Optimal Reactive Power Compensation in Power System Considering SVC

This paper introduces a method for optimal reactive power compensation considering SVC. Static load margin of each node is calculated and then sorted to determine the location of reactive power compensation. To know the optimal compensating capacity, the mathematical model of fuzzy multi-objective is established, and it can be solved by the primal-dual interior point algorithm. The proposed method is applied to a grid of Northwest China with satisfactory results.
