摘要

多功能并网逆变器在改善微电网电能质量方面发挥着至关重要的作用。本文研究了一种电流控制多功能并网逆变器在非线性负载下的暂态和稳态性能，以改善电网电流质量。该多功能并网逆变器结合有源滤波功能，可通过有源功率控制对谐波负载电流、负载不平衡和负载无功功率进行补偿。在自然abc框架下，采用滞环和谐振电流控制器对系统性能进行了分析。在MATLAB/SIMULINK中进行了广泛的仿真研究，比较了两种控制器的特性。

Performance comparison of hysteresis and resonant current controllers for a Multifunctional Grid Connected Inverter

Multifunctional Grid Connected Inverters (MFGCIs) are playing a crucial role in improving the power quality in Micro grids. This paper focuses on the transient and steady state performance of a current controlled Multifunctional grid connected inverter to improve the grid current quality when connected to nonlinear loads. The multifunctional grid connected inverter incorporates active filter functionality and can compensate for harmonic load currents, load unbalance and load reactive power with active power control. The performance of the system is analysed using hysteresis and resonant current controllers in natural abc frame. Extensive simulation studies in MATLAB/SIMULINK were done to compare the features of both the controllers.
