可再生能源在欧盟未来的能源框架中扮演着重要角色。到2020年,在欧盟总的能源消耗量中,预期20%将来自可再生能源,并且能效将提高20%。智能电网将是未来电力系统接纳大规模可再生能源发电并网的基石。文中介绍了欧洲的可再生能源开发现状和规划以及能源政策,并讨论了欧盟在智能电网相关技术方面的研发进展。丹麦是欧盟国家中可再生能源使用和相关关键技术研发的领跑者,文中重点以其为例进行介绍和阐述。  相似文献

This paper describes a procedure for simulations of wind power integration in a deregulated power system with two complementary planning tools. The first planning tool is a joint market model (JMM) taking into account the day-ahead market and the regulating power market using 1 h average time steps. The second tool is the stepwise power flow (SPF) model simulating the frequency deviations and power balancing within the hour, e.g. based on 5 min average time steps. Input data is shared by the two tools, and the simulation results from JMM are used in the SPF simulations to ensure consistent results. JMM simulations are performed using two different scenarios for the development in the Nordic power system. The first scenario is the most likely development for 2010, and the second is a high-wind scenario assuming 10% of the electricity consumption in the Nordic countries supplied by wind power. Subsequently, a worst case 1 h period is selected from the JMM simulations, converted to the more detailed grid representation in SPF, and finally simulated and analysed with SPF.  相似文献
