Due to inherent advantages of DC system over AC system such as compatibility with
renewable energy sources, storage devices and modern loads, Direct Current Microgrid …

As a direct consequence of power systems restructuring on one hand and unprecedented
renewable energy utilization on the other, the uncertainties of power systems are getting …

Abstract Energy Management System (EMS) applications of modern power networks like
microgrids have to respond to a number of stringent challenges due to current energy …

Over the past half-century, Optimal Power Flow (OPF) has become one of the most important
and widely studied nonlinear optimization problems. In general, OPF seeks to optimize the …

The set of optimization problems in electric power systems engineering known collectively
as Optimal Power Flow (OPF) is one of the most practically important and well-researched …

This paper presents a new and efficient method for solving optimal power flow (OPF)
problem in electric power systems. In the proposed approach, artificial bee colony (ABC) …

We consider a network of devices, such as generators, fixed loads, deferrable loads, and
storage devices, each with its own dynamic constraints and objective, connected by AC and …

Given a linear system, we consider the problem of finding a small set of variables to affect
with an input so that the resulting system is controllable. We show that this problem is NP …

An evolutionary programming (EP) based technique has been presented for the optimal
placement of distributed generation (DG) units energized by renewable energy resources …

The optimization of energy consumption, with consequent costs reduction, is one of the main
challenges in present and future smart grids. Of course, this has to occur kee** the living …
