Estimation of Minimum Synchronous Inertia in a Renewable Dominated Power System

Due to high proliferation of wind and PV generation in modern power systems, maintaining adequate synchronous inertia has been a challenging task. Being non-synchronous machines, wind and PV generators cannot provide inherent system inertia to keep system frequency within satisfactory limits during...

Summary:Due to high proliferation of wind and PV generation in modern power systems, maintaining adequate synchronous inertia has been a challenging task. Being non-synchronous machines, wind and PV generators cannot provide inherent system inertia to keep system frequency within satisfactory limits during any contingency such as an interconnection trip or a generator trip. This paper proposes a robust technique for real time estimation of minimum required synchronous inertia subject to desired frequency nadir and ROCOF at a fixed contingency in-between dispatch cycles in a renewable prolific network.
