中文摘要: 目前大规模间歇性电源并网不仅消纳困难,而且对传统确定性电网调控带来严峻挑战,其实质是间歇性规律未有效把握,致使功率变化与能量平衡来不及协调互补,使穿透率持续攀升情况下的常规调控愈发困难。针对上述问题,本项目拟从发掘间歇性电源自身可控性规律的角度着手,分层分区剖析其波动的内在规律,降低预测水平对调度决策的影响,推动其分步渐进参与当前调控系统,实现适合多时间层次的主动性调控。为此,本项目以奇异功率曲线界定与辨识为基础,构建间歇性电源的功率有效域分解模型;以适应当前电网调控为前提,研究适合调度需求的功率有效域奇异性校正方法;进而提出多时间层次间歇性功率流的主动性渐进调控理论。本项目从挖掘间歇性电源自身可控性的角度提出研究思路,对提升电网对间歇性电源的接纳及调控能力具有极大帮助,为促进间歇性电源调控问题的解决提供一种全新的思路,对大规模间歇性电源并网后的电网调控具有重要的理论意义与应用价值。

英文摘要: Currently the variable output of large-scale intermittent power generation presents many integration problems, especially at accommodation and the challenges to traditional control and dispatching mode. The essence is that the inherent regularity of intermittent power generation has not been explored effectively, then the intermittency can not be complementary with power balance, and the conventional control and dispatching modes are becoming increasingly hard under the situation of rising penetration. According to this, the research is carried out about intermittent power generation with novel perspective on its self controllability mining, aiming to analyse its inherent regularity hierarchically, and decrease the influence on dispatching decision from prediction error, then accelerate its incorporation into current control and dispatching mode, at last achieve multi-time level active control and dispatching. For this purpose, based on singularity definition and identification, singularity decomposition model for feature analysis can be built; making adapting to current control and dispatching mode being a precondition, singularity correction modeling considering dispatching demand will be set up; finally multi-time level active and progressive mode based control and dispatching theory is proposed.
