Design of off-grid fuel cell by implementing alo optimized PID-based MPPT controller

Abstract

The main objective of proposed paper is to implement an off-grid fuel cell array in combination with DC-to-DC boost chopper and MPPT. To extract the maximum power from the fuel cell array under different conditions, tuned PID-based MPPT technique is adopted. The design parameters of PID controller have critical role to improve the performance of the system. Ant lion optimizer (ALO) algorithm is taken up to get the optimum values of PID parameters to supply suitable duty ratio for DC-to-DC boost chopper to optimize the output power and voltage of the proposed system. P&O-based MPPT technique is carried out to validate the supremacy of PID-based MPPT to upgrade the response of the system. In this paper, the proposed ALO optimized PID controller-based MPPT technique is performed better over conventional P&O technique in terms of the output voltage, current, and power of the fuel cell array.
