基于功率矩准则的分布式光伏承载能力时序可行域解析求解方法
Power-moment-based Analytical Solving Method for Time-series Feasible Region of Distributed PV Hosting Capacity
摘要
Abstract
The feasible region is an essential tool for evaluating the distributed photovoltaic(PV)hosting capacity.How⁃ever,the traditional solving methods such as the convex hull method and point-by-point method are computationally complex and time-consuming.To address these issues,a power-moment-based method for solving the feasible region of distributed PV hosting capacity is proposed.First,the combined effects of PV installation location and capacity on volt⁃age and current in the distribution network are taken into account,the concept of power moment is defined,and a math⁃ematical expression for power moment is given.Second,the constraints of voltage deviation and branch current are in⁃corporated,and an analytical model for the static feasible region of PV hosting capacity of distribution network is estab⁃lished based on the power-moment criterion.Moreover,the time-series characteristics of PV are considered,and a solv⁃ing method for the time-series feasible region(TSFR)of PV hosting capacity is put forward.Finally,a case study on an IEEE 33-bus system verifies the effectiveness of the proposed model and power-moment-based method,indicating that this method can obtain the feasible region of distributed PV hosting capacity quickly and accurately.关键词
