摘要
微电网技术的发展能有效地解决分布式发电的接入问题,有利于新能源的开发.太阳能作为最具有利用价值的清洁能源之一,并网光伏发电系统的应用前景越来越广阔.通过利用Mat-lab\Simulink软件,开发出了适用于工程计算的光伏电池模型,基于扰动观察法建立了最大功率跟踪模型,结合空间矢量调制(SVPWM)算法设计出了电压外环-电流内环双环控制结构的逆变器并网控制策略,在此基础上搭建了完整的光伏并网发电系统运行与控制模型.仿真结果表明建立的模型能较好的反映三相光伏并网系统运行特性,为微电网的进一步研究提供了基础.
The issue of distributed generation access can be effectively solved by the development of microgrid, which contributes to make full use of new energy. Solar energy becomes one of the most valuable clean energy, and the application prospects of grid-connected photovoltaie power system is becoming broader. Photovohaie model for engineering calculations is developed, maximum power point tracking （MPPT） module is established based on the perturbation and observation（P＆O）algorithm, and the control strategy of inverter is designed based on the voltage space vector modulation （SVPWM） method with double loop control structure in this paper by using Simulink tools of simulation software Matlab. A grid-connected photovohaie power system operation and control model is built finally. The simulation results show that the model developed in this paper can reflect well the operating characteristics of three-phase photovohaic grid-connected system, and the research provides solid basis for further study of microgrid.
