Optimal Allocation of Distributed Power Supply Based on Improved Gygis Alba algorithm

Reasonable planning and allocation of distributed generation (DG) access to the distribution network can improve the system voltage stability while taking into account the interests of operators and users. In this paper, considering the economic indicators and system voltage stability, a multi-objective optimization model is established, and the weights of each objective function are determined using hierarchical analysis, which is then transformed into a single-objective function planning problem. Aiming at the shortcomings of Gygis Alba algorithm with strong global search ability and weak local search ability, a novel and improved Gygis Alba algorithm is proposed. The mutation idea of genetic algorithm is incorporated into it for the optimal configuration of DG, which improves the convergence ability and convergence accuracy. The improved Bai Xuan Gou algorithm is verified to have better stability and practicability through the arithmetic examples, and the established model has good practical significance.
