摘要

考虑将各种分布式能源组合成一个整体系统，既可以独立运行，也可以与主电网协同运行。该模型是由光伏电池和燃料电池组成的并网混合系统。动态电压恢复器(DVR)是一种用于保护系统免受电压突然变化的装置。由于DVR注入了所需的补偿电压，系统中引入的电压下降/膨胀可以通过DVR进行补偿。利用MATLAB/Simulink建立了各部件的模型并将其组合成混合系统，并对其波形进行了研究。然后利用提出的DVR控制策略对电压进行了控制分析。通过MATLAB仿真研究验证了所提方案的有效性。

Voltage compensation in a grid connected hybrid system using Dynamic Voltage Restorer

Asmall scale power grid combining various distributed energy resources to form a whole system that can operate independently or in conjunction with the main grid is considered. Proposed model is a grid connected hybrid system consisting of photovoltaic (PV) cells and fuel cells. Dynamic Voltage Restorer (DVR) is a device used to protect the system against sudden changes in voltage. Voltage sag/swell introduced in the system can be compensated using DVR as it injects required amount of compensating voltage. Models for each component are developed and combined to form the hybrid system using MATLAB/Simulink and waveforms are studied. Then control in voltage is analysed using proposed DVR control strategy. Proposals are validated through simulation studies using MATLAB.
