Analysis of the effect of installing 21,8 MW of photovoltaic solar energy at the Contramaestre 110/34,5 kV substation

Abstract

In order to meet energy demand, reduce dependence on imported fossil fuels, and increase the stability and reliability of the Cuban electrical system, a renewable energy development program is being implemented. This paper analyzes the impacts of installing 21.8 MW of solar photovoltaic energy at the Contramaestre 110/34.5 kV substation. For the analysis, the substation was characterized, along with the most important indicators to assess its technical condition. Possible alternatives for connecting the wind farm to the substation were analyzed. The most viable option was installation through lines UU4390 and UU4395, thus ensuring operation within established parameters, improving technical indicators, and increasing the quality of the electrical service provided. This investment saves 9,098 tons of fossil fuels per year, equivalent to USD 5,156 million annually.
