Multi-Objective Optimization of Reactive Power for Grid-Connected Photovoltaic Power Plants Based on Improved Bee Colony Algorithm

With the increasing awareness of social environment and energy, the development of distributed photovoltaics are receiving more and more attention. To solve the voltage limit violation caused by photovoltaic access system, a optimization model of reactive power compensation location based on improved bee colony algorithm is proposed. Aiming at the weak local search mechanism of artificial bee colony algorithm, chaotic mapping and cross algorithm are introduced to improve the operation speed and ensure the balanced distribution of solution set. Finally, a photovoltaic power station in Shandong Province is taken as the research object, and the feasibility and effectiveness of the method are verified.
