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

越来越多地使用可再生能源技术和与高峰消费相关的高成本电力，促使需要重新评估如何在建筑物中使用能源。公用事业公司和消费者目前都在考虑在非高峰时段或负荷转移期间吸收和储存能源的技术，以克服可再生能源发电和消费之间的不匹配。随着近年来可再生能源的大量涌入，每一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有效运行。这些技术还通过在传统需求高的时期减少能源需求来帮助削峰。

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.
