摘要:

为提高高比例新能源电力系统的经济性与可靠性,提出一种考虑风光不确定性下基于主从博弈的机组联合优化调度策略。首先,通过构建Transformer-长短期记忆(LSTM)混合模型对风光出力进行预测,并采用Wasserstein距离建立动态置信区间以刻画风光出力的不确定性;其次,建立风光发电商与火电机组之间的双层博弈模型,引入风险溢价与弃风弃光惩罚机制协同优化出力计划与备用容量。最后,进行算例分析。结果表明,所提策略能有效降低弃风弃光率,提升系统运行经济性,为高比例新能源电力系统的不确定性优化调度提供了解决方案。

Abstract:

In order to improve the economy and reliability of a high proportion of new energy power system, a joint optimal dispatch strategy for units based on master-slave game considering the uncertainty of wind and solar power is proposed. Firstly, the transformer long short-term memory(LSTM)hybrid model is constructed to predict the wind and solar power output, and the Wasserstein distance is used to establish the dynamic confidence interval to describe the uncertainty of wind and solar power output. Secondly, a two-level game model between wind and solar power generators and thermal power units is established, and the risk premium and the penalty mechanism of wind and solar abandonment are introduced to optimize the output plan and reserve capacity. Finally, a case study is conducted. The results show that the proposed strategy can effectively reduce the wind and solar curtailment rate and improve the operation economy of the system, which provides a solution for the uncertain optimal dispatch of high proportion of new energy power systems.

Key words: uncertainty, master-slave game, Transformer-LSTM hybrid prediction, dynamic confidence interval, power dispatch
