Why complexity is rising? With the integration of renewable energies, storage units including EVs, active demand and other advanced components (i.e. smart meters, smart transformers etc), into power grids, as well as all the “intelligent” functions needed for their management, the complexity of the electrical system is rising [6]. Smart electrical systems are complex because…

The Dynamics of Future Power Grids: What Should We Expect?
I. THE EU ENERGY POLICY ON RENEWABLE ENERGY SOURCES The climate change and associated consequences have been the driving force behind energy policies in every region in the world over the last decade! The broad target is towards reducing CO2 emissions in the atmosphere to levels detected in the 1990s [EU Energy Policy to 2050].…

Why do we need to make our buildings more “energy-flexible”?
A need for more flexible energy systems As well introduced by Jesus in his article of January, the electrical grids are complex systems that must be balanced at every moment, so that the energy being produced is consumed instantly. This task proved to be relatively easy when power grids were supplied only by conventional plants…

On Low Inertia Grids
Traditional power systems rely on conventional synchronous generators, whose output power is fully controllable, to satisfy the power demand at each time instant. With the increasing share of renewables in the grid, new stability and reliability problems arise in the power grid. The standard question is, what do we do if there is no sun…
