Event-Triggered Power Tracking Control of Heterogeneous TCL Populations

This paper presents a study on event-triggered power tracking control of heterogeneous thermostatically controlled load (TCL) populations. The developed schemes are based on continuous-time tracking control of TCL populations of which the aggregated dynamics are described by coupled Fokker-Planck equations. Two event-triggering mechanisms, namely static and dynamic event-triggered control strategies, are proposed, which can guarantee the input-to-state practical stability (ISpS) of the tracking error dynamics while excluding Zeno phenomenon. A simulation study is conducted, and the obtained results show that the developed control strategies can significantly reduce the communication burden while still offering a satisfactory control performance.
