In this paper the virtual synchronous generator control is introduced to MW-Scale Medium Voltage power system. The virtual synchronous generator with its inertia and damping features can be considered as an improvement for the communication-less control method (droop control). The MW-Scale Medium Voltage is generally preferable for its high power density, reduced current level, and reduced losses...
The virtual synchronous generator (VSG) is the interface between distribute generator and power grid, which has the inertia and damping characteristics of the synchronous generator. This strategy can effectively control influence of inverters on power grid. In order to reduce the circulating current and power oscillation, this paper proposed a pre-synchronization control strategy which adds the pre-synchronization...
The virtual synchronous generator (VSG) inverter implemented based on real-time workshop (RTW) is proposed. The design cycle of VSG implemented based on RTW is shown. Consulting the traditional mathematical model of synchronous generator in power system, the virtual synchronous generator model is built in MATLAB/Simulink, and realizing the model conversion to the code automatic. Then the Micro-source...
Dynamic frequency regulation and effect of penetration of static and inertial sources on system stability are important issues for islanded microgrid power quality and reliability. This work presents a novel strategy of utilizing an inverter based source as a voltage source inverter (VSI) or virtual synchronous generator (VSG). Electro-mechanical and power modes are critical for small signal stability...
