Situational awareness about weather plays a key role in maintaining load generation balance and operator can use radar image to improve the resiliency in the grid. India is geographically and climatically diverse country. The land areas in the North part of the country have a severe summer conditions that alternates with cold winters. In North India, the rise in temperature is accompanied with strong, gusty, hot and dry winds. These weather conditions coupled with frequent thunderstorms lead to sudden load crash in pockets involving tripping/opening of distribution feeders leading to high voltages in the Northern Grid. Apart from this, Cyclones affect thousands of Indians living in coastal regions. Cyclones leads heavy rains, large storm surges, and strong winds that often cut power supply to the affected areas. In order to increase the resilience of the electricity grid against such onslaught of the weather phenomenon, Doppler Radar Imagery is being used at Control Centres. Six different products have been derived using the data-from Doppler radar. These products help in accessing accurate location of thunderstorms/cyclones, precipitation accumulation, rainfall intensity and wind speed/wind direction. This paper presents the experiences of Grid operator in India to utilising Radar Images and improved the grid resiliency by timely action.
