Power Control Of A Microgrid
First Claim
1. A method for controlling power in a microgrid, wherein the microgrid comprises power sources, loads and includes at least one connection to a main grid where a transformer is arranged to transfer electric power between the microgrid, and the main grid, said method includes:
- monitoring the power balance within the microgrid,monitoring the transformer, including monitoring the transformer temperature,detecting a need for overloading the transformer based on the power balance within the microgrid,Whereindetermining a load profile for the transformer based on the power balance within the microgrid,determining a prognosis of the transformer temperature based on the load profile,determining a schedule for power control of the microgrid, wherein the determining of a schedule for power control includes analyzing the prognosis of the transformer temperature.

Abstract
A method for controlling power in a microgrid that includes power sources, loads and at least one connection to a main grid where a transformer is arranged to transfer electric power between the microgrid and the main grid is disclosed. The method includes: monitoring the power balance within the microgrid; monitoring the transformer, including monitoring the transformer temperature; and detecting a need for overloading the transformer based on the power balance within the microgrid. Especially, the method includes: determining a load profile for the transformer based on the power balance within the microgrid; determining a prognosis of the transformer temperature based on the load profile; and determining a schedule for power control of the microgrid, which determining of a schedule for power control includes analyzing the prognosis of the transformer temperature.
