Special Issue Information
Dear Colleagues,
The generation of distributed electricity using micro- and nano-grids is an obvious opportunity to reduce CO2 emissions if hydrogen energy technology is used in addition to renewable energy potential. It is expected that these hybrid microgrids will play an important role in the implementation of the scenario of limiting global warming to 20 C by replacing fossil fuels with renewables.
Thus, to highlight the latest solutions and paradigms in hybrid microgrids, such as vehicle-to-everything (V2X), power-following control, grid-responsive strategies, and global optimization strategies, this Special Issue, titled “Advanced Modeling and Research in Hybrid Microgrid Control and Optimization”, is proposed for Mathematics from MDPI, which is an international peer-reviewed open access covered by many databased such WOS (SCIE Impact Factor 1.747 (2019), Q1) and SCOPUS (Elsevier). The present Special Issue aims to collect innovative solutions and experimental research supported by appropriate modeling and design, as well as state-of-the-art studies, in the following topics:
- Hybrid nano- and micro-grids;
- Hybrid power systems (HPSs);
- Renewable energy sources (RESs);
- Fuel Cell (FC) systems;
- Hybrid energy storage systems (HESSs);
- Smart contracts based on IoT blockchain technology;
- Cyber-security, reliability, maintenance, resilience, and safety in the operation of FC/RES hybrid microgrids;
- Energy management and optimization strategies for FC/RES HPS;
- Control, optimization, and energy management strategies for hybrid/FC/electrical vehicles;
- Vehicle-to-everything (V2X) architectures;
- Communication architectures for microgrids.

Title: Optimising energy management in hybrid microgrids
Authors: Javier Bilbao, Eugenio Bravo, Olatz García, Carolina Rebollar, Concepción Varela

Abstract: This article deals with the optimisation of the operation of microgrids, understood as sets of generators, loads and energy storage systems, which can be isolated or connected to the rest of the electricity grid, and which can be managed in a coordinated manner to supply electricity reliably. Both the problem of controlling the management of load sharing between the different generators and energy storage and possible solutions for the integration of the microgrid into the electricity market will be discussed. Various renewable sources will be considered, such as solar and wind energy, as well as hybrid storage with hydrogen, which allows managing the energy balance on different time scales. Some Machine Learning methods will also be introduced to study the optimisation of microgrids. The conclusions obtained indicate that the development of suitable controllers can facilitate a competitive participation of renewable energies and the integration of microgrids in the electricity system.

Abstract: The general context regarding the integration of electric vehicles within the new concepts of Smart Grid and Smart City, presents the main aspects of the two concepts and the connections between them through new technologies, such as the Internet of Things (IoT) and 5G technology. The concept of smart city considers a number of key elements, such as: economy, citizens (people), government, living conditions (quality of life), environment and last but not least mobility (transport).
Electric vehicles, like energy storage systems along with active management of electricity networks and intelligent automation systems, are parts of what are currently considered future smart electricity networks. The integration of these elements will imply the existence together with the infrastructure of the electricity network and of a communication network.
Regarding the integration of EVs in electricity networks, the electricity consumption due to EV charging is still negligible today. With a widespread adoption of EV, the additional electricity consumption can reach values that will affect the operation of the power system, in a positive or negative way. In fact, if EV charging is unrestricted, the additional consumption of electricity during peak hours can pose problems for the safe operation of the energy system. As a consequence, unrestricted charging of EVs may involve additional investments in electricity generation and transmission capacity, increased wear of distribution network components and electricity quality issues. On the other hand, if EV charging is supported by differentiated tariff systems that take into account the actual production of electricity from renewable energy sources, it can bring many benefits for the operation of energy systems, as well as benefits for reducing pollution and for environment. The article presents the contributions regarding the modeling of loads in electrical networks and the efficiency of clustering techniques in their profiling, and the simulation of the load of medium voltage / low voltage distribution transformers using clustering techniques.
