Output variability and low generating inertia associated with solar and wind electric power generation resources increase the requirement of grid-scale ancillary service capacity and add strain to existing firm generators that provide these services. Buildings consume the majority of electricity in the United States and can play a significant role in helping to meet these challenges by using their HVAC systems as a link to thermal energy storage. However, predicting a building's ancillary service demand response performance continues to be a challenge, particularly for complex multi-zone systems, such as the variable air volume. A dynamic model of a representative variable air volume system was developed and simulated to investigate the response of the system to implementation of four common demand response strategies over a range of cooling loads and implementation intensities: zone air dry-bulb temperature adjustment, duct static pressure adjustment, supply air temperature adjustment, and chilled water temperature adjustment. Curves are presented that map power reduction as a function of cooling load and implementation intensity on a 10-min spinning reserve timescale. A study of these maps along with simulated data reveal that terminal unit damper position is a significant determining factor of performance effectiveness for each strategy.
