A Distributed Algorithm for Dynamic Dispatch of Thermostatically Controlled Loads

According to a survey, heating and cooling loads are major contributors of the total consuming components in residential sector. With increasing demand-supply ratios and deficiency to produce sufficiently, residential loads need to be optimized. Heating/cooling loads comprise mainly of thermostatic control, which are used to manoeuvre operation times of these devices. Operating times and hence power aggregate in turn helps achieve load management targets and thereby serve as ancillary service (AS) to the power grid. In this work, a distributed averaging protocol is used to achieve desired power aggregate set by the utility using steady-state de-synchronization. The model is articulated for homogeneous, heterogeneous as well as population of thermostatically controlled loads and the results are verified using computer program.
