| 英文摘要 |
| Virtual synchronous generator (VSG) can mimic the operating mechanism of the synchronous generator,
which can provide inertia and damping support for system. In islanded mode, parallel-connected VSGs mainly use decentralized
droop control and the system is not able to restore frequency or reasonably share active power. To solve these
problems, a distributed control strategy of parallel-connected VSGs based on consensus algorithm is proposed. The control
strategy can improve the frequency and active power characteristics of the system. The mathematic model of traditional
VSG control is firstly demonstrated. Based on that, the whole control scheme of frequency restoration and active power
sharing for parallel-connected VSGs is established. With distributed control strategy, the scheme utilizes distributed communication
network exchanging few information between neighbor VSGs to make the system restore frequency to nominal
value and reasonably share active power to satisfy different demand. Simulation results verify the validity and effectiveness
of the proposed control strategy. |
