Abstract:

The smart grid is a modern power grid that achieves high efficiency and robustness based on sophisticated information and communications technologies. Demand response has great potential in helping balance demand and supply in a smart grid, cutting peak generation capacity and hence electricity generation cost. Arguably, auctions represent the most natural and efficient approach for carrying out demand response between the power grid and large electricity users, microgrids, and electricity storage devices. This talk is about how demand response auctions can be mathematically modelled and designed, and how far can the performance limits be pushed, in terms of bid expressiveness, truthful information revelation, computational efficiency, and economic efficiency. In particular, we will present a demand response auction that is truthful, runs in polynomial time, and achieves (1+epsilon)-optimal social cost for any arbitrarily small constant epsilon. The key technique lies in the marriage of smoothed analysis and randomized algorithm/mechanism design, which may have a broad range of applications in other mechanisms design problems where social welfare maximization is hard (NP-hard) but not too hard (admits a smoothed polynomial time algorithm).
