Distributed control approach for community energy management systems in presence of storage

In this paper we present a system architecture and suitable control methodologies for the management and control of Distributed Generation (DG) units, Renewable Energy Resources (RES), Active Demand (AD) and storage units, being these Electric Vehicles (EV) or Uninterruptible Power Supply (UPS). Within the proposed platform, control methodologies allow to adapt unit generation profiles and active loads to ensure economic benefits to each actor. The key aspect is the organization in two levels of control: at residential level a Smart Home Controller (SHC) monitors and controls smart appliances while at higher level a Community Energy Management System (CEMS) coordinates generation units, negotiates consumption with SHCs and sets power grid energy withdrawals. Proposed control methodologies involve the solution of a Walrasian market equilibrium and the design of a distributed solution of a dynamic programming problem.
