Estimation of Synchronous and Non-Synchronous Inertia in Renewable Energy Dominated Systems

The thesis addresses some of the issues in the accurate estimation of synchronous and non-synchronous inertia in a renewable energy dominated system. Firstly, accurate estimation of synchronous inertia in a microgrid system with a large share of renewable energy sources is carried out. The work is followed by estimation of non-synchronous inertia in a microgrid system. The next part of the research work classifies the aggregate virtual inertia response from various sources in a system. The last and final research work presented in this thesis deals with estimating both synchronous and non-synchronous inertia in a large power system.
