摘要:

随着海上风电的大规模开发,合适的海上风电柔性直流并网位置更有利于其优势的发挥。针对大规模海上风电经柔性直流接入陆地电网的并网选址,通过分析其并网主要影响因素,提出风电消纳能力、电网电压稳定性、并网点脆弱度和建设成本的评估指标。基于信息熵和模糊层次分析法,建立综合赋权模型确定各指标权重,提出并网点综合优化评估方法。某海上风电接入山东电网的仿真结果表明,所提方法增强了风电消纳能力,提高了电网安全稳定性。

Abstract:

With the large-scale development of offshore wind power, the suitable access point to power grid for offshore wind farm is more beneficial for voltage source converter high voltage direct current (VSC-HVDC) power transmission. Aiming at large scale offshore wind farm integrated by the VSC-HVDC, the evaluation indexes of wind power accommodation capability, grid voltage stability, grid-connected point vulnerability and construction cost were proposed by analyzing the main influencing factors of grid-connected. Based on the theory of information entropy and fuzzy analytic hierarchy process, a combination weighting model was established to determine the index weights, , and a comprehensive optimization method of access point selection was proposed. Simulation results of eastern Shandong power grid of China integrated with offshore wind farm demonstrate that the proposed method enhances the capability of wind power accommodation and improves the security and stability of power grid.

Key words: offshore wind power, voltage source converter high voltage direct current (VSC-HVDC), access point selection, fuzzy analytic hierarchy process, security accommodation
