Abstract

Aiming at the problem of frequent voltage fluctuations under the access of large-scale distributed renewable energy and impulsive loads in the port distribution grid, a reactive power optimization strategy for the port distribution grid with power router （PR） and multiple distributed energy sources is proposed. Firstly, based on the analysis of the characteristics of the impulsive load and reactive power control equipment in the port area, a comprehensive model of reactive power optimization with the goal of minimizing grid loss and voltage deviation is established. Then, an improved multi-objective gold rush optimizer （MOGRO） is adopted as the optimization algorithm. Finally, the improved IEEE-33 bus system is used to compare and simulate different algorithms and scenarios, which proves that the improved MOGRO has more advantages, and the port distribution grid with PR has better advantages in reactive power optimization than the port distribution grid with on-load tap changer （OLTC）.
