Power quality issues in a hybrid power system

We analyzed a power system network that consisted of two types of power generation: wind turbine generation and diesel generation. The power quality and the interaction of diesel generation, the wind turbine, and the local load were the subjects of investigation. From an energy-production standpoint, producing as much wind energy as possible is advantageous in terms of decreasing the fuel consumption of the diesel engines and reducing the level of pollution. From the customer point of view, good power quality at the receiving end is important. The purpose of this paper is to show the impact of the wind power plant on the entire system. In addition, we discuss how the startup of the wind turbine and the transient condition during load changes affect the system´s voltage and frequency
