Battery storage system for residential electricity peak demand
To conduct a peak shaving simulation a maximum electricity grid demand limit is first defined for the house (e.g. PG,Limit = 5 kW). If the house demand is above this limit (e.g. PH = 6 kW), the BESS activates and the inverter discharges the batteries to meet any house demand beyond the grid demand limit (e.g. PInv = PH − PG,Limit = 1 kW

Understanding Peak Shaving and Battery Storage
In essence, peak shaving ensures that you only ever pay the lowest possible rate for the energy that you''re pulling from the grid.

Comprehensive configuration strategy of energy storage
The rapid development of photovoltaics (PVs) and load caused a significant increase in peak loads and peak-valley differences in rural distribution networks, which require load peak shifting and line upgrading. Large peak-valley differences also bring challenges on the safe operation of the utility power grid.
Control and Reduction of Peak Power Loads
Peak power loads are high points, sometimes spikes in demand for power. Peak loads are a problem for utilities and their customers alike. For utilities, peak loads must be balanced with supply to avoid power shortages. When the utilities can''t respond quickly enough with their own power, they need to source power on the open
