Abstract

Abstract: To meet the requirements of centralized integration of large scale wind power on the economy and security of transmission network expansion planning, a general scheme is proposed for establishing the transmission network expansion planning platform with large scale wind power integration. By applying the transmission network optimization planning theory which considers the risk and economy, an integrated information management and transmission network expansion planning system is developed, which has such functions as power fluctuation analysis of wind farm group and transmission capacity. optimization, collection and management of historical power output data of in-service wind farms, information processing of proposed wind farms, and comprehensive evaluation of the optimal planning. An evolution model is constructed and an practical wind power output forecasting method of wind farm groups is proposed based on the historical wind power output, and a comprehensive transmission network evaluation index system is also established, which can provide an effective technical support for intensive data analysis, high accurate output forecasting, precise scheme assessment and global management of transmission network expansion planning.

Key words: wind farm group, power transmission network, expansion planning, fluctuation characteristics, platform, output forecasting, scheme assessment
