Abstract :
The control paradigms of the DG sources in the smart grid are realized by either utilizing Virtual Power Plant structures or by employing MicroGrid structures. Both Virtual Power Plant and MicroGrid are presented with the problem of control of power flow between their comprising DG sources. This paper depicts this issue in Virtual Power Plant control structures and proposes a control methodology for the flow of active and reactive power, which is applied to the DG sources interfaced electronically (inverter) in the Virtual Power Plants. The proposed controller develops and utilizes the virtual active and reactive power control variables to control the active and reactive power independently for a medium length transmission line model. Moreover the proposed controller is successfully applied on all values of resistance and reactance for the medium length transmission line. The current paper details the control technique by first presenting the mathematical and electrical network analysis of the methodology and then successfully implementing the control using Matlab-Simulink Simulation.
