丹麦：哥本哈根采取了成为一名公司的雄心勃勃的目标2- 到2025年中立城市，地区供暖起着重要作用。在哥本哈根的诺达夫港（Nordhavn Harbour）的弹性示范厂，该港口为游轮码头提供区域供暖，显示了您可以通过电气化和扇形耦合到多远。它发出的Co少315吨2每年与基于LPG气体的替代品相比。
发现使用VLT®驱动器储能如何确保柔性功耗以减少排放。
基于地下水的区域供暖
哥本哈根Nordhavn区的Hofor（大哥本哈根公用事业）供暖于2018年成立，是EnergyLab Nordhavn的示范项目，该项目还提供了三个Cruise Ship Terminals和附近的联合国儿童基金会仓库。Flexheat植物包括一个基于地下水的热泵，该热泵从150 m深的井中检索到。盐水10.5°C的水通过用氨水作为制冷剂的热交换器泵送。温度通过两个压缩机分为两个步骤，在一个热交换器中，将浓缩氨的热量转移到地区供暖水中，然后将其通向一个储罐，并在三个巡航船舶终端中向消费者抽水。和联合国儿童基金会大楼。弹性热线设施总共具有1兆瓦的加热能力。

4 MWH虚拟电池
在功耗中创造灵活性的一种方法是通过扇形耦合，在其他能源系统中存储过多的电力。在区域供暖供应中，带有热储存的热泵在丰富而廉价时可以使用电源；并避免在系统中的峰值负载时使用它，例如下午晚些时候，大多数人下班回家并打开灯光和家用电器。哥本哈根Nordhavn中的Hofor（大哥本哈根实用程序）flexheat项目是这种类型的扇区耦合的一个很好的例子。热能储能由100立方米储罐组成，对应于4 MWH的“虚拟电池”。
智能操作确保灵活的功耗
Flexheat工厂可以以六种不同的模式运行。这些模式之间的智能切换可确保植物在电价和天气预报方面尽可能有效地运行。例如，当风力涡轮机以全功率收获时，价格很低，弹性设施可以有助于更高的绿色能源开发系数。
面临的挑战是，在市场关闭之前，必须提前一天确定电力的购买。
霍弗（Hofor）能源策划者塔尔·凯杰德（Gad Kjeld）解释说：“该设施的智能操作是基于电价和天气预后的，我们考虑了在类似天气条件下在历史上观察到的电力消耗。除了当前的操作数据外，这些数据还被馈入算法，这有助于我们制定第二天使用电力的计划。机器每次都学会一点，由于我们输入系统的数据，因此变得更加聪明。这种机器学习将使我们在未来根据有利的电价运营设施时变得更好。”
VLT®驱动器有助于快速响应
由VLT®驱动器调节的电动锅炉可以升高温度，因此该工厂可以在电价最高时期的储藏罐中迅速向客户提供热量。“VLT®AquaDrive单元可以在短短几分钟内将热泵从最低加速到最高性能，而电动锅炉可以在短短几秒钟内向上调整，” Hofor的Energy Planner Tore Gad Kjeld解释说。
节省电费和二氧化碳排放
多少合作2Nordhavn的Hofor Flexheat工厂可以节省环境吗？Tore Gad Kjeld估计，今天的节省约为315吨CO2每年，就LPG燃气锅炉而言，这将是区域加热溶液的最佳化石燃料替代品。而且，将来，当电力吸收变为100％绿色时，节省的可能性可能达到430吨CO2每年。
