This study investigates the typical configuration mode and optimal allocation method for photovoltaic (PV), wind generator and energy storage (ES) in Microgrid system. Firstly, the six typical scenarios of the hybrid integration modes are discussed. By considering the objectives of minimum PV-Wind-ES investment cost, minimal expectation of energy not supplied (EENS) and minimal line loss, the p...

In this paper optimum size and location of capacitors and distributed generations (DGs) are determined simultaneously in a radial distribution network. The objective function includes power losses reduction and voltage profile improvement using ant colony algorithm. Allocation capacitors and of DGs should be carefully determined with the consideration of different planning incentives. It shows ...

Voltage regulation (VR) is a procedure to keep voltages in a distribution network (DN) within normal limits. Conventionally, a voltage regulator can read voltage levels from predefined measures, and regulate the voltages. However, due to lacking of a distributed generator’s (DG) information, the unexpected electricity from a DG will mislead readings on voltages levels, so as to disturb the VR i...

Nowadays, the trend of countries and their electrical sectors moves towards inclusion renewable distributed generators (RDGs) to diminish use fossil fuel based DGs. The solar photovoltaic-based DG (PV-DG) is widely used as a clean sustainable energy resource. Determining best placements ratings PV-DG significant task for systems assess potentials. With capability inverters inject required react...

Distributed Generation (DG) based on Renewable Energy Sources (RES) are considered as an effective and economical technology for the advancement of Electric Power System (EPS) to fulfill load demand. Mostly, studies pertaining DG planning performed while considering constant demand generation. However, these considerations may provide misleading inconsistent values loss reduction, voltage profi...

Voltage instability and power loss are significant problems in distribution Systems (DS). However, these usually mitigated by the optimal integration of distributed generation (DG) units DN. In this regard, location size DGs crucial. Otherwise, System performance will deteriorate. This study is conducted to place radial DS. Mayfly Algorithm (MA) used determine placement minimize loss, increase ...

Single objective constant PQ load models were extensively considered for site and size of distributed generation (DG) shunt capacitor (SC) allocation. Which may lead to single non-dominated solution unpredictable misleading results about their size, loss reduction payback period. Therefore, primary this study is investigate the effects seven nonlinear voltage-dependent siting sizing DG SC consi...

Recently, smart grids have been considered as one of the vital elements in upgrading current power systems to a system with more reliability and efficiency. Distributed generation is necessary for most of these new networks. Indeed, in all cases that DGs are used in distribution systems, protection coordination failures may occur in multiple configurations of smart grids using DGs. In different...
