Distributed Generation (DG) can help in reducing the

\r\ncost of electricity to the costumer, relieve network congestion and

\r\nprovide environmentally friendly energy close to load centers. Its

\r\ncapacity is also scalable and it provides voltage support at distribution

\r\nlevel. Hence, DG placement and penetration level is an important

\r\nproblem for both the utility and DG owner. DG allocation and capacity

\r\ndetermination is a nonlinear optimization problem. The objective

\r\nfunction of this problem is the minimization of the total loss of the

\r\ndistribution system. Also high levels of penetration of DG are a new

\r\nchallenge for traditional electric power systems. This paper presents a

\r\nnew methodology for the optimal placement of DG and penetration

\r\nlevel of DG in distribution system based on General Algebraic

\r\nModeling System (GAMS) and Genetic Algorithm (GA).<\/p>\r\n","references":"[1] H.L. Willis and W.G.
