Abstract:
A novel power system supply architecture that may efficiently use renewable energy sources and work with contemporary DC electrical equipment is the photovoltaic-battery DC.In order to increase PV usage and bus voltage performance, this study proposes a quick and effective maximum power point tracking (MPPT) photovoltaic (PV) control method as well as a battery energy storage system (BESS) bus control approach.First, the mathematical model of each distributed generation in the DC microgridis derived after the photovoltaic-battery and power balance principles are examined. Second, by adding the time-varying smoothing factor and voltage increase, the exponential variable step perturbation and To speed up the MPPT process, an observation method for PV controllers is suggested.The enhanced seeker optimization algorithm (ISOA) optimizes the BESS voltage controller's parameters in light of the significant power fluctuation on the DC bus and the periodic disruption of PV energy absorption. enhanced by the chaotic initialization optimization approach and the variational Cauchy operator.enhanced by the chaotic initialization optimization approach and the variational Cauchy operator.Additionally, a feed-forward compensation approach is created to decrease the hysteresis features and increase the voltage closed-loop reaction speed. Lastly, MATLAB/Simulink is used to implement multi-scheme simulation studies. . The suggested approach increases the MPPT reaction speed from 70 ms to 10 ms and lowers the average voltage ripple percentage from 3% to 1% when compared to the experimental findings of the conventional control method. The outcomes of the experiment confirmed the accuracy and potency of the suggested approach.
