Flexibility based Coordination Framework For Three-Level Energy Management System

With the increasing penetration level of distributed energy resources (DERs), prosumers play a vital role in demand-side management. The prosumers with DER provide flexible services to the system operFator. This work proposes a novel three-level energy management system coordination framework in which prosumers provide upward and downward flexibility to the system operation. The system operates then runs the global optimization of the whole system with the flexibility request to the prosumer. The suggested methodology considers the conflicting techno-economic objectives of the system operator and prosumers. To evaluate the proposed method, we compare two scenarios that are, without flexibility, and with flexibility. Results show that our proposed strategy improves the voltage profiles and reduces power losses, power generation costs, and peak demands from the system operator’s perspective.
