Thermal power plant cooperation with wind turbines

Abstract. The popularity of wind energy is increasing and that arises several technical problems like system stability and wind power reliability. Power companies have learned how to predict power consumption and therefore know how to plan power generation. Adding notable amount of wind power into the system requires a new approach to system stability. The idea of wind power is to reduce the domination of fossil fuel and to decrease emissions. This issue is very important in Estonia, where mainly thermal power plants are used for power production. In this paper cooperation between wind turbines and a conventional power plant is analysed. As the result of this analysis, the supplementary emission caused by using conventional power plants for balancing wind turbines is calculated. Key words: wind turbines, partial load, emission reduction, gas engine power plant
