Peak-shaving on the supply side is the storage of PV or wind energy during times when this energy is generated and cannot be consumed or supplied back to the electricity grid.
All storage systems developed by ATEPS have this option. By placing kW/kWh meters in the right locations, it is measured how much energy is generated and how much of it cannot be supplied back. If the battery is not fully charged, you can choose to charge it first and then return power to the electricity grid. If the grid operator would not allow feedback, PV converters can be disabled to meet the grid management requirements.
These activities do not require the intervention of an external aggregator, the algorithms required for this are part of the control of the energy storage system.
