摘要:
风力发电具有成本相对较低、技术成熟和适宜规模化开发等优势,因此我国大规模发展风力发电,但大规模风电接入对电网损耗的影响也日渐显现出来。本文首先分析基于大规模风电接入的电网损耗波动特性,其次基于大规模风电接入电网的简化模型,分析造成网损波动的影响机理及影响因子,并由此提出基于损耗影响因子的降损措施。最后,以甘肃河西电网为例,对大规模风电接入电网的影响因子及降损措施进行仿真验证,结果表明了本文所提出的大规模风电接入电网损耗影响因子和降损措施的正确性。
Abstract:
Wind power has advantages of relatively low cost, mature technology and suitable for large-scale development, so large-scale wind power generation is developed in China, but the impact of large-scale wind power integration on power loss is also gradually emerged. This paper first analyzes the fluctuation characteristics of grid loss based on large-scale wind power integration. Secondly, based on the simplified model of large-scale wind power access grid, the influence mechanism and effect factors of network loss fluctuation are analyzed, and then the reduction mea- sures based on effect factors are proposed. Finally, taking Gansu Hexi Power Grid as an example, the effect factors and reduction measures of large-scale wind power access grid are simulated and verified, which show the correctness of the proposed loss effect factors and loss reduction mea- sures of large-scale wind power access grid.
