摘要
频率稳定是维持微电网孤岛运行的关键因素。需求响应技术的应用为孤岛微电网的频率控制提供了新方法。针对孤岛微电网频率稳定问题,文章提出一种考虑调频效益的源-荷协同频率控制策略,使可控负荷与新能源共同参与微电网频率调整。最后,在Matlab软件中搭建了微电网模型,仿真结果验证了文章计及调频效益下的源-荷协同频率控制策略的有效性,使微网调频时的功率分配更合理。
The frequency stability of the microgrid is the key factor to maintain its stable operation under island state.The application of demand-side response technology provides a new solution for the frequency control of the isolated microgrid.Focusing the problem of frequency stability of island microgrid,a source-load cooperative frequency control strategy considering the benefits of frequency modulation is proposed,so that the controllable load and new energy can participate in the frequency adjustment of the microgrid.Finally,a microgrid model is built by Matlab software.The simulation results verify the effectiveness of the source-load cooperative frequency control strategy that takes into account the benefits of frequency modulation in this paper,which makes the power distribution during frequency modulation more reasonable.
