چکیده

In developing countries, where the utilities already facing the problem of high power losses and poor voltage profiles because of high loads, DG can be the key answer to solve these questions while expansion and reinforcement of these systems to meet the increasing load demand are faced by economical and environmental difficulties. An evaluation of some technical benefits of integration of DG into MV distribution networks are presented in this paper. An efficient methodology for integration of DG units for meeting the increased load demand is also introduced. Kurzfassung— In Entwicklungsländern, wo die Netzbetreibern, die bereits dem Problem von hohen Energieverlusten und schlechten Spannungshaltung wegen hoher Lasten gegenüberstehen, kann DE die Schlüsselantwort sein, um diese Fragen zu lösen, während Vergrößerung und Verstärkung dieser Systeme, um die zunehmende elektrischer Bedarf zu befriedigen, durch wirtschaftliche und Umweltschwierigkeiten gegenüberstehen. Eine Einschätzung von einigen technischen Vorteilen der Integration von DE in MS Verteilnetze wird in dieser Arbeit präsentiert. Eine effiziente Methodik für die Integration von DE, um den erhöhenden elektrischen Bedarf zu befriedigen, wird auch eingeführt.

Analysis and Comparison of Load Flow Methods for Distribution Networks Considering Distributed Generation

Conventional passive distribution networks are changing to modern active distribution networks which are not radial. Conventional load flow methods should be modified for new distribution networks analysis. In modern distribution networks distributed generation (DG) units are embedded with conventional and/or renewable resources. DG units are generally modeled as PV or PQ nodes which inject ...

A New Method of Distribution Marginal Price Calculation in Distribution Networks by Considering the Effect of Distributed Generations Location on Network Loss

The determination of practical and coherent policy to pin down the price in restructured distribution networks should be considered as a momentous topic. The present paper introduces a new method of distribution marginal price (DMP) calculation. The main aim of this paper is to evaluate the DMP for both producers and consumers separately. For this purpose, the first part of the procedure emphas...
