Reduction of losses and improvement in voltage profile for a 2.8 MVA distribution network with Dispersed Generation

The major issues always attached to conventional electrical Distribution Systems are poor voltage regulation so far the consumers are concerned and the high level of losses & limited or no reserve capacity of the Network so far as the utility is concerned. In this paper, an attempt has been made to address both issues by adding Dispersed Generation of appropriate capacity at appropriate location, using a methodology developed and described here. The study on a 2.8 MVA Radial Distribution Network having low voltage problem and high losses has been conducted and the results are found encouraging. For this purpose, the Network was simulated for obtaining existing status of voltage profile and losses and thereafter similar study was carried out by adding Renewable Distributed Generation. The analyses of results clearly show that there is no low voltage problem in any section of the Network, with a considerable reduction in losses. Incidentally, the reserve capacity of the Network is also increased giving a scope for future expansion.
