Energy Management for Demand Responsive Users with Shared Energy Storage System

This paper investigates the energy management problem for multiple self-interested users, each with renewable energy generation as well as both the fixed and controllable loads, that all share a common energy storage system (ESS). The self-interested users are willing to sell/buy energy to/from the shared ESS if they can achieve lower energy costs compared to the case of no energy trading while preserving their privacy e.g. sharing only limited information with a central controller. Under this setup, we propose an iterative algorithm by which the central controller coordinates the charging/discharging values to/from the shared ESS by all users such that their individual energy costs reduce at the same time. For performance benchmark, the case of cooperative users that all belong to the same entity is considered, where they share all the required information with the central controller so as to minimize their total energy cost. Finally, the effectiveness of our proposed algorithm in simultaneously reducing users' energy costs is shown via simulations based on realistic system data of California, US.
