The energy system is in a global transition towards a sustainable energy system. Resource efficiency and environmental concerns are pushing towards change into use of renewable energy resources and to optimizing the energy usage. As a result of this transition there have been a huge increase in new capacity, in Europe mainly from wind and... Read more
Power flow control techniques have been practiced, from using inductors, capacitors, transformers and load tap changers in the earlier days of electrical engineering to power electronics-based solutions in recent years. Even though the costs and complexities of the available solutions vary widely, the basic underlying theory of power flow control is still the same as... Read more
Increasing penetration of renewable resources in the grid poses several challenges to reliable operation. Utilities have begun deploying energy storage technologies as a means of mitigating some of these challenges. Although the presence of energy storage ameliorates the reliability challenges posed by intermittent sources, a quantitative assessment of the exact amount of storage required to... Read more
