Peak-shifting electricity storage equipment

What is peak load shifting?

Also, variability of power generation based on renewable energy such as solar and wind, has a huge impact on the electricity supply . Peak load shifting is a possible solution, with electricity being stored during low load periods for use in peak load periods .

Should battery energy storage systems load shift electricity to off-peak intervals?

It is not always beneficial to load shift electricity to off-peak intervals simply to benefit from electricity market prices. However, with Battery Energy Storage Systems, load shifting is always beneficial. Battery Energy Storage Systems empower end users with the ability to decouple energy consumption and payment for that consumption.

Does storing heat affect peak load shifting?

Because of the fact that heating, cooling and air conditioning in many developed countries are responsible for almost 30 percent of the total electricity consumption , storing heat (or cold) could contribute significantly to peak load shifting.

What is peak load?

1. Introduction High electricity usage at certain times of the day, known as peak load, introduces stress to the grid as supplied electricity is inadequate during the high peak demand period. In order to satisfy such demand, expensive peak power generation must be brought on line during the peak period .

What is load shifting?

The concept of load shifting is nothing new, in fact, industrial and commercial sites have been using this technique for many years to optimize energy consumption and reduce electricity costs. Load shifting is an electricity load management technique in which load demand is shifted from peak hours to off-peak hours of the day.

Can price-based method be used to perform peak load shifting?

Price-based method were experimentally used to perform peak load shifting. A cost savings up to 16.5% per day were achieved for the freezer experiment. A cost saving up to 62.64% per day were achieved for the building experiment. 1. Introduction
