Approaches for short-term photovoltaic energy production forecast in Russian climate conditions

Different techniques for short-term energy production by photovoltaic solar parks (PVSP) were considered taking into account specific features of Russian energy market. Based on theoretical simulation using numerical weather prediction results and experimental data it has been shown, that even for low precision techniques their application allows to improve economics of PVSP’s operation. With a decrease in the forecast error by 1.5–2 times, the economic losses due to the grid dispatch schedule deflection decrease by 5–9 times.
