Optimal placement of distributed generator for maximun load allowability and reduced losses mitigating congestion of transmission system

With fast technological development in the field of electrical, electronics and software technologies the usage of electrical power is escalating at a faster rate, stressing the generation and transmission system. In order to have continuous supply, Distributed Generators (DG) are positioned at distribution systems meeting growing energy demands. DG increases the economic efficiency in addition to peak shaving. DG also has lower rates of greenhouse emissions and high energy security with optimum penetration and location. In this paper, optimum location of DG has been determined using two main factors viz. critical loading parameter and benefit index. Benefit index comprises of Voltage Profile Improvement Index (VPII) and Line Loss Reduction Index (LLRI).DG location has a crucial role in reduction of transmission and distribution losses, avoidance of up gradation of transmission and distributed infrastructure along with support, relieving distributed network congestion and providing ancillary services.
