Voltage stabilisation of SMES VSI DC-link and compensation of reactive power by SMES using optimised switching strategies
This paper presents a novel and optimised switching strategy and control approach for a three-level two-quadrant chopper in a three-level neutral point clamped (NPC) voltage source inverter (VSI) superconducting magnetic energy storage (SMES). Using the proposed switching strategy, the voltage of the inverter capacitors in SMES can be independently controlled. Also, the minimum power and ...

Solarthermal parabolic trough power plants with integrated storage capacity
Parabolic trough power plants use concentrated direct insulation for steam generation in a Rankine cycle. The fundamentals for direct steam generation in parabolic troughs have been developed in recent years, the feasibility was successfully demonstrated at a solar powered test facility reaching steam temperatures of 400°C at a maximum pressure of 100 bar. Important components for the accelerated ...

Power conditioning of an uncontrolled micro-hydroturbine-driven induction generator for distributed generation using a battery energy storage system
Distributed Generation (DG) and its interconnection to the AC power grid is a relatively new concept. DG employs small generators, which are distributed throughout the power system. The electricity is usually generated by renewable energy sources such as wind, hydro and tidal, which are intermittent in nature. These generators connected to the AC grid may lead to severe power quality problems. ...

Scenarios for the role of hydrogen in a future energy system based on renewable energy
An all-renewable energy system for a group of North European countries is investigated by temporal simulation of the demand-supply matching for various system configurations. The role of hydrogen technologies for energy storage and fuel cell applications is studied and applied to both stationary and transportation sectors. It is shown that there is scope for considerable amounts of energy trade ...

Modelling performance of ultracapacitor arrays in hybrid electric vehicles
This paper describes the development of a computer model to model performance of ultracapacitor arrays in hybrid electric vehicles. A Power-Based Model (PBM) was created and the results were compared with data from the University of Idaho's ultracapacitor hybrid Future Truck. The PBM accurately predicts vehicle fuel economy and allows quick simulation speed. This model includes a derived Internal ...
