Secondary control with thermostatically controlled loads using MPC based on extended bin state transition model

摘要

This paper deals with providing the secondary control using a large population of thermostatically controlled loads, in particular electrical space heaters. Model predictive control approach is used for control system design. The controller is based on extended 1D bin state transition model, which is designed to be linear parameter varying model in order to include possibility to control the temperature setpoints. Unlike other systems for performing ancillary services, this controller performs two functions simultaneously: secondary control itself and the function of heaters' thermostats. This extended functionality of the controller gives more possibilities for optimization of the population performance. The obtained results show that the designed control system meets the requirements on the secondary control. The proposed ideas can further be used to develop a control system based on 2D bin state transition model that will provide possibility to take into account more accurate dynamics of the second order equivalent thermal parameters model.
