This paper utilizes the application of Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) techniques to find the most appropriate locations of Unified Power Flow Controller (UPFC) with optimum cost of generation for loadability limit and minimum active power loss, while satisfying the power system constraints. Two objective functions are taken as the indexes of the system performance:...

Distribution network is an essential part of electric power system, which however has higher losses than transmission system. directly affect the operational cost Therefore, loss reduction in distribution very important for system users and connected customers. One commonly used ways reducing reconfiguration (DSR). In this process, configuration changes by opening closing sectional tie switches...

Optimal reactive power dispatch (ORPD) problem is an important problem in the operation of power systems. It is a nonlinear and mixed integer programming problem, which determines optimal values for control parameters of reactive power producers to optimize specific objective functions while satisfying several technical constraints. In this paper, stochastic multi-objective ORPD (SMO-ORPD) prob...

This paper reviews and compares the performance of reactive power dispatch strategies for the loss minimization of Doubly Fed Induction Generator (DFIG)-based Wind Farms (WFs). Twelve possible combinations of three WF level reactive power dispatch strategies and four Wind Turbine (WT) level reactive power control strategies are investigated. All of the combined strategies are formulated based o...

This paper deals with the problem of optimal reconfiguration medium voltage distribution networks by proposing a mixed-integer nonlinear programming (MINLP) model. optimization model has as objective function minimization total power losses in all branches network constrained active and reactive balance equations, regulation bounds device capabilities, among others. The proposed MINLP formulati...

This paper presents an optimal controller in order to achieve trajectory tracking for nonlinear systems and minimization of a quadratic cost functional. The synthesized optimal control law comes from solving the Hamilton-JacobiBellman equation for state-dependent coefficient factorized nonlinear systems. The proposed control scheme is applied for the Boost power converter. Power converters are ...
