PROJECT TITLE :
Contingency-Type Reserve Leveraged Through Aggregated Thermostatically-Controlled Loads—Part I: Characterization and Control
There are few systematic methodologies capable of predicting and leveraging the reserve capability potential of enormous populations of thermostatically-controlled hundreds (TCLs). For such reserves to own economic and technical worth, it is essential that demand-aspect flexibility aggregators and system operators be in a position to try to to so quickly and robustly. Also, aggregators would like to make sure TCL users' comfort and end use satisfaction. Part I of this two-part paper introduces an analytical approach to characterize and management the statistical bounds on the potential aggregated response of a population of TCLs, while making certain users' comfort satisfaction. First, the uncertainty related to the instantaneous power consumption of a typical TCL is described by a group of random variables and their statistics. TCL statistics are then used to characterize the exploitable flexibility from a massive population of similar devices. From this, a control strategy and parameters are introduced for sporadic (i.e., contingency-sort) reserve provision by the population. In Half II, the proposed analytical approach and management strategy are validated for the special case of electric water heaters (EWHs). More, the trade-off between demand response capability and EWH users' comfort satisfaction is investigated through many case studies.
