合理刻画风电场出力不确定性的封闭集合是实现电网鲁棒控制的基础。基于风电场对稳定性影响的量化规律,文中提出一种改进的数据处理方法,显著降低了稳定控制的风险。针对多风电场多时段不确定性建模,综合考虑出力误差的时空相关性和爬坡误差对备用配置的影响,使用广域椭球和超平面约束构建凸性不确定性集合;此外,提出了高维体积最小化的参数求解方法,通过协调相关约束边界,确保模型满足多个预设置信概率;最后,基于实际风电场数据对所提方法进行了验证,结果表明该方法将不确定性集合体积降低了12%,有效提升了模型精度和适用性。
Reasonably characterizing the closed set of wind farm output uncertainty is the foundation for achieving robust control of power grid. Based on the quantitative laws of impact of the wind farms on stability
this paper proposes an improved data processing method that significantly reduces the risk of stability control. For modeling multi-wind farm and multi-period uncertainties
the spatio-temporal correlation of output errors and the impact of ramping errors on reserve configuration are comprehensively considered. A convex uncertainty set is constructed using wide-area ellipsoidal and hyperplane constraints. Furthermore
a parameter solution method based on high-dimensional volume minimization is proposed
which coordinates relevant constraint boundaries to ensure the model satisfies multiple preset confidence probabilities. Finally
the proposed method is validated using actual wind farm data. The results show that this method reduces the volume of the uncertainty set by 12%
effectively improving model accuracy and applicability.
