Optimal coordination of wind and hydro power plants in power systems

Due to the growing integration of distributed generation sources (DG) into electrical power systems, it is important to acquire knowledge concerning their operation characteristics. An important aspect is the volatility nature of these sources, especially wind sources. Thus, it is necessary that the electrical system in which this type of DG sources are included, be able to compensate each variation in the electrical energy production, to maintain all the time a balance between production and consumption, in compliance with requirements imposed by the system operator. This study presents the influence of coordination of the wind and hydro power plants, on power losses in electric power systems, based on the correlation between electrical energy productions of these. The results show the effectiveness of the proposed method.
