Performance evaluation of Northern Regional Transmission System of India: Critical Analysis for Grid Resilience

The resilience of electricity grids is of utmost importance to ensure uninterrupted electricity supply and sustain the functionality of critical infrastructure and essential services. This paper presents a comprehensive evaluation of the resilience of the Northern Regional Transmission Grid of India for the year 2022. The study assesses the grid’s ability to withstand and recover from various challenges, including extreme weather events, equipment failures, overloading. The evaluation of northern grid resilience involves the analysis of multiple factors, including frequency of outages, response time to disruptions, impact of outages and voltage control through reactor operations and AC line opening. To conduct the assessment, historical outage records, and other related data have been utilized. The study underscores the importance of investing in robust grid infrastructure, network upgrades, proactive maintenance practices, and modernization initiatives, advanced technologies to strengthen the resilience of power grids and ensure uninterrupted transfer of power.
