Distributed Robust Control of the Power Flows in a Team of Cooperating Microgrids

This brief paper presents a mathematical formulation for a team of cooperating microgrids (TCM) proposing a robust distributed control strategy based on partially nested information. This brief paper faces one of the main problems in a TCM, which is to react to the unpredictable production/demand processes, optimizing power flows, and energy storage in each microgrid (MG). This brief paper focuses on a high-level control of the TCM through properly coordinating power that is exchanged among MGs. The robust distributed control strategy operates in order to minimize the maximum divergence both from an agreed power exchange among MGs and from a technical reference value of the energy storage system of each MG. The proposed approach is based on some quite recent results on robust control for cooperative teams. The robust control approach is tested through a case study.
