Systems and methods for optimized loading of battery inverters

An energy storage control system comprising:

• a plurality of energy storage units configured to output power to a load, the plurality of energy storage units in an energy storage system (ESS);
• a plurality of inverters coupled to the plurality of energy storage units;
• and
• a controller coupled to the plurality of inverters and configured to:
• determine a required power for the load;
• compare the required power for the load with a rated power for the ESS and determine a number of a plurality of energy storage unit groups needed to provide the required power, each of the energy storage unit groups comprising one or more of the plurality of energy storage units and one or more of the plurality of inverters coupled to the one or more energy storage units of the energy storage unit group;
• establish a schedule for the determined number of the plurality of energy storage unit groups to provide the required power, wherein the schedule includes a plurality of time periods for power delivery by the determined number of the plurality of energy storage unit groups;
• according to the schedule, send a first control signal to engage a first set of energy storage unit groups for a first time period of the plurality of time periods and a second control signal to engage a second set of energy storage unit groups for a second time period of the plurality of time periods;
• and
• send the second control signal to engage the second set of energy storage unit groups for the second time period in response to determining an end of the first time period and a beginning of the second time period.

A non-transitory computer-readable medium comprising computer-executable instructions embodied thereon that, when executed by a processor, cause the processor to perform a process comprising:

• determining a required power for a load, the load coupled to a plurality of inverters, the plurality of inverters coupled to a plurality of energy storage units in an energy storage system (ESS);
• comparing the required power for the load with a rated power for the ESS and determining a number of a plurality of energy storage unit groups needed to provide the required power, each of the energy storage unit groups comprising one or more of the plurality of energy storage units and one or more of the plurality of inverters coupled to the one or more energy storage units of the energy storage unit group;
• establishing a schedule for the determined number of the plurality of energy storage unit groups to provide the required power, wherein the schedule includes a plurality of time periods for power delivery by the determined number of the plurality of energy storage unit groups;
• according to the schedule, sending a first control signal to engage a first set of energy storage unit groups for a first time period of the plurality of time periods and a second control signal to engage a second set of energy storage unit groups for a second time period of the plurality of time periods;
• and
• sending the second control signal to engage the second set of energy storage unit groups for the second time period in response to determining an end of the first time period and a beginning of the second time period.
