Abstract

The increasing trend in integrating intermittent renewable energy sources into off-grid power system presents major challenges from the viewpoints of reliable operation and control. In this paper, the major problems and challenges in off-grid power system control are discussed, and a review of control strategies and trends is presented. A general overview of the main control is also included. The paper classifies power quality improvement strategies into three levels: primary, secondary, and tertiary, where primary and secondary levels are associated with the operation of the off-grid power system itself, and tertiary level pertains to the coordinated operation of the power system. Each control level is discussed in detail in view of the relevant existing technical literature Irfan Khan | Ameen Uddin Ahmad"Power Quality Improvement in Off-Grid Renewable Energy Based Power System using Different Method" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-1 | Issue-6 , October 2017, URL: http://www.ijtsrd.com/papers/ijtsrd2533.pdf http://www.ijtsrd.com/engineering/electrical-engineering/2533/power-quality-improvement-in-off-grid-renewable-energy-based-power-system-using-different-method/irfan-khan
