Distributed generation (DG) has emerged as a key issue for the sustainable development in near future. In the literature, many researchers were introducing about DG placement considering various criteria. These DGs can be of conventional and renewable energy sources (RESs). Under these circumstances, if only wind energy based DG would be placed at the appropriate locations in the particular region of the network. In this situation, high noise will be created in those regions. To overcome this problem, it is necessary to allocate some other energy sources in those regions. From these points of view, system operators and policy makers to deal with such impact in the restructured electricity market to identify the adoptable and unadoptable DGs based on technical, economical, environmental and resource availability aspects has been discussed.
