摘要

本文提出了一种控制三相电压源变换器(VSC)在复杂条件下工作的新型功率控制结构。VSC输出与LCL滤波器耦合;过滤掉不需要的谐波成分。根据无源元件分数阶特性得到的模型，设计了基于模型的控制器。所提出的控制结构具有自适应性;能够抑制干扰，降低系统的功率、电压和频率振荡;最终根据网格代码得到理想的性能指标。利用MATLAB/Simulink对所提出的功率控制结构进行了验证，然后利用由OPAL-RT控制器和RTDS模拟器组成的硬件试验台进行了实验室实验，将BESS集成到本地配电网中。

Simplified Modelling and Control of Voltage Source Converter Integrated to Renewable Energy Resources

In this article a novel power control architecture is proposed to control a three-phase voltage source converter (VSC) operating under complex conditions. VSC output is coupled with LCL filter; which filters out unwanted harmonic components. Based on the obtained model from the fractional characteristic of the passive elements a model-based controller is designed. The proposed control structure is adaptive; capable of rejecting disturbances, reducing power, voltage & frequency oscillations from the system; eventually results in desired performance Indices as per the grid codes. The proposed power control structure is validated using MATLAB/Simulink followed by laboratory-based experimentation using a hardware test-bed consisting of OPAL-RT controller and RTDS simulator for BESS integration into local distribution network.
