Abstract:
1. A method of tracking a maximum power point of a photovoltaic module, comprising: measuring output voltage (v determining output voltage (e) of an inverter connected to the photovoltaic module; measuring output current (i defining a variable (z) relating to energy of a capacitor using the measured PV module output voltage; extracting a second harmonic component ({tilde over (z)}) from the defined variable (z); estimating a second harmonic component ({tilde over (p)}) of module output power (p) using the defined variable (z), measured output current (i multiplying the extracted ({tilde over (z)}) and the estimated ({tilde over (p)}) second harmonic components; extracting a DC component ( forming a control signal (P;v
