Abstract

Offshore wind power, as a clean and renewable energy source, has become an important way to realize the low-carbon transformation of offshore oilfield platforms. However, different wind power submarine cable connections have a great impact on the cost of submarine cables and the low-carbon transformation of oilfield platforms. Therefore, factors such as wind power resources and low-carbon cost are comprehensively considered, and an optimization method for wind power submarine cable routing for low-carbon energy consumption of offshore oilfield platforms is proposed. With the objective function of minimizing submarine cable construction costs, submarine cable operation losses, and carbon emissions costs of oilfield platforms, a 0-1 combination integer programming model for submarine cable routing optimization layout is established. The second-order cone relaxation is applied to the quadratic power flow equation constraints, achieving an accurate solution of the optimization model. By taking an actual offshore wind farm as an example, the simulation and comparative analysis are carried out. The results show that the method proposed in this paper can significantly improve the economy of the power collection system, select a more low-carbon scheme, and show strong practicability and feasibility.
