Abstract
With the development of new energy and micro grid, inverter plays an important role as the interface of distributed new energy to realize power conversion. However, the introduction of various power electronic components not only enhances the response speed and flexibility of the micro grid, but also greatly reduces the overall inertia of the system. VSG control technology is introduced in this paper. At the same time, through the in-depth analysis of energy storage system, the inertial parameters of energy storage system are deduced. The VSG control and the energy storage system inertial parameters are matched to increase the system inertia and damping. Aiming at the power response part of multi-machine system, the inertial parameters of multi-machine system are controlled uniformly, which makes the whole system achieve good power response and distribution. At last, a simulation model was set up by MATLAB for verification and analysis.
