Classification: CPC H  G  Y | IPC H

Claim 14:
15. A power generation system comprising:
an inverter connected to an energy source and configured to supply power to a load network including at least one controllable load, said inverter including a processor configured and adapted to control the at least one controllable load of the load network,
the processor of said inverter including;
a net load detector configured and adapted to detect a net load of the load network;
a power export analyzer configured and adapted to determine an inverter power transfer of the inverter and a grid power transfer of a grid to the load network; and
a power manager configured and adapted to vary a power output of the inverter and a power consumption of the at least one controllable load based on the determined inverter power transfer, the determined grid power transfer, an export condition violation based on an allowable amount of power transfer to the grid, and a derating state of the energy source;
wherein the power manager is configured and adapted to perform the following steps;
decreasing power consumption of the at least one controllable load depending on the grid power transfer, in response to determining the energy source is not in the derating state, under a presence of the grid power transfer and no export condition violation;
checking the derating state of the energy source; and
increasing the power consumption of the at least one controllable load by a predefined value in response to determining the energy source is in the derating state.
