Power management strategy for solving power dispatch problems in MicroGrid for residential applications

This paper proposes a new method to manage the daily operation of MicroGrid (MG) for residential applications. Thorough discussion and simulations are conducted to clarify and highlight the principle of the method. Nonlinear optimization problem formulation is also performed. The proposed cost function takes into consideration the costs of the emissions NOx, SO₂, and CO₂ as well as the operation and maintenance costs. The microgrid considered in this paper consists of wind turbine, micro turbine, diesel generator, photovoltaic array and fuel cell. The Mesh Adaptive Direct Search (MADS) is employed to minimize the cost function of the system while constraining it to meet the costumer demand and safety of the system. Finally, a comparative investigation aiming at assessing the efficiency and applicability of the method is carried out. The method is proven simple and remarkably fast.
