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).
