Allocation of UPQC in distribution grids using a hybrid optimisation strategy

In power systems, the Unified Power Quality Conditioner (UPQC) is intended to lessen the voltage drop or rise in the voltage of the source. This research proposes a new technique that integrates the optimisation concept and gives a superior UPQC allocation in distribution grids. The key goal is to allocate a UPQC system in distribution grids at a reasonable cost and lower the losses of the distribution network. Varied linear and nonlinear frameworks of reactive loads are considered to accommodate dissimilar utilisation patterns and estimate demand with the least amount of inaccuracy. A new hybrid approach named Squirrel Search Algorithm Inherited Aquila Optimiser (SSA-AQ) that consolidate the concepts of Squirrel Search Algorithm (SSA) and Aquila Optimisation (AO) is used to select the optimal position of UPQC. As a consequence, the results demonstrate that combining DRPs with UPQC allocation successfully resulted in lower costs and losses.
