The recent development in the integrated energy generation as well the distributed generation with the offshore wind farms provides good solution and an experienced significant growth to meet the load demand in recent years. Technical knowledge allow the design of wind farms at higher distances, making the high voltage dc (HVDC) transmission a real alternative to current high voltage ac (HVAC) transmission. When the network is decoupled from the wind farm by a dc link, there is no need for a mandatory use of three-phase generator. To the contrary, multi-phase generators can be used and the wind farm can benefit from inherent advantages and recent developments of multi-phase drives. This preliminary study shows some of the potential advantages of the dual three-phase generators in wind energy conversion systems (WECS). The idea of the WECS as well the Solar is inevitable as Limited fossil resources, the continuous increment in fuel prices and severe environmental problems require new sustainable electricity generation options, which utilize renewable energies. Wind energy, solar photovoltaic etc. The objectives of this paper is to develop an assessment methodology for renewable energy Wind /Solar electric generation and energy storage facilities integrated into electric power distribution systems with proposal with HVDC as the transmission system. the advantages of both the generation as well smart efficient transmission . The approach addresses the distributed benefits of electricity generation from renewable sources and their true value to the system, and to apply the methodology to the real time analysis.
