Dynamic and Distributed Online Convex Optimization for Demand Response of Commercial Buildings
share
We extend the regret analysis of the online distributed weighted dual averaging (DWDA) algorithm[1] to the dynamic setting and provide the tightest dynamic regret bound known to date for a distributed online convex optimization (OCO) algorithm. Our bound is linear in the cumulative difference between consecutive optima and does not depend explicitly on the time horizon. We use dynamic-online DWDA (D-ODWDA) and formulate a performance-guaranteed distributed online demand response approach for heating, ventilation, and air-conditioning (HVAC) systems of commercial buildings. We show the performance of our approach for fast timescale demand response in numerical simulations and obtain demand response decisions that closely reproduce the centralized optimal ones.
