Average-model based VSC是什么

Average-model based VSC (Virtual Synchronous Converter) 是一种电力电子转换器控制策略，用于将电力系统中的非同步分布式能源资源（如风力发电机和太阳能电池板）与电网连接。它通过仿真同步发电机的特性来使非同步电源仿佛是同步发电机，从而实现了对电压和频率的控制。在这种控制策略中，VSC的输出被设计为一个虚拟同步发电机，其输出电压和频率与电网保持同步。由于其高度可控性和可靠性，Average-model based VSC在现代电力系统中得到了广泛的应用。

Average-model based VSC

Average-model based VSC (Voltage Source Converter) control is a technique used in power electronic systems to regulate the voltage output of VSCs. It involves using an average model of the VSC's behavior to design a control algorithm that can adjust the VSC's output voltage to a desired level.

The average model of the VSC is obtained by averaging the voltage and current waveforms over a period of time, typically a few cycles of the AC voltage. This model is then used to design a control algorithm that can adjust the VSC's output voltage to match a desired reference voltage.

The advantage of using an average-model based VSC control is that it is more robust to changes in the system parameters and can provide better dynamic performance compared to other control techniques. Additionally, it is easier to implement and requires less computational resources.

Overall, average-model based VSC control is a useful technique in power electronic systems for regulating voltage output and improving system performance.
