辽宁电网风电、光伏接纳能力研究
|
摘要
随着可再生能源的不断发展,可再生能源大规模接入将对电网造成严重影响,研究电网对可再生能源的接纳能力具有重要意义。基于辽宁省电网现状网架结构,通过分析风电、光伏等可再生能源电源的出力特性,拟合出典型日出力曲线,提出"基于层次分析模糊"的规划方法。该方法评估了2020年该省各地市非水电可再生能源的接纳能力,并通过软件进行潮流分析与验证。分析结果表明:该方法可以准确得出辽宁电网在规划水平年可接纳的非水电可再生能源的容量,从而有效促进可再生能源的健康发展及消纳,为政府及公司的可再生能源规划工作提供技术支撑。
With the rapid development of renewable energy, renewable energy integrates into power grid can severely influence the power grid.It is significant to study the capacity of renewable energy integration.Based on the electrical structure of Liaoning province electric grid,through analysing the output characteristics of renewable energy such as wind and solar power,the output curve of a typical day can be solved via regression methods.It proposes the "analytic hierarchy fuzzy theory"planning method.The method evaluates the capability in cities of Liaoning province receiving non-water renewable energy in 2020.Then a simulation validation is done with power flow analysis.The analysis shows that the evaluation is accurate.The outcome of this research can facilitate the usage of renewable energy and support the government with strategy in renewable energy planning.
