Optimization of inverter and capacitor bank sizing for reactive power management

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to configure an electrical generation facility to meet a power factor requirement at a point of interconnection by:

• determining a range of inverter counts from a minimum quantity to a maximum design capacity for the electrical generation facility;
• generating a plurality of combinations of inverter counts and inverter power factor settings, wherein the inverter power factor settings range from a highest permissible power factor to a minimum permissible power factor based on manufacturer specifications;
• filtering, from the plurality of combinations, combinations where a product of the inverter count and an active power output at the corresponding inverter power factor setting exceeds a peak output limit at the point of interconnection of the electrical generation facility to generate a modified plurality of combinations;
• for each combination of inverter count and power factor setting of the modified plurality of combinations:
• calculating a total reactive power contribution from the inverters;
• determining a plant-level power factor based on the total reactive power contribution from the inverters by determining real and reactive losses across components of the electrical generation facility;
• and
• determining a capacitor bank size to address a remaining gap in reactive power needed to meet the power factor requirement at the point of interconnection;
• generating a configuration matrix comprising a plurality of configurations for the electrical generation facility, wherein each configuration includes a combination of inverter count and power factor setting from the modified plurality of combinations and a corresponding capacitor bank size;
• applying an optimization algorithm to the configuration matrix to determine deployment factors for each configuration of the plurality of configurations;
• and
• selecting a configuration from the configuration matrix based on the deployment factors for each configuration of the plurality of configurations.
