Module-based electrochemical energy storage can be used to reduce the ramp rate of PV generation with fluctuating insolation. As the capacitance of the module-based capacitive energy storage decreases, large fluctuations on the DC link voltage are expected caused by the variation in the PV power. It is important to design and implement effective control …
