摘要/Abstract

摘要： 随着新能源基地并网容量的急剧增加,基于长距离区域互联特高压直流电网输送电力的方式将极大地促进新能源在更大空间区域范围内的消纳。针对中国未来新能源大规模、大范围输送配置趋势,提出送受端新能源区域互联消纳能力分析模型,从满足送受端系统净负荷爬坡需求角度提出了送受端电网系统灵活性综合评价方法。以国内某两条跨区直流为对象,结合直流灵活调整运行方式,针对不同直流调整运行方式,进行了情景方案对比分析,并实证对比分析了直流通道采用跟随送端新能源出力特性送电曲线时具有较优的经济性和社会效益。实证结果表明,所提出的模型与方法可为大规模新能源区域互联电网综合评价与生产模拟提供一种有效的模式。

Abstract: With the rapid increase of installed capacities of the renewable energy, the UHVDC power transmission grid based on long-distance regional interconnection will greatly promote the new energy accommodation in larger regions. In this paper, according to the trend of large-scale and large-scope allocation of renewable energy sources in China, an analytical model is developed of the accommodation capabilities in the sending and receiving ends of inter-regional power grids, and a comprehensive evaluation method is proposed of the flexibility of the power systems in the sending and receiving ends from the perspective to satisfy the net-load climbing demand of power systems. By taking two trans-region HVDC systems in China for case study and combined with HVDC's flexible adjustment operation modes, the scenario analysis is carried out according to different HVDC's adjustment operation modes, and it is demonstrated by real cases that the HVDC transmission channel has better economic and social benefits when following the transmission curves of renewable energy output characteristics in the sending end. It is concluded that the proposed model and method can provide an effective mode for comprehensive evaluation and production simulation of interconnected power grids integrated with large-scale renewable energies.

Key words: new energy accommodation, UHV DC transmission, trans-region power grid, time sequence production simulation, Monte Carlo simulation method
