Virtual Inertia Enhancement using DC-Link Capacitors in Wind Integrated Power Plants

Whenever a power plant reaches generation failure, inertia is the key aspect that maintains the frequency stability of the plant. The adaption of Renewable Energy Sources and their corresponding power generation methods have reduced the inertia feature of the present-day power plants. As the trend of ameliorating to renewable energy sources is escalating gradually, it has become the need of hour to develop proficient techniques for enhancing inertia. This research emphasizes the efficacy of inertia enhancement techniques, like DC Link capacitors, which produce virtual inertia and operate as a storage system. Furthermore, Simulink models validate that the amalgamation of semiconductors, such as DC Link capacitors promises an ameliorated stability of power system by stabilizing the frequency response which marks this methodology as a reasonable and productive approach for future wind integrated power plants.
