1. An autonomous downhole power generation system, comprising:

  • a power generation device configured to be disposed in an annular space around a portion of a production tubing, wherein the power generation device is switchable between a power generation mode and a bypass mode;

    a power storage device electrically coupled to the power generation device and configured to store power generated by the power generation device; and

    a control processor communicatively coupled to the power generation device, wherein the control processor switches the power generation device between the power generation mode and the bypass mode based on a preprogrammed operational protocol, wherein the power generation device comprises a power generation path and a bypass path, wherein the power generation path comprises a power generation mechanism that generates power when traversed by a fluid, wherein the control processor is configured to open the power generation path and close the bypass path to generate the power by the power generation mechanism, and wherein the control processor is configured to close the power generation path and open the bypass path to disable generation of the power by the power generation mechanism.
