建筑负荷用能行为习惯与负荷运行特性分析

Analysis of Building Load Energy Use Behavior Habit and Load Operation Characteristic

在双碳目标政策驱动下,我国正构建以新能源为主体的新型电力系统。未来,建筑将成为集发储用于一身的新型能源综合体,不仅要满足绿色低碳的用能需求,还要满足电力系统灵活电力平衡的需求。为实现电力供需平衡,需要分析建筑负荷用能行为习惯与负荷运行特性,实现建筑负荷的高效控制。从源储网荷(备)网格化能源、分区分类维度,对典型家庭负荷、源储网荷(备)单元系统、典型负荷进行分析,得出家庭光储系统设计需根据家庭负荷及用能行为习惯确定,通过源储网荷(备)日周月季年的用能数据客观评价系统运行情况进而挖掘系统节能改善点,提出典型负荷空调分时启动分区控制、热水器定时控制等设想。

Driven by the dual carbon target policy, our country is constructing new power system with new energy as the main body. In the future, the building will become a new energy complex integrating power generation and storage. The building should not only meet the demand of green and low-carbon energy use, but also meet the demand of flexible power balance in the power system. In order to realize the balance of power supply and demand, it is necessary to analyze the behavior habits of building load and load operation characteristics to realize the efficient control of building load. From the grid energy and zonal classification dimensions of source and storage network load(backup), the typical household load, source and storage network load(backup) unit system and typical load are analyzed. It is concluded that the design of the household optical storage system should be determined according to the household load and energy consumption behavior habits. The operation of the system is objectively evaluated through the energy consumption data of the source and storage network load(backup) day, week, month and year, and the improvement points of system energy conservation are explored. Some ideas are put forward, such as time-sharing start-up zoning control of typical load air conditioning and timing control of water heater.
