考虑参数空间差异的多区域空调负荷聚合模型

Aggregation Model of Multi-zone Air Conditioning Load Considering Spatial Differences of Parameters

为准确描述空调负荷的工作特性,需建立精确的模型。在单台空调负荷模型的基础上,利用蒙特卡洛模拟方法,依据各种参数的分布特性,建立了空调负荷聚合模型。根据关键参数的空间差异性,建立了多区域空调负荷聚合模型。仿真结果表明,多区域空调负荷聚合建模方法具有可行性和实用性,为空调负荷参与系统功率平衡控制提供基础。

A precise model is required to appropriately depict the working characteristics of air conditioners. On the basis of the physical model of a single air conditioner,an aggregation model is constructed for a group of air conditioners using the Monte Carlo simulation method to sample from the probability distributions of related parameters. Considering the spatial differences of certain parameters, a multi-zone aggregation model is proposed for various groups of air conditioners. Simulation results verify the effectiveness and usefulness of the aggregation model,which paves the way for air conditioners to participate in power balancing of power system.
