一种含混合储能的综合能源系统运行控制方法An operation control method of an integrated energy system with hybrid energy storage

技术领域technical field

本申请涉及能源调度技术领域，特别是涉及一种含混合储能的综合能源系统运行控制方法。The present application relates to the technical field of energy dispatching, and in particular, to an operation control method for an integrated energy system including hybrid energy storage.

背景技术Background technique

能源是全球社会运转和发展的重要基础，长期以来，由于人类过度依赖资源有限的化石能源，造成不容忽视的环境污染问题。应对能源枯竭和环境污染问题，清洁能源例如电、天然气以及新能源逐渐从研究走向应用。Energy is an important foundation for the operation and development of the global society. For a long time, human beings have been overly reliant on fossil energy with limited resources, causing environmental pollution problems that cannot be ignored. To cope with the problems of energy depletion and environmental pollution, clean energy such as electricity, natural gas and new energy are gradually moving from research to application.

不同地域新能源分布不均，例如具有足够风能用于发电的地区主要在北方平原、草原等开阔地区；能够进行光伏发电的地区集中在高原；能够进行河道水力发电的地区多在黄河、长江沿岸。同时，不同地域用电量、用电情况、用电峰值不同，例如珠三角地区多工厂，白天高压电用电量较大；各地省会大城市人口较多，多在夜晚出现低压电用电峰值。基于上述现状，能源调度与分配的合理性和即时性尤为重要。The distribution of new energy in different regions is uneven. For example, the areas with sufficient wind energy for power generation are mainly in open areas such as the northern plains and grasslands; the areas capable of photovoltaic power generation are concentrated in the plateau; the areas capable of river hydropower generation are mostly along the Yellow River and the Yangtze River. . At the same time, different regions have different electricity consumption, electricity consumption, and peak electricity consumption. For example, there are many factories in the Pearl River Delta region, and high-voltage electricity consumption is large during the day; provincial capitals and large cities have a large population, and low-voltage electricity consumption occurs at night. peak. Based on the above situation, the rationality and immediacy of energy dispatch and distribution are particularly important.

现有技术下，普遍通过铺设输电网络调整电力的调度与分配，然而电路网络设置周期较长，无法应对突发的用电峰值或其他用电状况。In the prior art, power dispatching and distribution are generally adjusted by laying a power transmission network. However, the circuit network has a long setting period and cannot cope with sudden power consumption peaks or other power consumption conditions.
