Abstract
A power management system comprising a processor is provided. The power management system obtains maximum operating capacities of the power converters over time while in the curtailed mode and uses at least some of the maximum operating capacities for determining and commanding an adjusted operating capacity of at least one of the power converters to maintain a substantially constant level of output power.
Claims19
A method for operating power converters of a power conversion system in a curtailed mode comprising:
- obtaining maximum operating capacities of the power converters over time while in the curtailed mode;
- and
- using at least some of the maximum operating capacities for determining and commanding an adjusted the operating capacity of at least one of the power converters to maintain a substantially constant level of output power.
A power management system comprises a processor for obtaining maximum operating capacities of power converters over time while in a curtailed mode and using at least some of the maximum operating capacities for determining and commanding an adjusted operating capacity of at least one of the power converters to maintain a substantially constant level of output power.
A solar power conversion system comprising:
- a plurality of photovoltaic modules for generating DC power;
- a plurality of power converters for converting the DC power to AC power;
- and
- a power management system for:
- operating the power converters in a curtailed mode;
- obtaining a first set of maximum operating capacities of a first set of power converters while ramping up the operating capacities of the first set of power converters;
- obtaining a second set of maximum operating capacities of a second set of power converters while ramping up the operating capacities of the second set of power converters and simultaneously ramping back the operating capacities of the first set of power converters;
- and
- adjusting an operating capacity of at least one power converter to maintain a substantially constant level of output power during insolation modifications.
