due to the increasing interest on renewable sources in recent years, the studies on integration of distributed generation to the power grid have rapidly increased. in order to minimize line losses of power systems, it is crucially important to define the size and location of local generation to be placed. minimizing the losses in the system would bring two types of saving, in real life, one is ...

Distributed generators are beneficial in reducing the losses effectively compared to other methods of loss reduction. On the other hand DGs can be implemented for improvement of reliability of system too. In this paper optimal DG sources placement using Bacterial Foraging Optimization (BFO) is discussed. The optimal size and location of the DG unit is calculated. Reliability and power loss redu...

There is an increasing interest in renewable and green energy sources and the integration of Distributed Generation DG into the power grid system. The problem of optimal capacitor allocation in electric distribution systems involves maximizing energy utilization, feeder loss reduction, and power factor correction. The feeder loss can be separated into two parts based on the active and reactive ...

optimal reactive power dispatch (orpd) is a multi-variable problem with nonlinear constraints and continuous/discrete decision variables. due to the stochastic behavior of loads, the orpd requires a probabilistic mathematical model. in this paper, monte carlo simulation (mcs) is used for modeling of load uncertainties in the orpd problem. the problem is formulated as a nonlinear constrained mul...

Reducing power loss in wireless power receivers is important to avoid thermal design issues. Synchronous rectification is a suitable means for loss reduction. In this paper we propose a synchronous rectifier with a simple control scheme. A detailed analysis leads to a time-domain model which is used to perform a power loss analysis. Experimental verification shows that the predicted efficiency ...

in this article, a multi-objective function for placement of distributed generation (dg) and capacitors with thetap setting of under load tap changer (ultc) transformer is introduced. most of the recent articles have paidless attention to dg, capacitor placement and ultc effects in the distribution network simultaneously. insimulations, a comparison between different modes was carried out with,...
