摘要

针对分布式能源系统（DES）的运行,提出一种基于混合时间尺度调控的双层优化运行方法。该方法以最小化系统日运行成本和电相关设备的功率调整量为目标,构建上层分钟级和下层秒级的优化调度模型。上层调度涵盖响应速度不同的冷、热、电设备,并通过不同时间间隔对其进行调控,实现混合时间尺度的调度优化。下层主要调度电相关的快速响应设备,以提高短时间尺度内电力供应的可靠性。结果表明,所提方法能更准确地描述冷热设备的响应特性。与单层调度相比,冬季和夏季典型日的日运行成本分别降低5.2%和24.3%;可再生能源利用率提高6.9%和3.0%;一次能源利用率提升4.0%和26.6%;一次能源节约率达到4.2%和22.3%,系统的经济性和能源利用效率显著提升,可有效保障系统的高效平稳运行。

Abstract

Aiming at the operation of distributed energy system （ DES ）, this paper proposes a bi-level optimization operation method based on mixed time scale regulation. This method aims to minimize the daily operating cost of the system and the power adjustment of the electrical related equipment, and constructs the optimal scheduling model of the upper minute level and the lower second level. The upper-level scheduling covers cooling, heating and power generation equipment with different response speeds, and regulates them through different time intervals to achieve mixed-time scale scheduling optimization. The lower layer mainly schedules power-related fast response equipment to improve the reliability of power supply in a short time scale. The results show that the proposed method can describe the response characteristics of cooling and heating equipment more accurately. Compared with single-layer scheduling, the daily operating costs of typical days in winter and summer are reduced by 5.2% and 24.3%, respectively. The utilization rate of renewable energy increased by 6.9% and 3.0%; the primary energy utilization rate increased by 4.0% and 26.6%; the primary energy saving rate reached 4.2% and 22.3%, which significantly improved the economic performance and energic performance utilization efficiency of the system and effectively guaranteed the efficient and stable operation of the system.
