摘　　要：电网容易受到场景约束的影响,新能源风电场无法送出大量风电,为了修正风电消纳数据,设计了基于模糊场景聚类的新能源风电消纳误差修正系统。分析系统运行场景,使用S5PV210微处理器,为系统提供丰富接口。设计误差修正控制器,避免系统修正过程出现误差。在多目标求解原则支持下,搭建模糊场景。根据风电场历史运行数据,计算基准调度方案对新能源风电消纳的结果,获取新能源风电消纳误差序列。确定最佳聚类数,结合历史异常数据修正误差。由实验结果可知,该系统风电功率序列统计结果与理想数据存在最大为1 MW的误差,弃风功率序列统计结果与理想数据一致,所设计系统误差修正结果较好。The power grid is easily affected by scene constraints,and new energy wind farms cannot send a large amount of wind power.In order to correct the wind power consumption data,a new energy wind power consumption error correction system based on Fuzzy scene clustering is designed.By analyzing the system running scenario,the S5PV210 microprocessor is used to provide rich interfaces for the system.The error correction controller is designed to avoid the error in the system correction process.Based on the principle of multi⁃objective solution,a fuzzy scene is built.According to the historical operation data of the wind farm,calculate the results of the new energy wind power consumption of the benchmark dispatching scheme,and obtain the new energy wind power consumption error sequence.The optimal cluster number is determined,and the error is corrected by combining the historical abnormal data.It can be seen from the experimental results that there is a maximum error of 1 MW between the statistical results of the wind power series of the system and the ideal data.The statistical results of the abandoned wind power series are consistent with the ideal data,and the error correction results of the designed system are better.
