Abstract

The error estimation of wind power forecast is of great importance to the dispatch and control, security and defense, etc. of power systems. In this paper, a system used to estimate the wind power forecast error is designed from the viewpoint of decoupling principle. Firstly, the paper refines the decoupling process of estimating wind power forecast error based on numerical feature extraction. Secondly, the database was divided into historical database and real-time database based on the times of reading and writing and how much of the data we use. Then, Man-Machine Interface, System Query, Data Management and Transfer are developed combined with the database. Finally, the paper develops the system that can estimate the wind power forecast error using Qt Creator based on the smart grid scheduling technology support system “D5000”. The designed system has been applied in a provincial power grid in northwestern China. All the demonstrated results indicate the feasibility and practicality of the designed system.

风电预测误差估计系统建模与设计

风电功率预测的误差估计对电力系统的调度控制、安全防御等具有重要意义。本文从解耦原理出发，设计了一种用于风电预测误差估计的系统。首先，对基于数值特征提取的风电预测误差估计解耦过程进行了改进;其次，根据读写次数和使用的数据量将数据库分为历史数据库和实时数据库。然后结合数据库开发了人机界面、系统查询、数据管理和传输等功能。最后，基于智能电网调度技术支持系统“D5000”，利用Qt Creator开发了风电预测误差估计系统。所设计的系统已在西北某省级电网得到应用。所有的论证结果表明了所设计系统的可行性和实用性。
