Multi-Objective Voltage Regulation Method for Active Distribution Network Considering Load Static Characteristics
To mitigate the adverse effects of large-scale distributed generation on the voltage of distribution network, this paper proposes a multi-objective voltage control method under the active distribution scheme. With considering the load static characteristics of active distribution system, this paper analyzes the impact of load characteristics on the active distribution system operation. Further, this paper constructs the voltage control model to minimize the clean energy curtailment, the voltage profile derivation, and the active power losses, with taking the active power output of distribution generation and grid-connected voltage as decision-making object and considering the distribution network security operation constraint. Then, this paper uses the improved parallel multi-objective differential evolution algorithm to solve the model. Base on the simulation carried out on the modified IEEE-33 bus test system, the effectiveness of the proposed model and algorithm is demonstrated, and the impact of load static characteristics on the voltage regulation is discussed.
