The Impact of Cloudy Weather on the Operation of Photovoltaic Power Plant in the Northern Part of the Russian Far East

This paper is devoted to studying the working characteristics of photovoltaic plants (PV) in different cloud conditions. A technique for determining the electrical energy efficiency (PV) in different clouds types is described, with graphical explanations of the experimental work procedure. The authors of the paper obtained control parameters for changing the value of the energy generated in a solar power plant under different clouds types, which can be used in operational process modeling and engineering calculations for operating solar power plants. It has been determined that the operation (PV) under different clouds types where the generating capacity of the plant varies in the range (8-95%) compared to the clear sky. The purpose of this research is to use the obtained indicators of changes in the generating capacity of the plant for different clouds types in developing a methodology to assess the clouds effectand their types on the throughput of solar radiation falling on the surface of solar panels.
