In some regions, for example in Northwest and Northeast China, Northern Germany, Denmark, Spain, Portugal, Ireland or Texas, RE generation supplies a significant amount of the total energy demand. In the future, more and more countries are likely to experience similar situation as RE generation is increasingly considered not only as a means to reduce CO2 emissions, but also as an interesting economic alternative in areas with appropriate RE resources. However, RE generation delivers a variable level of power depending on the wind speed, and is not dispatchable in the same way as conventional energy sources due to the special characteristics. The integration of high penetration level of RE generation in some regions has brought much challenge on maintaining power system reliability and the balance between load and generation. Since the power system were originally designed around large-scale synchronous generators, new approaches and solutions are required when RE generation is integrated into power system with high penetration. This paper provides an introduction about the special characteristics of RE generation, and tries to explore potential challenge caused by the integration of RE generation into power systems. In addition, this chapter will focus on wind and solar power considering their high share in RE generation.
