Abstract

The iterative pace of wind turbines entering the market is quick due to the development of offshore wind power in the deep sea and large-scale directions, but the overall development cycle of offshore wind farms is lengthy and does not keep up with the pace of wind turbine model research and development. Therefore, various wind turbine generator (WTG) models may be combined and deployed during the development of offshore wind farms; however, one of the key challenges in optimizing the topology of mixed-match WTGs is deciding which topology is the best from the perspectives of economy and reliability among various models. Therefore, the circuit division and path design of offshore wind farms are completed by the improved K-means algorithm and the improved Prim algorithm, and the dynamic cross optimization strategy is adopted to complete the handling of the cross of the sea cables in the topology. Finally, the economy and reliability cost of each topology scheme are calculated. The efficacy of this method is demonstrated by the topology optimization outcomes for several mixed-match WTG scenario situations.
