Abstract
The invention relates to a hybrid integrated wind-solar-diesel-city power supply system, which comprises at least one subsystem selected from wind power subsystems or solar power subsystems and at least one diesel-city power subsystem, a direct-current bus unit, a main control unit, multiple high frequency rectifiers and a direct-current distribution unit. Each one subsystem has a DC output coupled to said direct-current bus unit for afflux. Said main control unit is configured to select a set of subsystems from the wind and solar power subsystems and enable the selected set of subsystems but disable others, so as to let a sum of maximum power output of all enabled subsystems to be larger than or equal to power demanded while minimize the number of the enabled subsystems contained in the selected set of the subsystems, and adjust operation of the selected subsystems so as to optimize the system efficiency, and also configured to control current and voltage output of said high frequency rectifier according to the operation status of said direct-current distribution unit and the voltage and current output of said direct-current bus unit, thereby advantageously increasing efficiency a…
