with a high proportion of power electronic interfaces will weaken the inertia support capacity and prominent frequency stability problems in the power system.Distributed synchronous condensers serve as rotating components in wind and solar power stations,providing voltage support and rotational inertia to the system,thereby enhancing the frequency support strength of the power grid.However,an efficient and feasible configuration method for distributed condensers must be developed.This paper proposes a distributed condenser location and sizing method that considers frequency stability constraints.Node inertia is used to evaluate the system inertia distribution,identify weak areas of the system frequency support,and select the condenser configuration location.Considering critical inertia as an inequality constraint,a distributed condenser location and sizing strategy is designed with the optimization goal of minimizing the configuration capacity.Based on the analysis of numerical examples,it is shown that the distributed condenser location and capacity determination strategy proposed in this paper is direct and efficient and can more effectively improve the system frequency support strength while minimizing the total configuration capacity of the condenser.关键词
