A novel optimization-based method for solving systems of nonlinear equations is proposed. The method employs Invasive Weed Optimization (IWO) for solving nonlinear systems and can find all real and complex roots of a system and also detect multiplicity. The proposed solver consists of two parts: a twophase root-finder that detects the solutions of a system(More)
Voltage stability is one of the most challenging concerns that power utilities are confronted with, and this paper proposes a voltage control scheme based on Model Predictive Control (MPC) to overcome this kind of instability. Voltage instability has a close relation with the adequacy of reactive power and the response of Under Load Tap Changers (ULTCs) to(More)
