摘　　要：随着新能源发电技术的高速发展,电网新能源消纳压力日益凸显。与此同时,随着多能转换技术发展,电网与其他类型能源网络的耦合程度不断提高,如何利用不同能源网络灵活性资源消纳受阻新能源,成为当前亟待研究的问题。为此,提出了计及综合需求响应参与消纳受阻新能源的多时间尺度优化调度策略。首先,充分考虑综合能源系统(integrated energy system, IES)特性建立了冷、热、电负荷的多类型需求响应模型。其次,在日前时间尺度,考虑新能源消纳过程中各方利益均衡,建立了基于主从博弈理论的价格型综合需求响应(integrated demand response, IDR)日前优化调度模型;在日内时间尺度,针对新能源日前预测偏差对系统优化影响,建立了考虑激励型IDR日内滚动优化调度模型。最后,通过算例仿真证明了所提策略可深入挖掘多类型负荷需求响应能力,有效提高新能源消纳量。With the rapid development of new energy generation technology, the pressure of new energy consumption in the power grid is increasingly prominent. At the same time, with the development of multi-energy conversion technology, the degree of coupling between power grids and other types of energy networks is increasing. How to use the flexibility resources of different energy networks to dissipate the blocked new energy has become an urgent issue to be studied. This paper proposes a multi-timescale trading strategy that takes into account the multi-energy demand response to participate in the consumption of blocked new energy sources. First, a multi-type demand response model for cold, heat and electric loads is established with full consideration of the characteristics of integrated energy system(IES). Secondly, a price-based integrated demand response(IDR) day-ahead optimal scheduling model based on master-slave game theory is established in the day-ahead time scale, considering the equilibrium of interests of all parties in the process of new energy consumption. At the intra-day time scale, an incentive-based IDR intra-day rolling optimization scheduling model is developed to address the impact of the deviation from the new energy day-ahead forecast on system optimization. Finally, the effectiveness of the strategy proposed in this paper is verified by case simulation.
