Renewable energy sources (RES) have been gaining an increasing importance in recent years. However, the integration of these resources into the current distribution systems is considered a challenging task due to two limitations. These two limitations are the cost of equipment and the intermittency of the generated electrical power. Distributed generation of wind-photovoltaic hybrid systems connected...
In recent years, renewable energy sources (RES) has increased all over the world, especially in Europe, and the changes brought by these sources have a significant impact on system performance and efficiency. Integrating RES to an electric power network offers many techno-economical benefits and in the same time necessitate advances in the operation, control and planning of electric networks. This...
The integration of renewable energy sources such as wind power into power systems is quite difficult due to their stochastic nature. As wind power penetration begins to reach significant levels these difficulties can mean great financial expenses and increased carbon emissions. In this paper we demonstrate that through smart utilization of multiple generation sources, a technique we call integrated...
Wind energy is one of the most popular sources for renewable energy. Worldwide, but especially in Germany, an extensive growth of installed wind energy plants can be traced. In Germany, the installed power of wind energy plants in 2007 was about 22 GW. The aim of the government is to raise this amount to 47 GW to the year 2020, what will be equal to 60 % of the total load of Germany. One problem is...
