Offshore wind farm cable connection configuration optimization using Dynamic Minimum Spanning Tree algorithm

A new approach, Dynamic Minimal Spanning Tree (DMST) algorithm, which is based on the MST algorithm is proposed in this paper to optimize the cable connection layout for large scale offshore wind farm collection system. The current carrying capacity of the cable is considered as the main constraint. The dynamic changing of the cable capacity, therefore, the cost during the searching process is presented in this work. Two wind farms are chosen as the studied case and the final results show that the proposed method can save the investment on cables 1.07% and 6.10% respectively compared with MST method. It is a more economical way for cable connection configuration design of offshore wind farm collection system.
