Theoretical Analysis of a Solar PV-Wind Hybrid Power System for Energy Generation in Kutch Region

Abstract

Solar PV-Wind Hybrid Power System that uses renewable sources to supply power to grid to meet the power requirement. Theoretical Mathematical Modeling and its Generation analysis showed that solar radiation and wind are the most important physical variables for the Solar PV-Wind power system design. The study proposes Solar PV-Wind based system, affordable by local government standards to respond to the electricity demand of that state, is the one with an irradiance between 2.6 to 7 kWh/Day/m2 and wind speed between 6.6 to 15.5 miles per hour. The annual average daily yield, annual average monthly yield and total average Capacity Utilization Factor (CUF) are 5 kWh/kWp/Day, 157 kWh/kWp/Month and 21 % Respectively for solar pv-wind hybrid power system total Generation for Kutch region. The model shows that with the help of Solar PV-Wind Hybrid Power System we can forecast the energy generation of minimum 30 % and maximum 70 % energy generation which can be utilize in state with the modification of existing infrastructure hence infrastructure cost can be saved and waste land between the wind mills can also be utilized.

“…Total solar irradiance (radiation) on the tilted surface of the solar module includes reflected, direct, and diffuse radiation (Weatherspark, 2015;Torrentpower, 2015;Desai et al, 2020a;Desai et al, 20212021;Desai et al, 2020b;Sharma and Goel, 2017;Desai et al, 2019;Desai et al, 2021a).…”

“…Using an empirical equation, we can measure the beam, direct, and diffuse radiation or estimate the total solar radiation falling on the solar module. Month wise, daily average monthly global radiation on a horizontal surface H ga is given by (IRENA, 2012; Sharma and Goel, 2017;Desai et al, 2019;Desai et al, 2020b;;Desai et al, 2021a;Desai et al, 2021b;Bihari et al, 2021;Desai et al, 20212021).…”

“…The PR value generally varies between 60 and 80%, but it depends on the solar PV module temperature, DC cable loss, soiling losses, AC cable loss, transmission loss etc. PR is defined as the ratio of the final yield (Y f = total energy fed to the grid) to reference yield of the total energy (Y r ) that the system could have produced without any losses in ideal condition (IRENA, 2012;Sharma and Goel, 2017;Desai et al, 2019;Desai et al, 2020b;Desai et al, 2021a;Desai et al, 2021b;Bihari et al, 2021;Desai et al, 20212021).…”

“…where NOCT = nominal operating cell temperature, T amb = ambient temperature, Gt = total solar irradiance in plane (IRENA, 2012; Sharma and Goel, 2017;Desai et al, 2019;Desai et al, 2020b;Desai et al, 2021a;Desai et al, 2021b;Bihari et al, 2021;Desai et al, 20212021).…”

“…E f = energy from the front side (kWh), E r = energy from the rear side (kWh), A t = total solar panel area (m 2 ), η pvf = rear efficiency of the solar module (%), η pvr = front efficiency of the solar module (%), H ga = average annual solar radiation on the shadow free solar module, H ga = average annual solar radiation on the solar module due to albedo, PR = performance ratio (generally vary in the range between 0.5 and 0.9, default value = 0.75) (IRENA, 2012;Sharma and Goel, 2017;Desai et al, 2019;Desai et al, 2020b;;Desai et al, 2021a;Desai et al, 2021b;Bihari et al, 2021;Desai et al, 20212021) Total Bifacial Energy Yield…”
