The theory behind hydropower is very simple: water obeys gravity and imparts the gained kinetic energy onto a turbine, which subsequently drives a generator.  The devil here is, of course, in all ...
Abstract: With the increase of wind power penetration, the frequency of power system is faced with safety problems. Grid-connected wind turbines participate in frequency regulation through rotor ...
Abstract: This paper represents an advanced crosswind stabilization method. Vehicle safety technology such as rear-view mirrors, airbags, child car seats, and seatbelts has improved significantly, ...
