US 2026/0074518 A1 · METHOD OF CONTROLLING A POWER SYSTEM

Abstract

A Method of controlling a power system, comprising: determining whether a state of charge of an energy storage system lower than a first threshold value. When the state of charge is lower than the first threshold value, a power generator is activated and determining whether the power generator is abnormal. When the power generator is abnormal, supplying the power to loads by the energy storage system. When the power generator is normal, supplying the power to loads by the power generator. Determine whether the state of charge of the energy storage system is lower than the second threshold value, and reduce a part of loads when the state of charge is lower than the second threshold value.

A method of controlling a power system, comprising:

determining whether a state of charge of an energy storage system is lower than a first threshold value;
when the state of charge is lower than the first threshold value, a power generator activating and determining whether the power generator is abnormal;
when the power generator is normal, supplying the power to loads by the power generator;

A power system, comprising:

an energy storage system connecting to a bus, configured to power a plurality of loads, and the energy storage system including a state of charge;
a power generator connecting to the bus configured to power the plurality of loads;
a plurality of switches connecting the plurality of loads to the bus, and
a controller configured to determine whether the state of charge of the energy storage system is lower than a first threshold value, and whether the power generator is abnormal,
wherein when the state of charge is lower than the first threshold value, the controller activates the power generator,
when the power generator is normal, the power generator supplies the power to the plurality of loads,
when the power generator is abnormal, the energy storage system supplies the power to the loads, and the controller determines whether the state of charge of the energy storage system is lower than a second threshold value, and
when the state of charge is lower than the second threshold value, the controller reduces a part of the plurality of loads by the switches.
