A load controller and method are provided for maximizing effective capacity of
a non-controllable, renewable power supply coupled to a variable electrical load
also coupled to a conventional power grid. Effective capacity is enhanced by monitoring
power output of the renewable supply and loading, and comparing the loading against
the power output and a load adjustment threshold determined from an expected peak
loading. A value for a load adjustment parameter is calculated by subtracting the
renewable supply output and the load adjustment parameter from the current load.
This value is then employed to control the variable load in an amount proportional
to the value of the load control parameter when the parameter is within a predefined
range. By so controlling the load, the effective capacity of the non-controllable,
renewable power supply is increased without any attempt at operational feedback
control of the renewable supply.
