青海省光气储一体化项目运行方式分析

Analysis of the Qinghai Province’s Integrated Projects Including Photovoltaic,Natural Gas Power Generation and Energy Storage

气电具有优越的调峰性能,也属于清洁能源,未来其与新能源融合发展将具有广阔前景,随着各类电力融合项目的逐步推进,有必要对气电与储能、新能源联合运行情况进行分析。以青海省海西地区光气储一体化项目为例,通过分析光伏发电出力特性和气电、储能调节特性,对比气电自身的不同调峰方式和气电、储能联合运行的调峰方式,基于全年8760 h生产运行模式,综合模拟分析光气储一体化项目的整体运行情况,结果表明气电和储能联合运行可以更好地为新能源调峰,并提高其整体运行效率。

In addition to being a clean energy source,concentrated solar power(CSP)boasts great peak-shaving performance.Its integration with modern energy will offer numerous advantages in the future.It is vital to examine how CSP,energy storage and new energy work together as various forms of power integration initiatives evolve over time.Taking the project of CSP with thermal energy storage in Haixi,Qinghai Province as an example.This paper analyzes the output characteristics of photovoltaic power generation and the adjustment characteristics of CSP and energy storage,as well as compares the different peak shaving methods of CSP itself and the peak shaving mode of combined operation of CSP and energy storage,based on an annual 8760-hour production and operation mode and a comprehensive simulation analysis of the overall operation of the integration of CPS and energy storage.According to the simulation results,integrating CSP and energy storage can increase peak shaving while also boosting overal l operating efficiency.
