Abstract: We describe initial research to evaluate the potential of connected lighting systems (CLS) to provide grid services. We develop a model for CLS, using a set of parameters to represent operation behaviors and constraints: maximum power, minimum power, nominal power, ramp rate, and time delay. Parameter values are generated 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) to be a powerful tool to enable end uses to provide grid services through a hybrid economic-control approach. Initial quantitative results are provided for CLS in a medium commercial office building to show the amount of demand reduction and the associated energy savings.
