Operation assessment of a wind generator with a conventional power system

Injection of wind power into an electric grid affects the voltage quality. As the voltage quality must be within certain limits to comply with utility requirements, the effect should be assessed prior to installation. To assess the effect, knowledge about the electrical characteristics of the wind turbines is needed otherwise the result could easily be an inappropriate design of the grid connection. So, this paper aims to operate wind generator with conventional power system at some of areas of Egypt such as Egyptian coastal on Red and Mediterranean seas, Toshki and East of Oweinat that show significant promise for wind energy exploitation. Firstly, the dynamic performance of a wind-turbine synchronous generator supplying an infinite bus-through a transmission line is study. Also, a linear model for this system is developed and proportional plus integral controller is designed. This controller is examined for some disturbances in wind speed, load and short circuit faults, and the results are compared with the open loop ones. Then, a proposed approach has been introduced to assess the energy credits of the study of wind energy system as a function of wind-turbine, generator and installation site characteristics. Also, the energy output of this wind-generator has been assessed economically to compete with conventional power systems (CPSs). Finally, the proposed approach is used to evaluate the operation of the study of wind-generator with CPSs in number of applicable applications in Egypt.
