Shipboard Microgrid Frequency Control Using Error Performance Criteria

The rapid advancement of renewable energy technologies and strict regulations imposed by the marine pollution protocol have significantly increased interest in integrating renewable energy sources into marine vessel power systems. But this gives rise to deviating frequency due to irregularities in generation from renewable energy sources. This study primarily focuses on the frequency regulation of shipboard microgrids implementing PID controller. The study employs error performance criteria, namely integral square error (ISE) and integral square time error (ISTE), for fine-tuning the PID controller parameters. The frequency analysis of shipboard microgrids with controllers based on ISE and ISTE methods, are presented and discussed in the research. To improve comprehension of the results, a comparative study is carried out, presenting time domain specifications for shipboard microgrids with and without controllers.
