Market-based Control of Air-Conditioning Loads with Switching Constraints for Providing Ancillary Services
Air-conditioning loads (ACLs) are among the most promising demand side
resources for their thermal storage capacity and fast response potential. This
paper adopts the principle of market-based control (MBC) for the ACLs to
participate in the ancillary services. The MBC method is suitable for the
control of distributed ACLs because it can satisfy diversified requirements,
reduce the communication bandwidth and protect users' privacy. The modified
bidding and clearing strategies proposed in this paper makes it possible to
adjust the switching frequency and strictly satisfy the lockout time constraint
for mechanical wear reduction and device protection, without increasing the
communication traffic and computational cost of the control center. The
performance of the ACL cluster in two typical ancillary services is studied to
demonstrate the effect of the proposed method. The case studies also
investigate how the control parameters affect the response performance, comfort
level and switching frequency.Comment: 5 pages, conferenc
