摘要
智能电网以自愈、清洁、经济等优点成为了今后电网发展的一个重要趋势。随着常规能源的日益减少,风力发电将会在智能电网中起着越来越重要的作用,但是风电无法像常规电源一样由输电网调度中心集中调度和控制,需要一种新的并网方式解决风电输出功率波动而带来的频率和电压的偏差。提出了一种把风电以微网的形式并入智能电网的策略,在Matlab/Simulink的环境下进行了仿真,仿真结果证明了所提出方法的可行性和有效性。
mart grid,characterized by many advantages such as self-healing,lean and economic,has become an important trend of power grid development.Along with the decrease of conventional electrical sources day-by-day,wind power generation will play a big role in smart grid.But it is impossible to regulate them by dispatch center of transmission network like conventional electrical sources.So it needs to study new strategies to overcome the frequency and voltage deviation caused by the generated output power fluctuation.This paper proposed a new method to connect wind turbine generator into smart grid by the form of microgrid.The studies reported in this paper are based on time-domain simulations in the MATLAB/Simulink environment.And the results show that the proposed method is feasible and effective.
