Interruptible load scheme: Demand response management for buildings

Interruptible load scheme has been long established in the National Electricity Market of Singapore (NEMS). However, traditionally only very large industrial consumers participate as interruptible loads. This paper proposes an automated demand response management (DRM) algorithm for buildings to participate as an aggregated load in the interruptible load scheme. The proposed DRM algorithm includes an enhanced multi-parameter based DRM program to reduce the air conditioning system power demand based on the room temperature, human occupancy level, current power demand and curtailment limit as well as a priority-based load shedding DRM program. A computer simulation tool is used to test and evaluate the functionality of the proposed DRM to achieve curtailment limit imposed by interruptible load aggregators.
