Compensation Point Configuration Method of Static Var Generator Based on Clustering Algorithm

In three-phase unbalanced management, static var generator (SVG) can be used as a current source to compensate unbalanced load and reduce three-phase unbalanced node voltage. Reasonable configuration of SVG compensation points can not only improve the governance effect of three-phase imbalance, but also reduce the investment cost. Aiming at the problem of reasonable configuration of SVG compensation points, this paper proposes a negative sequence current based clustering algorithm to determine SVG compensation points, and establishes a mathematical model to solve the compensation capacity of SVG with the objective of negative sequence voltage, network loss and minimum investment cost. The feasibility and economy of the proposed method are verified by IEEE33-bus simulation.
