摘要
电力系统模型对仿真结果的影响很大,建立能够准确描述风电机组/风电场动态行为的数学模型是确保含风电的电力系统仿真结果真实、可信的必要条件。本文综述了风电机组通用模型、风电场等值模型准确度评价的研究进展,重点从评价指标的构建、误差阈值的量化、模型误差的修正3个方面,分析了目前风电场模型准确度评价研究存在的不足和需要进一步研究的方向,同时对能够提升风电场等值模型准确度的误差修正方法进行了趋势分析。
The model of power system has significant influence on simulation result.Establishing a mathe⁃matical model describing accurately the dynamic behavior of wind turbines/wind farms is a necessary condi⁃tion for ensuring the true and credible simulation results of power systems with wind power.In this paper,the study progress of general model of wind generation set and equivalent model of wind farm is described,the present shortcomings of current wind farm model accuracy evaluation research and the direction for fur⁃ther research are analyzed from such 3 aspects as construction of evaluation index,quantification of error thresholds and correction of model errors and,at the same time,a trend analysis of the error correction method that can improve the accuracy of the wind farm equivalent model is investigated.
