Multi-objective Voltage Balance Control Method for Distribution Network Based on Active Tabu Search

During the implementation of voltage balance control in the distribution network, due to the lack of analysis of the relationship between parameters during the operation phase of the distribution network, the average voltage deviation is relatively large. Therefore, an active Tabu search based multi-objective voltage balance control method for distribution networks is proposed. Based on the minimization of the ratio of short-circuit voltage to the corresponding switch breaking capacity in the power grid, an objective function stage for voltage balance in the distribution network was constructed, and constraints for the objective function were set from the perspectives of radial topology and power flow. In the voltage balance control phase, the active Tabu search algorithm is introduced to set the distribution network target adjustment parameters as random initialization parameters in the solution space. Analyze the correlation of parameters at different operating stages by using the cost function values of target adjustment parameters in the neighboring distribution network. Finally, use the parameter corresponding to the minimum cost function value as the previous distribution network target adjustment parameter. Control the voltage balance of the distribution network. In the test results, the design method has good voltage control performance under dual objective, three objective, and four objective conditions, and the corresponding average voltage deviation is at a relatively low level.
