Placement and optimal size of DG in the distribution network based on nodal pricing reduction with nonlinear load model using the IABC algorithm

The growing use of distributed generation (DG) at the distribution level has led to a change in status networks from passive network an active such as transmission systems. Therefore, pricing method nodal could be used network. DG connection affects bus pricing. If presence reduces losses and congestion network, will also decrease. This paper presents for calculating optimal size place based on planning is done maximize profits companies that have their meet several advantages. simulation was performed using improved artificial bee colony algorithm (IABC). In IABC algorithm, by exchanging received information between bees according Newton gravity laws, it uses all this capacity find ideal answer considering constraints applied system. most placement articles, loads are assumed constant. Because often sensitive voltage frequency, constant load analysis leads inaccurate results. paper, proposed implemented 38-bus radial system with model real frequency system, including residential, commercial, industrial loads.
