近年来,海上风电产业得到了快速的发展,海上风电平价上网逐渐成为主流趋势。大型海上风电场建设中,降本增效成为海上风电行业能否持续发展的关键。基于此,提出了一种基于混合整数规划的海上风电场集电系统优化规划方法,以最小化集电系统投资、全生命周期网损成本为目标函数,考虑海缆选型、风机高程、节点进出度等因素建立数学优化模型。为保证所提优化模型的计算效率和收敛性,提出采用简化模型作为热启动的加速求解策略。基于两个实际的海上风电场案例进行了算例分析,将所提方法与行业内现广泛采用的规划软件的规划结果进行对比,结果显示在两个海上风电场中采用所提方法可有效降低集电系统的整体投资成本,体现出良好的优化特性,证实了所提模型与算法在海上风电场集电系统规划领域的应用前景。
In recent years
the offshore wind power industry has experienced rapid development
with levelized grid parity gradually becoming the mainstream trend. In the construction of large-scale offshore wind farms
cost reduction and efficiency improvement have emerged as critical factors for the sustainable development of offshore wind farms. Based on this
this paper proposes an optimal planning method of power collection systems for offshore wind power based on mixed-integer programming. The mathematical optimization model considers submarine cable selection
turbine elevation
node connectivity
and other factors
with objectives of minimizing both power collection system investment and life-cycle network loss costs. To enhance computational efficiency and convergence
an acceleration solving strategy using a simplified model for hot-start initialization is introduced. Based on two actual offshore wind farm cases
a numerical analysis is conducted to compare the planning results of proposed method and widely used planning software in the industry. Results show that using the proposed method in two offshore wind farms can effectively reduce the overall investment cost of the power collection system
demonstrating good optimization characteristics and confirming the application prospects of the proposed model and algorithm in the field of power collection system planning for offshore wind farms.
