Query: Optimal Power Procurement and Demand Response with Quality-of-Usage
  Guarantees   In this paper, we propose a general operating scheme which allows the utility
company to jointly perform power procurement and demand response so as to
maximize the social welfare. Our model takes into consideration the effect of
the renewable energy and the multi-stage feature of the power procurement
process. It also enables the utility company to provide quality-of-usage (QoU)
guarantee to the power consumers, which ensures that the average power usage
level meets the target value for each user. To maximize the social welfare, we
develop a low-complexity algorithm called the \emph{welfare maximization
algorithm} (WMA), which performs joint power procurement and dynamic pricing.
WMA is constructed based on a two-timescale Lyapunov optimization technique. We
prove that WMA achieves a close-to-optimal utility and ensures that the QoU
requirement is met with bounded deficit. WMA can be implemented in a
distributed manner and is robust with respect to system dynamics uncertainty.
