Optimization of Wind‐PV Co‐Generation Systems Using Artificial Bee Colony and Back‐to‐Back Voltage Source Converter

IET Smart Energy Systems, EarlyView.
The Graphical Abstract depicts the proposed Artificial Bee Colony algorithm‐based optimal tuning of PI controllers for back‐to‐back Voltage Source Converters in a hybrid wind–PV system. ABSTRACT This paper proposes a hybrid model‐based back‐to‐back voltage‐source converter (B2B‐VSC) system comprising a Photovoltaic (PV) array and a Permanent Magnet ...

Degradation of railway track on heavy haul lines [PDF]

, 2008
The geometric alignment of railway track deteriorates with time, primarily due to the static and dynamic forces exerted by the trains’ wheels on the track. Deterioration of the track’s geometry is called track roughness. The paper reports on the outcomes
