Abstract

Offshore windfarms are increasingly preferred over onshore windfarms owing to their high-capacity factor. Generally, the offshore windfarms have been located in remote areas from the load center; thus, the surplus power should be transferred effectively to the load center. This work proposes the hybrid AC/DC transmission planning framework to improve offshore the hosting capacity of windfarms and transfer surplus power to metropolitan areas considering the voltage and transient stability. Firstly, the optimal location of the flexible AC transmission system (FACTS) in the AC system is determined to improve the interface flow limit and margin. Then, the strategy for a suitable operation point of high voltage DC (HVDC) is also proposed, considering transient stability to improve the receptivity and transmission capacity of offshore wind energy in DC and AC systems.
