Transactive control of fast-acting demand response based on thermostatic loads in real-time retail electricity markets

Coordinated operation of distributed thermostatic loads such as heat pumps and air conditioners can reduce energy costs and prevents grid congestion, while maintaining room temperatures in the comfort range set by consumers. This paper furthers efforts towards enabling thermostatically controlled loads (TCLs) to participate in real-time retail electricity markets under a transactive control paradigm. An agent-based approach is used to develop an effective and low complexity demand response control scheme for TCLs. The proposed scheme adjusts aggregated thermostatic loads according to real-time grid conditions under both heating and cooling modes. A case study is presented showing the method reduces consumer electricity costs by over 10% compared to uncoordinated operation. (C) 2017 Elsevier Ltd. All rights reserved.
