Residential microgrids are mainly based on renewable energy sources (i.e., mainly on photovoltaic panels), energy storage systems (that enable time-shift between production and consumption), and on power converters representing control points that by proper operation ensure overall system stability and quality of power supply. For optimal techno-economical microgrid operation, i.e. microgrid voltage...
Based on the I–V equation of photovoltaic (PV) cell and the output characteristics of maximum power point tracking (MPPT), this paper proposes a novel identification method to identify four key parameters of PV array: photo current Iph, negative saturation current I0 , diode ideality factor n and the series resistance of cells Rs, by using the measured input and output data of PV array. According...
Photovoltaic array needs an intermediate maximum power point trackers as their V-I characteristics are non-linear. Successful power tracking depends on the converter and its tracking parameters. The purpose of this investigation is to introduce a procedure for selection of the tracking parameters. To demonstrate the proposed approach a fourth order buck converter, belongs to higher order family, is...
