In this paper, solving optimal power flow problem has been investigated by using hybrid particle swarm optimization and Nelder Mead Algorithms. The goal of combining Nelder-Mead (NM) simplex method and particle swarm optimization (PSO) is to integrate their advantages and avoid their disadvantages. NM simplex method is a very efficient local search procedure but its convergence is extremely sen...

Mathematical models representing the behavior of electrical loads are an important part any optimal power flow problem. The current state-of-the-art in unbalanced mostly considers wye-connected, constant loads. However, for applications such as conservation voltage reduction, it is crucial to model how consumption depends on network. This article develops a unified framework handle wide variety...

Abstract Traditionally, power systems have been operated to minimize cost while maintaining reliability. However, extreme weather and demand events can affect traditional thermoelectric generation operations due their reliance on water for cooling. This paper contributes a novel multi-objective formulation of the optimal flow (OPF) problem where cost, withdrawal, consumption are minimized. Thro...

One of the major problem in the optimal operation of the power system is optimal operation of microgrid with regard to the Demand-side-management. From one side, demand-side-management programs  reduce the operating costs of the power system and on the other hand, the implementation of these programs requires a financial incentive policies. In this paper, optimal operation of microgrid with dem...
