Planeación de despacho óptimo de plantas virtuales de generación en sistemas eléctricos de potencia mediante flujos óptimos de potencia AC

Abstract

The electrical system is in a constant development, referring to the demand required by the user, so the conventional generation does not fully supply the electrical power systems (EPS), and the losses and operating costs are increasing every day, therefore, this research proposes the insertion of virtual power plants (VPP), in order to provide support services to the system and guarantee greater visibility and participation of nonconventional renewable energies (NCRE) which will encompass to a more environmentally friendly transition. Therefore, a heuristic for the dispatch of VPP based on optimal power flows AC (OPF-AC) will be implemented in the device. In this way’s seeks to maximize the benefits of VPP, minimize the costs of conventional generation and reduce overloads at peak times assuming the existence of VPP, respecting restrictions of active and reactive power balance, limit of voltages at the nodes and loadability in the transmission lines. All analysis will be performed in a stable state and for validation purposes the 30-bar IEEE test model will be used in which different case studies. Will be analyzed Digsilent Power Factory will be used for EPS simulation, while Matlab and GAMS will be used for modeling and resolution of the optimization model respectively.
