摘要:

本文提出了一种新的无模型控制(MFC)机制,使当地的分布水平的电路消耗的光伏(PV)发电的本地建筑负荷,特别是分布式供暖,通风和空调(HVAC)的单位。光伏发电的本地消费将有助于最大限度地减少光伏发电对配电网的影响,减少光伏渗透所需的电池存储容量,并提高太阳能光伏发电的渗透水平。所提出的MFC方法及其相应的智能控制器不需要任何精确的建筑物模型,其中可靠的建模是一项艰巨的任务。即使假设一个好的模型的可用性,各种建筑体系结构将妥协的性能目标的任何基于模型的控制策略。我们的目标是在当地消耗大部分光伏发电,同时保持居住者的舒适度和HVAC装置的物理限制。也就是说,通过在时间和空间上适当调度响应负载以最小化需求和PV生产之间的差异,可以减少电压变化和双向功率流。计算机模拟显示了有希望的结果,其中很大一部分光伏发电可以通过智能控制的帮助下,由建筑HVAC单元消耗。

英文摘要:

This paper presents a new model-free control (MFC) mechanism that enables the local distribution level circuit consumption of the photovoltaic (PV) generation by local building loads, in particular, distributed heating, ventilation and air conditioning (HVAC) units. The local consumption of PV generation will help minimize the impact of PV generation on the distribution grid, reduce the required battery storage capacity for PV penetration, and increase solar PV generation penetration levels. The proposed MFC approach with its corresponding intelligent controllers does not require any precise model for buildings, where a reliable modeling is a demanding task. Even when assuming the availability of a good model, the various building architectures would compromise the performance objectives of any model-based control strategy. The objective is to consume most of the PV generation locally while maintaining occupants comfort and physical constraints of HVAC units. That is, by enabling proper scheduling of responsive loads temporally and spatially to minimize the difference between demand and PV production, it would be possible to reduce voltage variations and two-way power flow. Computer simulations show promising results where a significant proportion of the PV generation can be consumed by building HVAC units with the help of intelligent control.
