文摘
- •
A novel MPPT strategy based optimal voltage control for PV system is proposed.
- •
The direct relationship between solar irradiance (S), cells’ temperature (T) and operating voltage at MPP (Vpmax) has been found out.
- •
The characteristics of Pmax (output power at MPP)–S–T and Vpmax–S–T are thoroughly analyzed.
- •
The proposed method has astounding accuracy under variable environmental conditions.
