摘要(Abstract):
针对分布式电源承载力线性模型采用内点法求解产生的固有计算误差问题,提出了一种基于改进的综合灵敏度指标的配电网分布式电源最大承载力计算修正方法。建立了计及分布式灵活资源优化调控的分布式电源最大承载力线性优化模型,构建了改进的配电网综合灵敏度指标,并在此基础上提出了分布式电源最大承载力计算修正算法,实现了对分布式电源最大承载力进一步精准计算的同时辨识了系统潜在的薄弱环节。最后在IEEE 33系统验证了所提方法的有效性。
To address inherent calculation inaccuracies in linear models of distributed generation(DG) hosting capacity solved via interior-point methods(IPMs), this paper proposes a calculation revision method for maximum DG hoisting capacity in distribution networks based on enhanced comprehensive sensitivity indices. A linear optimization model is established incorporating optimal control of distributed flexible resources. Then, improved comprehensive sensitivity indices for distribution networks are constructed, and a calculation revision method is subsequently developed to achieve more accurate maximum hosting capacity calculation while identifying potential weak points in the networks. The proposed method is validated on the IEEE 33-bus test system.
