防城港负荷需求数据

本数据集是对防城港港口负荷的详细模拟记录，旨在全面反映港口作业的能源需求动态。将防城港港口负荷分解为岸电、岸桥、场桥及冷藏箱四个关键子负荷，并对其进行了连续30天、分辨率为3分钟时间的动态记录，各负荷具体情况如下：
1.岸桥负荷:作为船岸间集装箱装卸作业的核心能耗表征，岸桥瞬时功率水平直接取决于当前投入作业的岸桥数量与岸桥类型，岸桥负荷反映了港口前沿作业的实时强度。
2.岸电负荷:该负荷主要源于船舶靠泊期间，为维持船上辅助设备运行而产生的电力需求。在本模拟中，其负荷的大小与接入岸电的船舶数量和船舶类型相关。其负荷曲线与船舶的到港、离港事件紧密耦合。
3.场桥负荷:该负荷对应于堆场内部的集装箱水平搬运与堆码作业。其负荷与处理入场或出场集装箱的堆场区域活动直接相关。其动态变化不仅与岸桥的卸船速率相关，同时也受到集卡在堆场内的提箱、送箱等陆侧疏运效率的影响。
4.冷藏箱负荷:其由堆场内所有通电制冷的冷藏箱独立运行的功率叠加。该负荷的总量取决于堆场中冷藏箱的实时库存数量，相较于前三类作业型负荷，其变化通常更为平缓但持续性更强。
综上所述，本数据集通过提供高透明度的港口负荷数据，为港口负荷的精准预测、能源系统的优化配置以及智能调度策略研究，提供了坚实可靠的数据基础。

This dataset provides detailed simulated records of the port load of Fangchenggang Port, aiming to comprehensively reflect the dynamics of energy demand during port operations. The port load is decomposed into four key sub-loads: shore power, quay crane, yard crane and reefer container, with continuous 30-day dynamic recordings at a 3-minute temporal resolution. The specific details of each sub-load are as follows:
1. Quay crane load: As the core energy consumption indicator for container loading and unloading operations between ships and the shore, the instantaneous power level of quay cranes directly depends on the number and types of quay cranes currently put into operation. This load reflects the real-time intensity of operations at the port front.
2. Shore power load: This load mainly stems from the electricity demand for maintaining the operation of onboard auxiliary equipment during ship berthing. In this simulation, its magnitude is correlated with the number and types of ships connected to shore power. Its load curve is tightly coupled with ship arrival and departure events.
3. Yard crane load: This load corresponds to the horizontal handling and stacking operations of containers within the yard. It is directly related to the yard activities of processing inbound or outbound containers. Its dynamic changes are not only related to the unloading rate of quay cranes, but also affected by the land-side transportation efficiency such as container trucks picking up and dropping off containers in the yard.
4. Reefer container load: This is the superposition of the independent operating power of all energized refrigerated reefer containers in the yard. Its total amount depends on the real-time inventory quantity of reefer containers in the yard. Compared with the first three operational loads, its changes are usually gentler but more sustained.

In summary, this dataset provides highly transparent port load data, laying a solid and reliable data foundation for accurate prediction of port loads, optimal configuration of energy systems, and research on intelligent scheduling strategies.
