Optimal Energy Dispatch Analysis Using the Inclusion of Virtual Power Plants Based on Dynamic Power Flows

The growing manifestation of non-conventional renewable energies, in modern electrical power systems, creates a great challenge on the normal operation of the system and planning the dispatch of active power, in economic terms. In order to achieve the objective of economic dispatch and be competitive in the electricity market, the concept of virtual power plant (VPP) has been introduced. It considers electrical elements and equipment with the aim of working as a single set that generates economic and operational benefits to the electrical system, taking into account the features and restrictions for an energy dispatch scenari0. This paper proposes a case of study that considers the use of a virtual power plant in order to analyze the effects caused along the network. The optimal dynamic flow of AC power (ODFAC) uses a non-linear programming algorithm and how it is affected not only for the restrictions of the electrical elements and equipment but also for the restrictions of the topology and formation of the electrical power system. The IEEE 9-bar system is used to illustrate the efficiency of the method, comparing the results of the system with and without the integration of a virtual power plant.
