Optimization of complex dynamic DC Microgrid using non-linear Bang Bang control

Abstract

DC microgrids are gaining importance in various power electronics applications because of their efficiency in integrating diverse distributed energy sources. However, designing such complex systems is a great challenge, especially when it comes to high efficiency with minimum power losses and signal distortions that would affect the quality of the output. These systems are inherently dynamic and nonlinear, requiring robust control strategies to accomplish stability and quick dynamics under changing load and operating conditions. Linear and nonlinear control techniques can adopt solutions to the present challenges. For a proposed system, a nonlinear bang- bang control strategy is adopted for DC microgrid performance enhancement. It provides fast operation and enhances the system's overall stability. The performance of the system has been rigorously evaluated and analyzed under different scenarios to validate its effectiveness and reliability. Results are stated in favor of the feasibility and efficiency of the proposed control in the maintenance of the desired output characteristics.
