This paper introduces a proposal of optimized management strategy to control a benchmark grid-connected microgrid consisting of some residential loads, some renewable generators (wind and PV), a genset generator, and a battery storage system. The proposal is to manage the microgrid according to the solution an optimization problem aimed to minimize an economic objective function. Microgrid performance simulations are presented to analyze the goodness of the algorithm when solar power generation is unknown and, therefore, it has to be predicted with the use of real-time measurements and estimation databases.
