Demand Response Management for Multiple Utility Companies and Multi-type Users in Smart Grid

Demand Response Management (DRM) improves the reliability and efficiency of the grid by shaping user's electricity load profiles and reducing generation cost, which has been a significant component of smart grid. In this paper, we study the case of DRM with multiple utility companies and multi-type users, where the relationship of utility companies is modeled as a non-cooperative game, and users consisting of residential users, commercial users and industrial users, pay different prices even from the same utility company. We propose a management algorithm to enable the utility companies and users to converge to a stable state in which the balance of power supply and demand is reached.
