摘要

本文的中心目标是评估热分散对真实校园电网的影响。首先,介绍了电电网和热电网。作为实现热分散的第一步,不同程度的分散来自消费者的热负荷分布。该分析的目的是为校园内现有建筑确定大小的热泵的具体分配。在热网内使用热泵有许多优点,但也可能对供电电网产生负面影响。利用一个真实大学校园的网格模型对这些影响进行了分析。定义并比较了不同分配热泵比例的场景。目的是通过评估电缆和变压器的负荷以及是否符合规定的电压范围,确定由于使用热泵而导致的关键网络运行。

Influence of a Decentralized Heat Supply on the Electrical Grid of a Campus Quarter
The central objective of this paper is to evaluate the effects of thermal decentralization on the electrical grid of a real campus. First, the electrical as well as the thermal grid is introduced. As a first step towards the thermal decentralization, different degrees of decentralization are derived from the thermal load profile of the consumers. The aim of this analysis is the concrete allocation of heat pumps of defined sizes to existing buildings on the campus. The usage of heat pumps within the thermal grid has numerous advantages but can also have a negative impact on the supplying electrical grid. These effects are analyzed using a grid model of a real university campus. Scenarios with different share of distributed heat pumps are defined and compared. The objectives are to identify critical network operation due to the use of heat pumps by evaluating the loading of cables and transformers as well as the compliance with the prescribed voltage range.
