The purpose of integrating a battery energy storage system (BESS) with large scale wind farms is to compensate the intermittency of the wind power and also to make wind farms more dispatchable and competitive against the conventional power plants. This paper presents a novel wind power dispatch control scheme with a BESS based on model predictive control to manage the amount of energy generated and...
Fractional Frequency Transmission System (FFTS) provides a novel approach to integrating the remote wind farm into grid. This approach can overcome the great challenges caused by the randomicity and the intermittence of the wind power. In 2005, the FFTS has been realized for the first time under the conditions of active inversion of phased-controlled cycloconverter, the result of it proves its effectiveness...
Frequency regulation in interconnected networks is one of the main challenges posed by wind turbines in modern power systems. The wind power fluctuation negatively contributes to the power imbalance and frequency deviation. This paper presents an intelligent agent based load frequency control (LFC) for a multi-area power system in the presence of a high penetration of wind farms, using multi-agent...
As wind power achieves higher penetration levels and becomes a more and more substantial portion of our electric energy supply, more stringent requirements are being placed on wind plants. As wind plants displace traditional synchronous generators in terms of percentages, the wind plants must also do their part to maintain stability and reliability of the power system. Modern power electronics are...
Dedicated to high energy-consuming industries, such as chloral-alkali, seawater desalination, and electrolytic aluminum, a novel non-grid-connected power generation (NGCPG) system is proposed; it is composed of a fixed-pitch variable speed wind turbine and a doubly salient DC brushless generator. The configuration of the non-grid-connected power system mentioned is presented. An equivalent model of...
Compared with constant speed constant frequency wind turbine, variable speed constant frequency wind turbine has many advantages: higher efficiency of wind energy converting to electric power, absorbing gust energy, smoothly cutting into the network system, flexible connecting between wind turbine and network system and low operating noise. Currently the variable speed constant frequency technology...
