Power output evaluation of a wind–solar farm considering the influence parameters

Abstract

Abstract Power generation from a hybrid wind–solar farm depends on several parameters such as farm location (solar radiation, wind direction, wind speed), layout of farm, shadowing effect and ambient temperature. Based on the location, the hourly uncertain wind speeds and solar radiation are estimated using Kernel density estimation. An irregular crossed wind farm layout is considered for study as it reduces the effective wake effect, produced due to upstream wind turbines. Further solar panels are also fitted onto the wind farm in order to increase the power output using the same land. In this work, the wake analysis includes single as well as multi‐wake model. The output of the solar farm is affected by many parameters like irradiance, wind speed, atmospheric temperature, self‐shadowing of consecutive photovoltaic (PV) panels and turbine shadowing on PV panels. The power output from solar is calculated considering the temperature effect on PV cell, effect of wind speed on solar panel, self‐shadowing of PV panel and shadowing effect of wind turbine on solar panel.
