Despacho hidrotérmico de corto plazo : herramienta computacional, en lenguaje python, para la solución del despacho hidrotérmico de corto plazo considerando la red eléctrica.

Abstract

In this curricular integration work a computational tool is developed, in Python language, for the solution of the Short-Term Hydrothermal Dispatch problem (DHT-CP) considering the electrical network in power systems. For the calculation of active power losses in the electrical network, AC power flow is used. The mathematical formulation of the technical and non-technical constraints of the problem is included. Two methods are implemented in the computational tool for the calculation of the power generated by hydroelectric power plants. The computational tool is applied to the IEEE 14-bus system and the Ecuadorian National Interconnected System (SNI); for the SNI two study cases are studied according to its hydrology: dry season and rainy season. The tool provides optimal results for the power generated by each power plant as a function of time, where the objective is to minimize the generation costs of the thermal power plants; in the program the different restrictions of the problem can be activated or deactivated and the results are shown graphically and reported in tables in Excel format.
