Load distribution for dissimilar generator sets

A method of operating a plurality of gensets comprising:

• connecting a first genset having a first power capacity limit and a second genset having a second power capacity limit to an electrical load, the first genset associated with a first response capability to changes in the electrical load that is faster than a second response capability associated with the second genset;
• applying a first operational range to a first genset and setting a first power target within the first operational range;
• applying a second operational range to the second genset and setting a second power target within the second operational range;
• raising the first operational range within the first power capacity limit and the second operational range within the second power capacity limit in response to a power request increase from the electrical load;
• setting the first power target according to the first response capability and setting the second power target according to the second response capability;
• and operating the first genset intermittently in an interim condition generating power in excess of the first power target to accommodate the second response capability until the second power target is set in accordance with the second response capability.

An electrical power system comprising:

• a first genset having a first power capacity limit and ability to operate within the first power capacity limit;
• a second genset having a second power capacity limit and ability to operate within the second power capacity limit;
• a common bus in electrical connection with the first genset and the second genset in a parallel arrangement, the common bus coupled with an electrical load;
• an electronic controller communicating with the first genset and the second genset to allocate a power request from the electrical load as a first power target within a first operational range applied to the first genset and as a second power target within a second operational range applied to the second genset, the electronic controller configured to raise the first operational range at a first response capability and the second operational range at a second response capability in an event of an increase to the power request from the electrical load, the electronic controller further configured to set the first power target within the first power capacity limit while attempting to raise a second power target within the second operational range as raised, the electronic controller further configured to operate the first genset intermittently in an interim condition generating power in excess of the first power target to accommodate the second response capability until the second power target is set in accordance with the second response capability.
