The need for energy, especially electricity is increasing along with the development of technology. An increase in electrical load and location powerplant far causes voltage drops power line losses. One solution can be chosen by adding a distributed generation (DG) to distribution network. This study aims enhance profile reduce losses based on optimal placement capacity DG-based photovoltaic (P...

As Distribution Systems are growing large and being stretched too far, electric utilities and end users of electric power are becoming increasingly concerned about meeting the growing electric demand. Hence efforts have been made by electric utilities to reduce the losses in the distribution system. In this dissertation work, Network Reconfiguration and Optimal Distributed Generation placement ...

This paper has developed a novel multiobjective function for optimal sizing and sitting ofDistributed Generation (DG) units and capacitor banks in simultaneous mode to improve reliabilityand reduce energy losses. The proposed function consists of four objectives: Cost of Energy NotSupplied (CENS), System Average Interruption Duration Index (SAIDI), costs of energy loss andinvestment. A novel st...

abstract: in this paper a control scheme for grid-connected operation mode and the island state of distributed generation is presented. in normal conditions, every inverter dg system in micro-grids to supply a preset power, normally operate in a constant current control mode. when micro-grids removed from the network, dg inverter of each system must recognize the island and change position to v...

this paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. the hybrid dc power sources are connected to grid using power electronic converters include dc-dc converter and grid connected voltage source inverter. the power from hybrid power sources is controlled during voltage sag by designing of control strategy for dc-dc converter....
