【 摘 要 】

Integration and coordinated operation of renewable energy sources (RESs) offer to conventional consumers the possibility to control energy production and consumption in order to obtain technical and economic benefits. In this work, a mixed-integer linear programming approach is proposed to model and optimize DC-coupled grid-tied microgrids. The objective is to reduce industrial consumer electricity bill and energy storage systems degradation, considering operational constraints and rules defined by a complex binomial differentiated tariff and net metering policies to exchange energy. A novel model is developed to DC-coupling integration considering the efficiency of power transformation process and elements with two possible power flow conditions. An original formulation based on logical constraints is also proposed to model the net metering policies and to find the best compensation energy strategy for solving the optimization problem. A case study of a Brazilian industrial consumer, owner of a real-world DC grid-tied microgrid, is presented. The proposed approach involves low-cost procedures that can be integrated into a commercial solution to optimize microgrids in similar net metering contexts, encouraging the use of RESs in developing countries.
