Despacho económico en sistemas eléctricos de potencia considerando el comportamiento estocástico de centrales de generación a base de energías renovables no convencionales

Abstract

At the present document shows an economic dispatch study throught of non-conventional renewable energies (NCRE), taking into account the sources of wind and solar generation. The analysis is framed in the behavior of the stochastic variables that influence the NCRE at the moment they enter the power system (SEP). To carry out this study, a methodology was developed which first describes a treatment of the data obtained, with the aim of constructing a typical meteorological year (TMY). Second, a heuristic programming model is made for short-term economic dispatch, knowing the behavior of availability of daily resources. Finally, in third place, the results of the methodology were verified, where the stochastic behavior of the NCRE and the demand in the SEP was very variable, but knowing at what time of the day of a TMY the resource is most used; Starting from that point, the DC flow was applied and, respectively, the economic dispatch (lambda-iterative) where the contribution is analyzed at the time of covering a daily random demand. Knowing the behavior of NCRE, schedules of greater contribution are specified and with this an operational plan can be elaborated in the generation system.
