广东电网风电出力特性分析及其经济性评价

摘要

风电出力特性的研究对于低碳经济发展大背景下含规模风电接入的电力系统规划运行至关重要。基于风电场群的分区分片划分和多风电场运行模拟技术,定量分析了广东规模风电的出力特性和容量效益。研究表明,规模风电接入将增大系统调峰需求,需要在电网规划建设和风电配套政策制订方面引起足够重视。从系统运行成本、煤耗、污染物排放等多个角度进行的经济性评价显示,尽管规模风电接入对常规机组替代作用相对有限,但对于广东节能减排与低碳发展具有重要意义。%To study the characteristics of wind power output is very important for the planning and operation of a power system integrated with a large scale of wind power under the background of low-carbon development.Based on the simulation of the operation of a wind farm group integrated with district wind farms,this paper analyzes quantitatively the characteristics of wind power output and its economic evaluation in Guangdong Power Grid（GPG）.The results show that to integrate a large scale of wind power in a power system increases the requirement of peak load regulation of the system so greatly that it must be considered carefully in the system planning and wind power policy making.The economic evaluation in terms of the system operation cost,coal consumption,pollutant discharge,etc.indicates that a large scale of wind power is of great significance to energy saving,emission reduction and low carbon development for Guangdong province though its effect of replacing the traditional units is relatively limited.
