摘　　要：为应对风力发电与负荷侧的不确定性,提高电力系统对可再生能源的消纳能力,实现输电网和配电网间的优化调度,该文提出应对高阶不确定性的输配电协同优化调度模型.该文模型考虑风力发电及负荷侧的不确定性,在输配电互联的基础上引入电气热综合能源系统.研究结果表明:该文模型能提高系统的风电并网能力,增强系统适应电负荷波动的性能,降低系统的碳排放,提升系统的经济性.该文研究结果可为电力系统应对高阶不确定性制定输配电调度策略时,提供依据和支撑.In order to cope with the uncertainty of wind power generation and load side,to improve the power system's ability to consume renewable energy,and to realize the optimal scheduling between transmission and distribution networks,a transmission and distribution cooperative optimal scheduling model to cope with higher-order uncertainty was proposed in this paper.The model took into account wind power generation and load-side uncertainties and introduced an electrical-thermal integrated energy system based on transmission and distribution interconnections.The results showed that the model in this paper could improve the system grid-connected capability of wind power,enhance the system performance in adapting to electric load fluctuations,reduce the system's carbon emissions,and improve the system's economy.The results of this paper could provide a basis and support for power systems when developing transmission and distribution scheduling strategies to cope with higher-order uncertainties.
