Abstract
Conference Title: 2016 IEEE Smart Energy Grid Engineering (SEGE) Conference Start Date: 2016, Aug. 21 Conference End Date: 2016, Aug. 24 Conference Location: Oshawa, ON, Canada Worldwide, many countries spend billions of dollars on the development of renewable energy sources, especially wind generation, to counter the effects of global warming and in response to other environmental concerns. Given the increasing number of remotely located large power offshore wind farms, power sharing control and voltage regulation are significant challenges in the development of large multi-terminal voltage source converter high-voltage direct current (MT VSC-HVDC) transmission grids. Additionally, a wind-power curtailment algorithm is needed in cases of high windpower generation during low power demand from onshore AC networks. This work presents a power sharing control and wind power curtailment algorithm. This algorithm is based on selecting the optimal droop parameters of the power receiving converters and the reference power output for the offshore wind farms to share the offshore wind energy to the MT HVDC network among different AC grids based on desired shares. These desired power shares are defined to fulfill the active power requirements of the connected systems to achieve their objectives.
