Abstract:

The subject of this semester thesis is modeling and control of a large population of thermostatically controlled loads, such as air conditioners and fridges. The goal of the research is using thermostatically controlled loads for demand side management (DSM) in the electricity network. DSM aims at reducing power consumption during peak periods, to avoid upgrades in the power generation and distribution infrastructure. The response of the power consumption of a large population of air conditioners to an o set in temperature set point of the thermostat is simulated. A second order linear time-invariant model that describes these dynamics is identi ed. The accuracy of this model over a range of input signals is evaluated. Finally, an optimization-based controller for tracking a reference power consumption is proposed, simulated and compared to an internal model control structure. i
