Despacho óptimo de energía en plantas virtuales de generación basado en flujos dinámicos de potencia

Abstract

The growing presence of non-conventional renewable energies within modern electrical power systems, generates one of the greatest challenges in planning the optimal dispatch of active power economically and appropriately for the normal operation of the system. To achieve the goal of dispatch and that non-conventional renewable energies can compete within the electricity market, the concept of virtual generation plant (VPP) which considers for its training electrical elements and equipment, communications systems, management system of energy, control system, energy storage system and the stocacity of energy sources such as solar and wind, to work as a single set that generates economic and operational benefits managing to comply with characteristic characteristics and restrictions of an electrical power system. Establish a scenario that considers the entry of a virtual generation plant and subsequently analyze the effects caused, it is proposed to analyze the problem with dynamic flows of AC power. The optimal dynamic flow of power AC (DOPAC) uses a non-linear programming algorithm and is subject to both the characteristic restrictions of the elements and equipment electrical, as to the restrictions of the topology and formation of the electrical power system; In addition, the variable dynamics of the resource is considered in energy sources considered to be solar and wind. The IEEE 9-bar system is used to illustrate the effectiveness of the method compared the results of the system with and without the integration of a virtual generation plant. The results obtained show that the entry of a VPP to the electric power system manages to minimize generation costs in certain periods of time depending on the availability of energy resources
