Effect of the generation mix on wind power introduction

The specific needs and ensuing costs for wind power integration into electricity generation systems depend to a large extent on the operation, composition and behaviour of the electricity generation system. The differences in the considered systems greatly influence the outcomes regarding wind power integration. The generation mix is studied here. Analyses are performed using a mixed integer linear programming model so as to get more insight in the consequences of the design and operation of electricity generation systems including wind power by looking at three distinct case systems. The model takes into account a multitude of technical specificities of the operation of an electricity generation system. The results show several aspects that are strongly related to the composition of electricity generation systems that influence the integration of wind power in the systems. These aspects range from the composition of the system to more specific technical parameters of the power plants and their operation, such as the marginal power plant and the greenhouse gas emission levels. The results shed some light on the reasons for the divergence in wind power integration studies. Moreover, it can help in gaining insights in the future development of electricity generation systems where wind power is being introduced.
