A maximum power point tracking (MPPT) converter of a new and renewable energy storage system for tracking and extracting a maximum power from a new and renewable energy to provide the maximum power to a DC link. The MPPT converter includes an MPPT controller changing a controlled variable for maximum power point extraction in proportion to a current slope of the new and renewable energy, and an MPPT extractor extracting a maximum power from the new and renewable energy and converting the extracted maximum power in response to a control of the MPPT controller. The controlled variable variation is set to a large value if the current slope is out of a predetermined current slope range, and the controlled variable variation is set to a small value if the current slope is within the predetermined current slope range.
