Abstract: Embodiments are generally based on employing a power transmission line in a HVDC link to provide auxiliary power to one of the ends of the HVDC link for facilitating a black start thereof when the HVDC link is de-energized, i.e. when at least one of the HVDC converter stations is de-energized and there is no transmission of power between inverter and rectifier HVDC converter stations on each side of the HVDC link. A relatively small amount of power can be conveyed towards one of the HVDC converter stations via the power transmission line so as to provide power to any auxiliary system(s) of the converter station, for example prior to a black start of the converter station being carried out.

Abstract: A solar power plant including a power conversion system and a method of controlling the power conversion system. Implemented in a DC/AC inverter, the plant includes photovoltaic modules (PV modules) arranged in arrays connected to a respective DC/DC converters. A power collecting grid interfaces between the DC/DC converters and the DC/AC inverter. The method includes monitoring the performance of each PV array by adjusting the voltage level of each interface between a PV array and the corresponding DC/DC converter, and includes monitoring the output power of each DC/DC converter as a feedback for the regulating.
