What is STATCOM (Static Synchronous Compensator) ?
STATCOM: A Critical Enabler for Grid Stability in India's Renewable Energy Transition Executive Summary STATCOM (Static Synchronous Compensator) is a power-electronics-based Flexible AC Transmission System (FACTS) device that provides fast and dynamic reactive power support to maintain voltage stability and enhance grid reliability. Compared with traditional Static Var Compensators (SVCs), STATCOMs offer faster response, superior performance under low-voltage conditions, smaller footprint, and greater operational flexibility , making them increasingly preferred by utilities worldwide and in India. India's rapid renewable energy expansion—targeting large-scale solar and wind integration—has increased the need for dynamic voltage support. Consequently, the Central Electricity Authority (CEA), Power Grid Corporation of India (PGCIL), and transmission utilities are deploying STATCOMs across strategic nodes. The technology is becoming a cornerstone of transmission modernization, pa...
