Hourly model of a Combined Cycle Power Plant for SimSEE

Wind and solar power installed in Uruguay exceeds demand average and generates around 45% of the country's energy (year 2019) [1] . The operation of the system must be very agile and one important point is to consider the flexibility of the different resources for monitoring variability. Under these conditions, optimal system management depends on the ability to anticipate energy generated by these sources. Recently (11/11/2019) Punta del Tigre Combined Cycle Plant was inaugurated in Uruguay, this plant has a power of 540 MW ( https://portal.ute.com.uy/noticias/ciclo-combinado-respaldo-menor-costo ), this is 26% of the biggest historical peak of the electric demand of uruguay [1] . Combined cycle plants are preferred in new generations of generating power plants to be installed throughout the world. The characteristics of the combined cycle power plants present distinctive advantages over the other existing generation units, such as: high efficiency, relatively short installation times, possibility of operating with various fuels, and are also more environmentally friendly [2] . Modeling and short-term scheduling of these units represents a complicated optimization problem because combined cycle units have multiple operating configurations based on the number and status of combustion turbines (TGs) and steam turbines (TVs).
