1. A system for controlling an electrical submersible pump (ESP) of a well, the system comprising:
a processor; and
a non-transitory computer-readable medium storing instructions that when executed by the processor cause the processor to perform operations comprising:
obtaining a well model corresponding to the well;
obtaining a target well rate for the well;
receiving, from one or more data sources associated with one or more components of the well, operational data associated with the ESP operating at the target well rate within the well;
determining a target efficiency of the ESP at the target well rate based on the well model; and
modifying, based on the operational data and the target efficiency an operating characteristic of the ESP;
wherein the modifying comprises one or more of:
controlling a flowing wellhead pressure (FWHP) based on the target efficiency of the ESP; and
adjusting an operating frequency of the ESP based on the target well rate and the target efficiency.
