Abstract: A method for operating a power generation system that supplies real and reactive power to a grid includes receiving a reactive power demand made on the power generation system at an operating state of the power generation system and a grid state. Further, the method includes decoupling reactive power control and voltage control between a generator and a reactive power compensation device so as to reduce an oscillatory response of a reactive power output from the reactive power compensation device and the generator. Moreover, the method includes operating, via a device controller, the reactive power compensation device in a reactive power control mode to generate at least a portion of the reactive power demand.

Abstract: A wireless power transfer system is disclosed. The wireless power transfer system includes a first converting unit configured to convert a first DC voltage of an input power to an AC voltage. Further, the wireless power transfer system includes a contactless power transfer unit configured to transmit the input power having the AC voltage. Also, the wireless power transfer system includes a second converting unit configured to convert the AC voltage to a second DC voltage and transmit the input power having the second DC voltage to an electric load. Additionally, the wireless power transfer system includes a switching unit configured to decouple the electric load from the contactless power transfer unit if the second DC voltage across the electric load is greater than a first threshold value.

Abstract: A system including a converter is disclosed. The converter includes a first switch having one or more first controllable switches coupled in parallel across at least one diode. A first controlling unit is operatively coupled to the converter. The first controlling unit is configured to determine a temperature of the one or more first controllable switches. The first controlling unit is further configured to compare the determined temperature of the one or more first controllable switches with a transition temperature at which a first power loss of the one or more first controllable switches is equal to a second power loss of the at least one diode and control a switching state of the one or more first controllable switches based on the comparison of the determined temperature with the transition temperature.

Abstract: A power conditioning unit used in an electrical system. The power conditioning unit includes a positive bus and a negative bus that are electrically connected to a direct current load to enable supplying direct current electrical power to the direct current load; and a first phase leg, which includes a first diode electrically connected to the positive bus, a first transistor electrically connected to the negative bus, and a first node between the first diode and the first transistor. The first node is electrically connected to an alternating current power source to enable the first phase leg to receive a first phase of alternating current electrical power from the alternating current power source and the first transistor opens and closes to control flow of the first phase through the first phase leg to facilitate generating the direct current electrical power at a target voltage using the alternating current electrical power.

Abstract: A method for operating a power system connected to a power grid includes providing an active filter in the converter power path. Further, the method includes determining a change in attenuation of harmonics of the power system over a predetermined frequency spectrum that is needed to comply with one or more grid code requirements of the power grid. Thus, the method includes actively controlling, via a controller, the active filter to provide the change to the attenuation of the harmonics of the power system so as to mitigate the harmonics of the power system.

The method includes the steps of determining (310) if a wind speed is less than a cut-in speed, calculating (315) a reactive power demand for an electrical grid (102), calculating (320) a reactive power capability of a line side converter (140), determining (325) if the reactive power demand is greater than the reactive power capability, and calculating (330) a reactive power capability of the line side converter (140) and a rotor side converter (130). The method also includes the steps of determining (335) if the reactive power demand is greater than the reactive power capability of the line side converter (140) and the rotor side converter (130), and reducing solar power generation or reconfiguring the line side converter (140) and/or the rotor side converter (130) to meet reactive power demand.
