Our civilization, dependent on fossil fuels, has a peculiarity, namely a centralized and deterministic character of the energy system. The highly centralized nature means the overall energy control in a small number of institutions, of which depends the welfare of much of humankind. The commitment of many scientists and engineers and many other...

Este artículo se centra en los temas relacionados con la operación óptima de las microrredes, que son conjuntos de cargas, generadores y sistemas de almacenamiento de energía, aislados o conectados al resto de la red eléctrica, que pueden ser gestionados de manera coordinada para suministrar electricidad de forma fiable. Se aborda la...

In this paper, a Model Predictive Control (MPC) approach is proposed to manage a grid-tied hydrogen microgrid (μG) . The μG testbed is equipped with a 1-kW polymer electrolyte membrane (PEM) electrolyzer and a 1.5-kW PEM fuel cell as main equipment. In particular, we present a formulation that includes the cost of the electricity...

As microgrids gain reputation, nations are making decisions towards a new energetic paradigm where the centralized model is being abandoned in favor of a more sophisticated, reliable, environmentally friendly and decentralized one. The implementation of such sophisticated systems drive to find out new control techniques that make the system...

In this paper, a performance comparison among three well-known stochastic model predictive control approaches, namely, multi-scenario, tree-based, and chance-constrained model predictive control is presented. To this end, three predictive controllers have been designed and implemented in a real renewable-hydrogen-based microgrid....

The present paper describes the work being done by INTA and University of Seville – AICIA in the framework of a joint research project in the field of Proton Exchange Membrane Fuel Cells (PEMFC). The main objective of the project is to develop a novel methodology for the characterization and investigation of fuel cell stacks, that...

In 2006, HERCULES Project was launched with two objectives. First, design and build the first hydrogen refuelling station at South of Spain, in Seville province. Hydrogen will be produced via an electrolyser connected to a Photovoltaic Field. Second, change internal combustion engine of a SUV vehicle into an electric engine fed using a PEM Fuel...

Nowadays, problems associated with greenhouse gases emission and fuel ending, makes that renewable energy sources and hydrogen technology have high interest for governments and researchers, and become an option for an environmentaly sustainable world. Renewable energy sources, like solar energy and wind energy, have been used for the last three...
