Optimal Allocation of Distributed Generation Against Low Voltage in Distribution Network Based on Particle Swarm Optimization Algorithm

Aiming at the problem of low voltage in rural distribution network, this paper proposes an optimal allocation method of distributed generation against low voltage. Firstly, we establish a sitting and sizing optimization model for distributed generation, which takes the minimum system voltage, the average system voltage deviation and the network loss into consideration. Then the optimization problem is solved by a heuristic algorithm. Finally, the proposed method is simulated and tested on the IEEE-33 bus system, and the results demonstrate that the method proposed in this paper can solve the low voltage problem for each critical node in the distribution network and improve the voltage quality. Hence, the feasibility and effectiveness of the proposed method are verified.
