In this paper, general concept of a virtual power plant (VPP) and its model is developed. In the proposed model for the VPP, power system is divided into smaller subsystems, and it is called the power system cells. Each cell is a small network that has a control center and management system. The concept of VPPs includes multi-cell power system with aflexible control and management functions for the system. In this paper, in order to model proposed VPP standard system (IEEE 30 bus test system) is used. First, function of each power system cell is defined based on references and constraints and apply the above planning application; MATLAB and General Algebraic Modeling System (GAMS) software have been used until the results load flow and economic dispatch (ED) can be compared. In this project, genetic algorithms (GA) have done optimization of power plants using a cost function and the results compared.
Key words: Virtual power plants (VPP), economic dispatch (ED), micro network, load.
