Conference Proceeding by ASHRAE, 2020



We describe initial research to evaluate the potential of connected lighting systems (CLS) to provide gridservices. We develop a model for CLS, using a set of parameters to represent operation behaviors andconstraints: maximum power, minimum power, nominal power, ramp rate, and time delay. Parameter values a regenerated for representative CLS. Lighting-power demand curves are constructed, indirectly capturing building-occupant preferences for lighting as functions of electricity price. The CLS model and the demand curves are incorporated into a transactive control platform to simulate CLS providing grid services. Previous research has shown transactive control (TC) tobe a powerful tool to enable end uses to provide gridservices through a hybrid economic-control approach. Initial quantitative results are provided for CLS in amedium commercial office building to show the amountof demand reduction and the associated energy savings.
