Deviation settlement mechanism based real-time energy assessment system for open access user

India being a vast country has many industries and it had been a major challenge for these industries to purchase power at lower cost. Introduction to Electricity Act (open access) has made possible for these industries to purchase power at lower cost. In India, Indian energy exchange (IEX) and power exchange India limited (PXIL) are the two apex bodies that follow open access guidelines for collective transactions and act as an intermediary between producer and the consumer and helps in transmission of electricity using load dispatch centers (LDC). The inter-state and intra-state bilateral transactions of open access are handled by regional LDC and state LDC respectively as per central electricity regulatory commission (CERC) and state electricity regulatory commission (SERC) open access regulations. Since the electricity cannot be preserved economically equity between generation and consumption must be maintained, this is the major challenge faced by the LDC. In another side, open access users are paying hefty penalties as per deviation settlement mechanism, since proper real-time monitoring and control system not available at their end. This paper presents demand side management solution for open access users with help of wireless sensor networks technology. This solution helps the open access users to avoid penalties and helps to get incentives by suggesting timely needful actions; this, in turn, helps to maintain grid stability.
