The study of the characteristics of photovoltaic power stations and the identification of rational operating modes by changing the inclination and the spectral composition of the irradiation

Abstract

The global trends in the development of photovoltaic power stations (PPS) and their application are actively fighting for a place in the sun. On January 20, 2009, Vladimir Putin (at that time the chairman of the government) signed a decree approving the main directions of state policy in the development of renewable energy sources (RES) until 2024, and on May 13, 2019, by decree no. 216 “On the approval of the energy security of the Russian Federation” signed the Doctrine of the energy security of the Russian Federation. In this regard, the need to find the optimal operating modes of PPS has become acute, which is an environmentally friendly way to generate electricity. New designs and methods of using systems are being developed to study and determine the optimal operating modes of PPS. The work justified the design parameters and experimentally investigated the characteristics and operating modes of PPS, determined the effect of the spectral composition of radiation on the amount of generated energy. The study was conducted using graph-analytical processing of the results of practical PPS tests characteristics by simulating outlook surfaces using the biharmonic interpolation method in the Curve Fitting Toolbox application of the MATLAB program.
