Impact of Thermostatically Controlled Loads and Non-Linearities on Frequency Regulation of Power-Grid

This research investigates the impact of thermostatically controlled loads (TCLs) on frequency regulation within power-grids, crucial for sustainable energy management. With the transition to renewable energy sources (RES), maintaining frequency stability becomes challenging due to their inherent variability. Power-grids, incorporating various energy sources and loads, offer a solution, but efficient load distribution is vital. The study focuses on sensitivity analysis, exploring how varying generator inertia affects the response of a system with the different load sharing between Power-grid and TCL with GDB (Governor dead band) and GRC (Generation rate constraint) with effect of non-linearity. Through innovative modeling, including dynamic representations of inverter air conditioners (IAC), the study enhances understanding of TCL interaction with power-grid dynamics. The research conducts load sharing experiments and sensitivity analysis, revealing insights into frequency regulation.
