摘要 针对微电网配有新能源储能装置并网运行时电源的频率扰动问题,设计了一种基于虚拟云计算控制方法的微电网电源云计算系统,并对其电源配置问题进行分析。结合IEEE30微电网模型,以分布式电源频率稳定量为目标函数,将虚拟云计算控制转化为多约束条件的非线性规划,考虑状态及控制变量约束条件,仿真研究了不同光-风接入比的电源配置。研究结果表明,在较佳的新能源电源配置下,该虚拟云计算系统可显著提高IEEE30微电网频率的稳定性。 Aiming at the frequency perturbation problem of power supply when the micro grid was connected with a new energy storage device,a micro grid power cloud computing system based on virtual cloud computing control method was designed,and its power configuration problem was analyzed.Combining with the specified IEEE30 micro grid model,the amount of frequency stability of distributed generation was taken as objective function,and the virtual cloud computing control was transformed into the nonlinear programming with multiple constraints.The power configuration of different light-wind access ratio was studied by simulation considering the state and control variable constraints.The study result shows that the frequency disturbance of the IEEE30 micro grid model significantly for a optimal new energy power supply configuration can be improved by the virtual cloud computing.
