1. A method for off-grid load stabilization of a power system comprising: at least one generator, at least one energy store, and a system bus, the method comprising:
receiving generator data from the at least one generator and energy storage data from the at least one energy store;
determining, based on the generator data and/or the energy storage data, a moving average of a system load on the at least one generator;
determining, based on the generator data and/or the energy storage data, an instantaneous load value on the at least one generator;
determining a first electronic storage dispatch (ESD) based on the moving average of the system load and the instantaneous load value on the at least one generator;
providing the first ESD to the at least one energy store; and
causing the at least one energy store to inject power to the system bus or absorb power from the system bus to maintain a frequency of the system bus in response to the at least one energy store receiving the first ESD.
