摘要: 在可再生能源消纳问题凸显背景下,可再生能源电源尤其是风电与自备电厂间的发电权交易是一种降低弃能、促进消纳的积极尝试。但是目前缺乏对发电权交易机制促进可再生能源消纳效果的中长期评价与优化工具。提出了基于随机生产模拟的发电权交易促进风电消纳效果的快速定量评估方法。首先分析了发电权交易的执行方式并总结了影响其提升消纳效果的主要因素,构建了中长期弃风电量概率评估模型;然后探讨发电权交易对风电出力概率特性曲线的整形作用,并深入分析弃风改善效果与交易容量、启动交易风电理论功率、交易时间之间的关系,从而实现了对发电权交易关键参数的优化。最后通过算例仿真验证了所提算法在月、年时间尺度上进行快速优化与效果评估的有效性。

Abstract: With renewable energy consumption becoming a key issue, generation rights transaction between wind power and captive plants plays an important role in improving the power system's accommodation capacity. But there is no theory for evaluating and optimizing such mechanisms in the medium and long term. Based on probabilistic production simulation, this paper proposes a medium and long-term evaluation model to calculate system's accommodation capacity rapidly. The main factors affecting accommodation effect are summarized after analysis of operation mode of generation rights transaction. Considering the probabilistic characteristics of load and various power sources, an assessment model is constructed. Then, the shaping effect of the power generation rights transaction on the wind power probability curve is discussed, followed by analyzing the relationship between wind curtailment reduction and three key parameters:transaction capacity, start-up wind power and daily transaction time. The simulation results validate the effectiveness of the proposed algorithm in quick optimization and efficiency evaluation in monthly and annual scale.
