Multi-Objective Reactive Power Optimization Method for the Distribution Grid with Distributed Generator

<div class="section abstract"><div class="htmlview paragraph">To enhance the economic efficiency and operational security of distribution grids, this paper develops a reactive power optimization model that incorporates distributed power sources. The model aims to minimize the costs of reactive-load compensation equipment, reduce voltage deviations, and lower network losses while satisfying operational constraints. To overcome the common drawbacks of the standard genetic algorithm—suc
