VAr compensation by sequential quadratic programming

This paper presents an application of the sequential quadratic programming method to find the optimal sizing of shunt capacitors and/or passive filters for maximizing the net present value resulting from energy-loss reduction while taking investment cost into account and complying with the IEEE-519 standard. The proposed methodology allows the simultaneous solving for fixed and switched volt ampere reactive (VAr) compensators by considering a characteristic load variation curve for each linear and nonlinear load.
