Reactive Power Planning for Regional Power Grids Based on Active and Reactive Power Adjustments of DGs [PDF]
Energies, 2018 To deal with extreme overvoltage scenarios with small probabilities in regional power grids, the traditional reactive power planning model requires a huge VAR compensator investment. Obviously, such a decision that makes a large investment to cope with a

Fast transient control for power adjustment in a dual‐active‐bridge converter
Electronics Letters, 2017 A transient control for a dual‐active‐bridge (DAB) dc/dc converter to realise power adjustment in a fast and smooth way is proposed. The converter is able to transfer power between two dc sources with two phase‐shifts as control variables.

Design and realization of an adjustable fluid powered piston for an active air spring [PDF]
, 2016 In this paper, we present a new compact hydraulic linear actuator. The concept is developed to change the rolling piston diameter of an active air spring during usage. By doing so, the air spring can actively apply pressure and tension forces. The actuator is designed for small movements at high forces.
