Grid stability concerns intensify at major ISTS renewable hubs
The National Committee on Transmission (NCT) reviewed emerging grid stability issues at its 38th meeting, with GRID-India highlighting persistent and worsening challenges at India’s largest inter-state transmission system (ISTS) connected renewable energy complexes. Low short circuit ratio (SCR) conditions across key locations in Rajasthan and the Western Region are leading to daily oscillations that are increasingly difficult to manage in real-time operations. GRID-India’s assessment identified four distinct types of oscillations affecting the grid. Low-frequency voltage…
