Energy systems

Technological and societal developments over recent decades have encouraged the use of an increasing quantity of renewable energy sources (wind, solar) for the production of electric energy. People are starting to generate their own energy, becoming producers themselves. At the same time the predictability of both production and consumption of electric energy will decrease, introducing larger imbalances in the electricity network. The current energy production system copes inadequately  with this unpredictability and will soon reach the limit for safe and reliable operation.
