PMU-based Real-time Load Balancing Strategy for Lights-out Case in India – A Case Study

Power management informed consumers to lights-out nine minutes as a challenge for the darkness of the Corona-virus, across India. The absence of commercial operations and a substantial difference between demand and supply could contribute to a power outage. Accurate and reliable measures are taken to overcome these differences in demand and supply. This phenomenal rapid decrease in load and quick restoration must be done with water and gas resources. Real-time Wide-area monitoring and smart automation (WAMSA) technologies measure and control these irregular instances and power grid variables. Wide area monitoring system (WAMS) is an integrated PMU-based frequency and voltage stabilization system. It helps to assess the reactive power deficit of the weaker regions and estimate the critical situations. It identifies voltage stability conditions for specific power generation. The novelty of this paper is to present the new real-time load shedding and grid balancing strategy by using PMUs potential functions and practices. This case study creates awareness among power engineers to avoid future blackouts worldwide.
