Power System Virtual Inertia Implemented by Thermostatically Controlled Loads

EasyChair Preprint 805

Abstract

Thermostatically controlled loads (TCLs) (e.g. air conditioners) have large potentials for providing ancillary services to power systems. In this paper, an approach to implementing power system virtual inertia by TCLs is proposed, while maintaining customers’ comfort levels. Considering the TCLs’ own unique power consumption fluctuation and response uncertainty, a tracking control strategy based on PI controller is proposed to preserve the performance of power system virtual inertia. Some simulation results are provided to verify the effectiveness of the control scheme.

Keyphrases: Thermostatically controlled loads, direct load control, frequency regulation, tracking control, virtual inertia
