Modelling of a Hydro Power Station in an Island Operation [PDF]
There is a strong focus on new renewable energy sources, such as, solar power, wind energy and biomass, in the con-text of reducing carbon emissions. Because of its maturity, hydropower is often overlooked. However, there is an era of hydro oriented research in improving many aspects of this well established technology.

Hierarchical Predictive Control of Microgrids in Islanded Operation
This paper presents a hierarchical control architecture for the regulation of frequency and nodal voltages of a microgrid in islanded operation. Considering systems with both dispatchable and nondispatchable generation, as well as noncontrollable loads, the suggested approach allows to coordinate the MG devices in order to maintain the network ...

An enhanced role for an energy storage system in a microgrid with converter-interfaced sources
An enhanced role for the energy storage system (ESS), strategically placed at the point of common coupling (PCC) of the microgrid with the utility grid, is proposed. During island operation, the ESS ensures that the frequency and magnitude of the voltage
