N. Chitra, K. Prabaakaran, A. Senthil Kumar, Josiah Munda . Ant Colony Optimization Adopting Control Strategies for Power Quality Enhancement in Autonomous Microgrid. International Journal of Computer Applications. 63, 13 ( February 2013), 34-38. DOI=10.5120/10529-5513
Microgrid has comes out one of the key spot in research on distributed energy system. Since the definition of Microgrid is paradigm by the first time, investigation in this area is growing continuously and there are numerous research projects in this moment over the world. This paper mainly focused on Power quality improvement in autonomous microgrid. Herein an optimal power control strategy for an autonomous microgrid is carried out in a real time self tuning method. Voltage frequency (Vf) regulation and Harmonic analysis are the main performance parameter which is consider in this work, particularly from grid connected to islanding operation mode. Especial design of controller scheme is composed of an inner current control loop and an outer power control loop in synchronous reference frame. Ant colony optimization (ACO) is an intelligent searching algorithm, which is applied for real time self tuning of control parameter. The simulation result shows that the proposed controller offers an excellent response to satisfy the Power quality improvement.
