Subjective–objective methodology on selection of power quality compensation technology in AC–DC network with electrified railways

The Journal of Engineering, 2019
Electrified railways contain DC devices and cause power quality (PQ) issues such as harmonics, unbalance, and low-power factor, which should be solved by the most effective compensation technology to reduce the cost.

Generic maximum power point tracking controller for small-scale wind turbines [PDF]

, 2012
The output power of a wind energy conversion system (WECS) is maximized if the wind rotor is driven at an optimal rotational speed for a particular wind speed. To achieve this, a Maximum Power Point Tracking (MPPT) controller is usually used.
