How can peak shaving and valley filling improve energy consumption?

The practices of peak shaving and valley filling not only address the economic aspects of energy consumption but also enhance the reliability and sustainability of energy infrastructures.

What is peak shaving & valley filling?

Manufacturing Plants: With peak shaving and valley filling, manufacturing facilities can optimize their energy use to coincide with the most beneficial times, both operationally and economically. The advancement of technology plays a pivotal role in enhancing the effectiveness of peak shaving and valley filling.

Can a parking lot shave & valley fill the power consumption?

A model is developed to schedule electric vehicle (dis)charging in a parking lot. The aim is to peak shave and valley fill the power consumption of a university building. The study is based on real-world data power consumption and parking lot occupancy. The proposed approach can effectively flatten the power consumption during daytime.

What is a typical electricity peak demand shave system size?

The work in Ref. addresses electricity peak demand shaving in a residential case study, where the results suggest a typical system size ranging from 5 kWh/2.6 kW for low electricity intensity homes to 22 kWh/5.2 kW for electricity intense homes with electric space heating.

What is the difference between peak-shaving and valley-filling?

Specifically, the peak-shaving and valley-filling mechanism reduces the power consumption from 7:00 a.m. until around 1:00 p.m. as in Scenario A, but the key difference in Scenario B is that the corresponding load is steadily shifted from that time onward, namely from 1:00 p.m. until 10:00 p.m. (Fig. 11).

Are peak-shaving and valley-filling effects more perceptible in Scenario B?

In general, the peak-shaving and valley-filling effects in scenario B are more perceptible compared to scenario A.
