- Model predictive control for microgrid functionalities: review and future challengesPublication . Garcia-Torres, Felix; Cabeza, Ascensión Zafra; Silva, Carlos Santos; Grieu, Stéphane; Darure, Tejaswinee; Estanqueiro, AnaABSTRACT: Renewable generation and energy storage systems are technologies which evoke the future energy paradigm. While these technologies have reached their technological maturity, the way they are integrated and operated in the future smart grids still presents several challenges. Microgrids appear as a key technology to pave the path towards the integration and optimized operation in smart grids. However, the optimization of microgrids considered as a set of subsystems introduces a high degree of complexity in the associated control problem. Model Predictive Control (MPC) is a control methodology which has been satisfactorily applied to solve complex control problems in the industry and also currently it is widely researched and adopted in the research community. This paper reviews the application of MPC to microgrids from the point of view of their main functionalities, describing the design methodology and the main current advances. Finally, challenges and future perspectives of MPC and its applications in microgrids are described and summarized.
- Integration of CCHP microgrids in NZEB with critical loads under high PQR requirements, a position paperPublication . Savariego, Rafael; Moreno-Munoz, Antonio; Abascal-Castaneda, Isabel M.; González-Cuenca, M. Isabel; Silva, Carlos Santos; Tobajas-Blanco, Javier; López-Alcolea, Fco. Javier; Molina-Martínez, Emilio J.; Mannini, Romain; Grieu, Stéphane; Estanqueiro, Ana; Loureiro, DavidABSTRACT: In recent years, many projects have been developed to reduce the energy consumption of buildings, both from the point of view of energy efficiency and the integration of renewable energies. However, few projects are related to the problem of integrating DER in environments dominated by high-tech equipment, the so-called ”critical loads”: data centers, railroad stations, airports, and hospitals. The European Interreg Sudoe IMPROVEMENT project aim is to renovate existing public buildings where critical loads predominate, converting them into nearly zero-energy buildings (NZEB), and for this purpose, it integrates combined cooling, heat, and power (CCHP) microgrid with renewable and other distributed energy resources (DER) like hybrid energy storage systems (ESS). With still one year to go before the end of the project, the consortium partners present in this position paper the latest progress of their respective work packages to date.
