Development of a Strategy for the choice of PVG installations in the Radial Distribution System
industrial electrical power systems
Distributed generation (DG) is the only option for the electricity sector, as an effective alternative for electricity supply instead of the traditional centralized power generation. In this paper PV Generation (PVG) is considered as a Distributed Generation, installed at different nodes of the radial distribution feeders. The Power Utilities are beginning to acknowledge PVG as an economically viable alternative to deferring investment at generation, transmission and distribution levels, meeting demand growth and reducing the power loss and improving the voltage profile, thereby improving the distribution network performance and security. The benefits of installing of the PVG in a node in the radial feeder vary widely. Therefore, appropriate siting and sizing of PVGs could lead to many positive effects for the distribution system concerned. This paper presents a simple methodology to develop a strategy for deciding upon the location and the size of the PVG for installation in the radial distribution feeders. For this purpose, a 400V radial distribution system from the Kanchipuram district in Tamil Nadu is taken for testing the methodology proposed and to present a guiding chart developed for the Distribution system personnel.
