贵州省水风光一体化基地开发研究

Research on the Development of Guizhou Province Hydro-wind-solar Integrated Base

水能、风能、太阳能等可再生能源具有取之不尽、用之不竭、清洁无污染的特点,利用水能、风能、太阳能已成为全球实施经济社会和能源可持续发展的重要选择,但单一的风、光出力过程间歇性强、波动性大、可控性差,利用水电站的快速响应及调节能力可有效平滑新能源出力,提高电能品质,促进新能源消纳。本文从贵州省资源条件和开发现状出发,结合贵州省水电、风电、光伏出力特性和资源分布,提出了贵州省开展水风光一体化基地规划的优势。最后考虑风光出力与负荷的匹配性,提出了贵州省风光开发风电比例在0.4~0.6时对系统影响最小,考虑综合弃风光率5%,贵州省开展水风光一体化基地合理规模约8000MW。

Renewable energy sources such as water,wind and solar energy have the characteristics of being inexhaustible,clean and pollution-free.The use of water,wind and solar energy has become an important choice for the global implementation of economic,social and energy sustainability.However,the single wind and light output has strong intermittency,large volatility,and poor controllability.The regulation performance and compensation capacity of hydropower stations can effectively smooth the output of new energy,improve the quality of electrical energy,and promote the consumption of new energy.Starting from the conditions and development status of water,wind and solar resources in Guizhou Province,combined with the characteristics and resource distribution of hydropower,wind power and photovoltaic power generation in Guizhou Province,this article proposes the advantages of developing a hydro-wind-solar integration base in Guizhou Province.Finally,considering the matching between wind and solar power generation and load,it is proposed that when the proportion of wind power generation in Guizhou Province is 0.4-0.6,the impact on the system is minimal.Considering a comprehensive abandonment rate of 5%,the reasonable scale of developing a water-wind-solar integration base in Guizhou Province is about 8000MW.
