Method and systems for managing power systems

A power system comprising:

• a first power asset comprising a first power source and a first power controller, wherein said first power controller is configured to instruct said first power source to produce a first amount of power, wherein said first power controller comprises a first filter configured to receive an error amount at a first frequency range;
• and
• a second power asset comprising a second power source and a second power controller, wherein said second power controller is configured to instruct said second power source to produce a second amount of power, wherein said second power controller comprises a second filter configured to receive the error amount at a second frequency range, wherein the error amount is based on a difference between a power demand amount and a sum of the first amount of power and the second amount of power, and wherein said first power controller is configured to:
• instruct said first power source to produce the first amount of power;
• adjust the first amount of power based on the error amount received by said first filter until the error amount received is substantially zero;
• and
• when the error amount received is substantially zero:
• determine a first desired operating amount of power based on said first power source;
• and
• adjust the first amount of power based on the first desired operating amount of power, wherein said first power controller is configured to adjust the first amount of power based on the first desired operating amount of power to adjust the error amount at the second frequency range.
