Accurate estimation of communication bandwidth is critical for the sensing and controlling applications of smart grid. Different from public network, the bandwidth requirements of smart grid communication network must be accurately estimated in prior to the deployment of applications or even the building of communication network. However, existing methods for smart grid usually model communication nodes in coarse-grained ways, so their estimations become inaccurate in scenarios where the same type of nodes have very different bandwidth requirements. To solve this issue, we propose a fine-grained estimation method based on multivariate nonlinear fitting. Firstly, we use linear fitting to calculate the convergence weights of each node. Then, we use correlation to select the important characteristics. Finally, we use multivariate nonlinear fitting to learn the nonlinear relationship between characteristics and convergence weight, and complete the fine-grained bandwidth estimation. Our method exploits multiple node characteristics to reveal how different nodes affect bandwidth requirements differently, and it can learn multivariate estimation parameters from present network without human interference. We use NS2 to simulate a real-world regional smart grid. Simulation shows that our method outperforms existing works by up to 56.5% higher estimation accuracy.
