Dynamic and Distributed Online Convex Optimization for Demand Response of Commercial Buildings

Abstract: 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 with respect to the time horizon 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 respon… Show more

“…Theoretical work focuses on the control and optimization of flexible consumption; the objective can focus on carbon, electricity costs, or grid stability (or some combination, as in [24]) without significant difference in the theoretical treatment. Example of theoretical frameworks for flexible load include control methods [25] using linear time-invariant control systems [26], a Markov decision process with deferrable loads [27], decentralized control [28], and distributed dynamic online convex optimization [29]. These methodologies are applied to a variety of load types, including electric vehicle charging [30], grid-connected battery storage [31], [32], and thermostats [33]- [35].…”

“…Example 1 (Power grids). In the context of power grids, (2) may capture a demand response task [13], [14] or a realtime optimal power flow problem [11]. In this case, x in are the power setpoints of distributed energy resources, w t is a vector of powers consumed by uncontrollable loads, and y t may represent the total power as y t = 1 x in + 1 w t and/or voltage magnitudes (one can also compute the matrix A t based on a linearized AC model).…”

“…The theoretical and algorithmic endeavors are motivated by a number of problems arising in power systems [11], [13], [14], autonomous vehicles [15], [16], charging of electric vehicles [17], and human-aware robot systems [18], just to name a few. While Section II will explain some examples, we stress here that an accurate model of the comfort/satisfaction level of users is typically unknown, and it may vary not only across individuals, but also for the same individual [7], [8].…”

“…Distributed convex optimization has received a great deal of interest in recent years due to its widespread practical applications in many fields [1–8]. Compared with centralized optimization, distributed optimization has an essential difference in that the full knowledge of the overall problem structure need not to be known in advance.…”
