Patent ID: 7979167

Claim:
A method for controlling operation of a solar power generation system, the solar power generation system having a plurality of solar cell arrays electrically coupled to an electrical grid at a point of interconnection, the method comprising: obtaining a first output parameter value associated with the solar power generation system; determining an error value indicative of a difference between the first output parameter value and a desired output parameter value; determining a first gain value based on at least one of the first output parameter value and a time-varying operational parameter of the solar power generation system, the first gain value determined independently of the error value; determining a first power value based on the error value and the first gain value; determining a second gain value based on at least one of the first output parameter value, the time-varying operational parameter, and a reference value, the second gain value determined independently of the error value; determining a second power value based on the error value and the second gain value; and generating a desired power command for the solar power generation system based on the first and second power values.
