Photovoltaic Hosting Capacity Evaluation of Distribution Networks and Inverter Parameters Optimization Based on Node Voltage Sensitivity
摘要
Abstract
With large-scale distributed photovoltaic (PV) integrated into distribution networks, the reasonable evaluation method on PV hosting capacity of distribution networks has become current research hotspot. A stochastic scenario simulation method based on node voltage sensitivity was proposed to assess PV accommodation of distribution system. The typical scenario was selected according to PV penetration level at each sequential hour, and a pseudo-normal distribution sampling technique was employed to improve the stochastic simulation efficiency. Reactive power regulation capability of inverter can be utilized to compress overvoltage caused by PV accession. The Volt/Var 6-point control mode was applied to realize local voltage control. The inverter parameters optimization was determined by standard particle swarm optimization with the objective of minimum voltage deviation and reactive regulation. The IEEE 33-bus test system was established in OpenDSS platform, and the case study results indicate that the proposed method is effective and feasible.关键词
