Resumo

This paper presents the solution to Environmental/economic Dispatch for a microgrid system operating connected to main grid with diesel, microturbine, energy storage, wind and photovoltaic power plants. This problem has nonlinear functions with equality constraints and inequality as well be dynamic and time dependent. The objective function take into account the operation and maintenance costs of generators, diesel generators power curve, state of charge constraints for batteries, and includes wind and photovoltaic generation. The Pattern Search algorithm is used to solve the problem to minimize the total system costs. Computer simulations shows the application and effectiveness of proposed methodology.
