6 FAQs about [Analysis of energy storage peak load period]
What is a peak load in a decentralized energy plant?
Peak loads are generated due to high-energy demands within short time slots. Such loads could be partially or totally covered by decentralized energy plants if the additional energy that is produced by the power plant while the power demand is low would be stored, for example at night, and used during the high power demand periods.
When does the load profile show peak and low power consumption?
Thus, the examined load profile shows peak power consumption during the morning hours (10:00–13:00 h) and in the evening (18:00–20:00 h) and very low power consumption during the night hours (00:00–05:00 h).
