线间潮流控制器应用评估策略研究
Research on the assessment strategy of interline power flow controller
随着社会负荷不断增长、网架结构日益复杂,骨干网络潮流分布不均、电压支撑能力不足等问题已成为制约系统输送能力的重要因素。线间潮流控制器(Interline Power Flow Controller, IPFC)是一种潮流控制能力强大的新型FACTS装置,可应用于多条通道的潮流控制和暂态稳定控制,提升稀缺廊道资源的输电效率。考虑到目前缺乏对IPFC应用效果评估的理论研究和指导规划,本文提出了一种基于模糊层次分析的综合评判方法。首先,从静态、暂态、动态等方面定义了电网柔性评估指标,建立评估层次结构,并给出各指标的权重赋值方法。进一步地,在大系统中选取关键输电断面,通过多组算例获取各指标的标度,评估IPFC在典型应用场景下的控制潜力、安全指标及投资价值。最后结合模糊分析给出IPFC方案的综合分值和整体评价,量化装置对系统的作用,为IPFC的规划应用工程提供一定理论依据和技术支撑。
英文摘要:
The uneven distribution of power flow in critical network and the lack of voltage support have become important factors which restrict the transmission capacity. Interline power flow controller is a more powerful facts device, which can be applied to power flow control and transient stability control in multiple transmission channels. Therefore, it is necessary to calculate the control potential and investment value of IPFC in the existing planning grid. First of all, the flexibility evaluation index of typical power grid is defined, and the hierarchy structure and technical scheme of IPFC evaluation system are determined. Further, a significant transmission cross-section in the large-scale system is selected, the gradation of each index through multiple groups of examples is obtained, and the control potential, safety index and investment value of IPFC in typical application scenarios is evaluated. Finally, an evaluation strategy is established based on AHP, and the overall value of IPFC in the power system is given, which provides a theoretical basis and technical support for the planning application engineering of IPFC.
