A Stackelberg Game for Multi-Period Demand Response Management in the Smart Grid
This paper studies a multi-period demand response management problem in the
smart grid where multiple utility companies compete among themselves. The
user-utility interactions are modeled by a noncooperative game of a Stackelberg
type where the interactions among the utility companies are captured through a
Nash equilibrium. It is shown that this game has a unique Stackelberg
equilibrium at which the utility companies set prices to maximize their
revenues (within a Nash game) while the users respond accordingly to maximize
their utilities subject to their budget constraints. Closed-form expressions
are provided for the corresponding strategies of the users and the utility
companies. It is shown that the multi- period scheme, compared with the
single-period case, provides more incentives for the users to participate in
the game. A necessary and sufficient condition on the minimum budget needed for
a user to participate is provided.Comment: Accepted for Proc. 54th IEEE Conference on Decision and Contro
Energy Management for a User Interactive Smart Community: A Stackelberg Game Approach
This paper studies a three party energy management problem in a user
interactive smart community that consists of a large number of residential
units (RUs) with distributed energy resources (DERs), a shared facility
controller (SFC) and the main grid. A Stackelberg game is formulated to benefit
both the SFC and RUs, in terms of incurred cost and achieved utility
respectively, from their energy trading with each other and the grid. The
properties of the game are studied and it is shown that there exists a unique
Stackelberg equilibrium (SE). A novel algorithm is proposed that can be
implemented in a distributed fashion by both RUs and the SFC to reach the SE.
The convergence of the algorithm is also proven, and shown to always reach the
SE. Numerical examples are used to assess the properties and effectiveness of
the proposed scheme.Comment: 6 pages, 4 figure
