Plant-level electricity demand response for combined manufacturing system and heating, venting, and air-conditioning (HVAC) system

Electricity demand response plays a critical role in reducing energy consumption, power demand, carbon footprints, and energy cost for manufacturers. The top two energy consumers in a typical manufacturing plant are the manufacturing system and the heating, venting, and air-conditioning (HVAC) system. Traditionally, studies regarding electricity demand response for these two systems have been conducted separately. In this paper, an integrated electricity demand response model for the combined manufacturing and HVAC system is proposed to advance the state-of-the-art of the electricity demand response from the manufacturing system level to the entire plant level. The production capability, electricity pricing, power limitation, and ambient temperature are considered in the integrated model to identify an optimal demand response strategy with respect to both production schedule and HVAC control. A numerical case study is used to illustrate the effectiveness of the proposed integrated model. (C) 2016 Elsevier Ltd. All rights reserved.
