Keywords: Active power conditioner Optimal placement Discrete firefly algorithm Power quality a b s t r a c t This paper presents an improved solution for optimal placement and sizing of active power conditioner (APC) to enhance power quality in distribution systems using the improved discrete firefly algorithm (IDFA). A multi-objective optimization problem(More)
This paper presents a dynamic PQ analysis on the effects of high-penetrated grid-connected photovoltaic (PV) systems in a distribution system under different weather conditions. To track practical considerations, all information on PV units and weather conditions given in this paper were collected from different solar panel producers and from the Malaysian(More)
Conventional distribution systems are normally radial fed by a downstream feeder. In the past, protective system was designed based on being radial. In recent years, the use of distributed generation power plants has been developed. If these power plants are to be connected to global networks, they would influence protective system of distribution networks(More)
Nowadays using of new energies in the form of dispersed resources in the worlds is wide spreading. In this article we will design a dispersed production source in the form of a solar/wind hybrid power plant in order to supply the energy of a residential unit according to a sample load pattern based on evolutionary algorithms such as GSA and PSO algorithms(More)
— Optimal capacitor allocation in distribution systems has been studied for a long times. It is an optimization problem which has an objective to define the optimal sizes and locations ofcapacitors to be installed.This paper presents a new methodology using particle swarm optimization (PSO) Algorithm for the placement of capacitors on the distribution(More)
This study presents a method to determine the optimal number and placement of power quality monitors (PQMs) in power systems by using genetic algorithm (GA) and Mallow's Cp which is a statistical criterion for selecting among many alternative subset regressions. This procedure helps to avoid the dependency of set voltage sag threshold values of PQMs in the(More)
Efficient project execution is an objective in many industries, and existing project management research gives direction about how project team factors influence two important capital project outcomes: time and cost. In addition, use of electronic collaboration (E-collaboration) technologies is essential for supporting projects. Combining a literature(More)
The research in this paper seeks ways for manufacturing companies to accomplish projects in real time with less cost. This paper describes a new model using critical success factors of implementing projects in small-and medium-sized enterprises (SMEs). The factors in the conceptual model were identified in past studies and are validated from interviews with(More)
