This paper is on wind energy conversion systems with full-power converter and permanent magnet synchronous generator. Different topologies for the power-electronic converters are considered, namely matrix and multilevel converters. Also, a new fractional-order control strategy is proposed for the variable-speed operation of the wind turbines. Simulation studies are carried out in order to adequately...
Summary form only given. The paper presents that smart microgrid could offer a perfect power system with higher reliabilities which could guide customers to lower their costs and utilize electricity more efficiently. The task of improving the efficiency and upgrading the resiliency of the electric grid, in order to support clean and renewable energy, is one we cannot let be exported or delegated overseas...
Injection of the wind power into an electric grid affects the power quality. The performance of the wind turbine and thereby power quality are determined on the basis of measurements and the norms followed according to the guideline specified in International Electro-technical Commission standard, IEC-61400. The influence of the wind turbine in the grid system concerning the power quality measurements...
Global climate change threatens to affect many aspects of human endeavor and quality of life, including, of course, in the United States. One such sector is the national power grid, which has been a prominent subject of concern in general with regard to reliability, expandability, and national security. These potential affects on higher-voltage longer-distance electric transmission lines stem from...
With the advance in wind turbine technologies, the cost of wind energy becomes competitive with other fuel-based generation resources. Due to the price hike of the fossil fuel and the concern of the global warming, the development of wind power has rapidly progressed over the last decade. The annual growth rate has exceeded 26% since 1990s. Many countries have set goal for high penetration levels...
As the penetration of wind energy and the size of modern wind farms continue to increase, the voltage control at a specified remote location becomes increasingly important for stable and reliable operation of electric grid. This paper presents a new voltage control scheme that is based on the linear quadratic regulator (LQR) controller formulated as a linear matrix inequality (LMI) problem. The main...
