Power systems, especially those which are small and isolated, are working more and more to the limits of their capacity. Thus there is a need for new structures that give them more flexibility. To this end, the Spanish Transmission System Operator (TSO), Red Electrica de España (REE), in collaboration with various research centres, is working on so...
In this presentation, we show our approach to build data management solutions for a network of sensors. These solutions are based on an architecture that we have called Scala.
The use of MDE to deal with simulations of complex systems enhances the productivity and helps to define an ontology around the domain under study. Our research group has been working with MDE for 20 years and 7 years on its application to complex system simulations. In this tutorial, we will present the new version of Tafat: a framework for buildi...
Simulation of complex and heterogeneous systems is done by decomposing the system into many subsystems. These subsystems are individually simulated and results are integrated by a co-simulation algorithm. In this approach, an interoperability framework that allows the integration of components is required.The FMI standard is becoming the interopera...
A secure and high-quality operation of power grids requires frequency to be managed to keep it stable around a reference value. The deviation of the frequency from this reference value is caused by the imbalance between the active power produced and consumed. In the Smart Grid paradigm, the balance can be achieved by adjusting the demand to the pro...
In recent years, power grids have been evolving to decentralised production and control. Direct Load Control (DLC) methods are oriented to manage loads on the demand side. A DLC method based on Multi-Objective Particle Swarm Optimisation (MOPSO) algorithm is described. This method sets up the operation of the appliances when a power restriction mus...
In solutions based on simultaneous auctions, participants are enabled to conduct and clear their own auctions, so that many auctions can be running at the same time. This configuration is increasingly being proposed for the installation of distributed management systems based on economic criteria in contexts such as the Smart Grid, computational gr...
Critical regimes are present in all socio-technical systems. Usually, man-made systems are designed to avoid these regimes completely, and stay in a stable steady state to avoid uncertainty. However, complexity theory postulates that the edge of chaos, between order and disorder, provides highly interesting phenomena, such as emergence, which are i...
The need to reduce the dependence on fossil fuels has promoted the introduction of new paradigms to improve overall power grid efficiency. Because of this, electrical vehicles are becoming more popular. Notwithstanding, their introduction means new challenges which must be addressed in order that future power grids can support their recharge. To th...

The evaluation of the emergent behaviour in complex systems requires an analytical framework which allows the observation of different phenomena that take place at different levels. In order to observe the dynamics of complex systems, it is necessary to perform simulations so that both local and the emergent behaviour can be observed. To this end,...
Decision making processes in some contexts, such as construction of infrastructures, require the design of prospective experiments. These experiments are designed to test hypothesis raised in the design phase. Following an adaptive methodology, these experiments will feed new iterations. In many cases, the development of these experiments is so cos...

Many experimental studies require the use of in silico simulators where hypotheses are evaluated. Developing these studies in real life may be costly or sometimes even impossible. However, simulated experimental studies require a significant effort to develop software simulators. In some cases, a great deal of time and effort is spent in developing...
Energy systems worldwide, and specially power infrastructures, are facing major changes this century. There are a number of challenges related to the introduction of renewable energy sources, new usages and behaviors as well as the introduction of IT systems, which are emerging into a paradigm change in energy infrastructures. This article presents...
