Analysis of residential electrical thermal storage (ETS) for electrical-grid load shifting

可再生能源技术的使用越来越多，用电高峰带来的高电费，促使人们有必要重新评估建筑物中的能源利用方式。公用事业公司和消费者目前都在考虑在非高峰时间或负荷转移时提取和储存能量的技术，以克服可再生能源生产和消费之间的不匹配。近年来，随着可再生能源的大量涌入，每种能源都根据季节和环境模式发电，公用事业公司需要存储策略来确保电网的高效运行。这些技术还通过在传统上需求旺盛的时期减少能源需求来帮助调峰。 Dimplex North America与New Brunswick Power(NB Power)一起实施了一项试点计划，涉及在全省住宅中安装和监控300台电蓄热(ETS)加热器。这些加热器取代了传统的电脚板加热器，允许NB Power为转移负载的目的储存热能。加热器在非高峰时间吸收和储存能量，以满足高峰时的需求。Dimplex希望评估ETS部门的性能，并确定对公用事业和消费者的影响。

The increasing use of renewable energy technologies and the high cost of electricity associated with peak consumption, prompts the need for re-evaluating how energy is used in buildings. Utilities and consumers alike are currently considering technologies which draw and store energy during off-peak hours, or load shift, to overcome mismatches between renewable energy generation and consumption. With the influx of renewable energy sources coming online in recent years, each generating energy according to seasonal and environmental patterns, utilities require storage strategies to ensure efficient operation of the electrical grid. These technologies also assist in peak-shaving by reducing energy demand during periods when demand is traditionally high. Dimplex North America, in conjunction with New Brunswick Power (NB Power), have implemented a pilot program which involved the installation and monitoring of 300 Electric Thermal Storage (ETS) heaters in residences throughout the province. These heaters, which replace conventional electric baseboard heaters, allow NB Power to store thermal energy for the purpose of load shifting. The heaters draw and store energy at off-peak times to supply on-peak demand. Dimplex would like to evaluate the performance of the ETS units, and determine the impact on the utility and the consumer.
