Energy management considering demand response resource in commercial building with chiller system and energy storage systems

Abstract

One of the promising contributions from end-users such as commercial buildings (CBs), residences and/or factories is demand response (DR) in which the end-users reduce their electricity consumption upon a request from the utility. In CBs, consumption is reduced by fully or partially shutting down the chiller systems used in heating, ventilation and/or air conditioning (HVAC) loads. On the other hand, an energy storage system (ESS) which has been used for further improvements in energy and economic efficiencies and supply reliability also has a potential as a contributor for DR. Based on this background, this paper proposes an energy management algorithm for chiller system and ESSs considering the participations to Korean demand response resources market. Uncertainties in temperature and DR requirements are also considered as scenarios in the proposed method. The validity of the proposed method is ascertained through case studies.
