Universal power line manager for micro grid

In micro grid many power quality issues like voltage sag, swell, power frequency variation, and harmonics are present. This paper proposes a new power line conditioner called Universal Power Line Manager for micro grid. The power circuit of a general universal power line manager (UPLM) is based on the combination of UPQC, UPFC and frequency changer (matrix converter). This equipment incorporates compensation functions like voltage sag, voltage swell, reactive power compensation, current harmonic rejection, real power flow control, damping the system and also provides frequency regulation. For this integration, the compensator proposed in this paper will be called as the Universal Power Line Manager (UPLM). Simulation results are presented to confirm that the new approach has better performance over the existing power quality conditioners in micro grid.
