Enhanced Grid Frequency Stabilization with Renewable Energy and Virtual Inertia Support

The virtual inertia control (VIC) methodology is presented in the given work for frequency regulation in interconnected test microgrid system. As power grids inertia deteriorated due to intermittent renewable energy sources. Therefore, it is required for operating reserved power plants to overcome voltage and frequency instability. The short-term suitable inertia control approach can alleviate this issue. Test area 1 includes the wind turbine generator, biogas plant, and biodiesel plant, while test area 2 contains the solar photovoltaic, biogas plant, and biodiesel plant along with VIC in each area. For the analysed micro-grid model, a modified type-II Fuzzy controller is proposed. A Quasi-Opposition based Harris Hawks Optimization (QOHHO) has been employed to optimal tune the various gains of deployed controllers. The improved system dynamic performance reveals the efficacy of the suggested VIC mechanism. The supremacy of the recommended regulation strategy is supported by the distinct improved outcomes.
