Predictive control of a renewable energy microgrid with operational cost optimization

A proposal for optimal control of a microgrid powered by solar energy with mixed temporary storage based on a battery bank and hydrogen is presented and evaluated here by means of simulations. The proposal is based on a Predictive Controller that optimizes the operational costs by taking into account the value of the energy generated, the cost of locally storing energy, the aging of the components and the operational constraints. The Constrained Mixed-Integer Predictive Control problem obtained is then solved using a formulation based on the duration of the states, which simplifies the numerical solution. Some simulation results are presented to show the validity of the proposed approach.
