Resumen
Integration and coordinated operation of Renewable Energy Sources (RES) and Energy Storage Systems (ESS) offer to prosumers the possibility to control energy production and consumption in order to obtain technical and economic benefits. A novel control algorithm that considers a model predictive control (MPC) and mixed integer linear programming (MILP) approach is proposed in this thesis to optimize the operation of DC coupled grid-tied microgrids. The objective is to reduce industrial and residential consumer electricity bill and Energy Storage Systems degradation, considering operational constraints, rules defined by complex binomial differentiated tariffs and net metering policies to exchange energy. Additionally, a Chance Constrained MPC (CC-MPC) approach is proposed to deal with forecast uncertainties, enhancing the controller performance. A case study of a Brazilian industrial consumer owner of a real-world DC grid-tied microgrid is presented to validate the solution. Experimental validation is carried out in a lab-scale microgrid that simulates the real microgrid. The involved low costs procedures and the obtained results shows the proposed control algorithm as a promised solution that contributes with the development of practical solutions to control microgrids in similar contexts, encouraging the use of Renewable Energy Sources in developing countries.
