Many developing countries have focused on the technology of distributed generation (DG) for the planning of expansion of the generation. Planning and sensible choice attributes are dictated by the circumstances. the optimal placement of DG using genetic algorithm (GA) is conducted in order to minimize losses and & t improve voltage profile at load buses. In addition, the optimal level of penetration has worked, that consists of OPF compositions in order to minimize the total cost of the operation.DG is also important when the geographic limit price (LMP) on the basis of the market. If the LMPs are available on all hosts, these price signals can be effectively used to accommodate DG. This concept has been applied to the calibration and the DG at standard market design (SMD) frame (usually adopted in the United States) to 30 bus and IEEE MATPOWER 118 bus-bar systems. Developing countries like India, also encourage managers to bridge the gap in supply and demand. Research of three real-life practical systems have been conducted to show the viability of the DG at various reasons. First offers the vitality of the DG internal Availability based tariff (ABT) mode, where Abt the pricing mechanism is connected frequency energy, adopted at the second India quantitative improvement in steady state the device after enabling wind generation at the site in the State of Maharashtra, India.The third and last show the reliability of the distribution system (from Mumbai, India), after you have enabled DG. While conventional planning and system studies to justify the viability of technologies, D.g., just consider these aspects may not be sufficient for the typical multiple Attribute decision making (MADM) problems. Thus, the preliminary feasibility studies and some of the advanced planning techniques were used to come to grips with the full terms of scheduling problems. Central to all advance planning is to build a common platform on which the utility function can be evaluated using the normalized values for all attributes. The attributes described in the technique of MADM are capital costs, energy is not served in a year, and profit from injecting power to the grid at peak times, all of which are important for a developing country. Uncertain futures are considered three possible conditions of loading, which can be low, medium and high. Various scenarios (plans) are generated by different combinations of configurations. DG can be configured in stand-alone mode, hybrid mode, or in the mode of formation of micro-mesh with or without connection to the power grid. With the increased complexity in the DG planning along with several attributes, which will be taken into account, more sophisticated methods than conventional economic analysis necessary to come to correct decisions, decision makers. Analytical hierarchy process (AHP) is used to obtain the relative weights in the objective sense. In addition, statistical method, as an interval based technology MADM with compromise is used to a short list of real plans and identify the most suitable plan. He suggested using the weight obtained from AXA to find productivity in Envelopment Analysis (DEA) for appraisal system of sample plans obtained by reference to the rural electrification scheme in India. evaluation plans are presented and discussed. The comparative advantages and disadvantages of the methods are reported on the basis of the results obtained.
