Renewable energy resources are playing an important role in reducing the energy crisis. One of the important resources is being wind energy systems. Most of the times, offshore wind power is transferred to the main land grid through VSC-HVDC transmission system due to its advantages. As converters are required for transmission of offshore power, their control mechanism takes a major control overpower transmission. In this work a power system is proposed, wherein a high penetration no storage wind diesel isolated system (HPNSWD) is interconnected to an existing VSC-HVDC system, in order to enhance the power transfer capability of a 200KV, 500MW VSC-HVDC system.
