In recent years, the electric power system is immersed in a process of multiple changes. Thus, the appearance of equipment based on power electronics and its massive introduction in traditionally electric areas (electric drives and applications for transmission and distribution systems), the changes suffered in the basic structure of the electricity business caused by the liberalization of supply, the introduction of a free market of supply and demand, the need to decarbonize electricity production by replacing carbon-based generation sources with renewable generation sources, the appearance of the electric vehicle or the massive application of new technologies of the Information and communication at all levels of the system is causing a revolution in the way electrical systems are planned, managed and operated.
To cope with the changes, two technological solutions based on the development of the network are being considered. On the one hand, the so-called supergrid, consisting of a multiterminal high-voltage direct current (HVDC) network, superimposed on the high-voltage alternating current (HVAC) network. On the other hand, the so-called smart grids or smartgrids, to allow the integration of multiple distributed generation, demand and storage resources, including the electric vehicle, by superimposing a layer of communications on the traditional distribution network that endows it with intelligence and flexibility in its operation.
For this reason, Electrical Engineering, far from being a discipline anchored in the past, is in continuous development, which makes it necessary to have a correct and updated knowledge of all the areas in which it is developed and applied.
Within this strategic sector of electric power, the Research Group on Electric Power Systems (GISEL) focuses its activity on three interrelated lines of research:

• Line 1. Integration of Renewable Energies in the Electric System, FACTS and HVDC.
• Line 2. Microgrids, Electric Vehicle and SmartGrids.
• Line 3. Protection of Electrical Systems.

In addition to the technical objectives of each of the research lines, the following are also general objectives of the group:

• Develop a global vision that allows identifying development trends in Electric Power Systems.
• Expand collaboration with other research groups that work in similar and complementary lines to those developed by the group.
• Integrate as research agents in the new research and development structures, proposed at the regional, national and international levels.
• Extend the collaboration with the Hamburg University of Applied Sciences and the Politecnico de Torino, within the framework of the Master in "Integration of Renewable Energies in the Electrical System", to carry out final master's projects.
• Continue with the work carried out by various members of the group in the international committees of CIGRE and IEEE, and actively promote the participation of other members of the group in other committees of the same organizations, in which the group can contribute its experience. .
• Contribute to the training of members recently incorporated into the group, as well as other interested personnel, through the development of doctoral theses in the research lines of the group.
• Improve and expand the group's technological offer to tackle new development and demonstration projects.
• Continue and improve the transfer of research results through participation in international conferences and publication in prestigious journals.
• Continue and improve technology transfer to companies in the environment through research contracts, specific training courses and specialization courses (Master and Doctorate).
