In this work, we will develop models for fuel cells and power converters for a parallel grid-connected operation, and study the stability of the system. Furthermore, we will develop control strategy for the parallel operation of distributed generation systems (DGS) in a standalone AC power supply, and control algorithms that will facilitate only low-bandwidth data communication signals between each generation system Furthermore a combined voltage control loop using Perfect Robust Servo-Mechanism and Discrete Time Sliding Mode current controller will be designed for each converter to ensure low THD output voltages. The voltage control loop will be designed to allow a harmonic control droop scheme that ensures proper sharing of harmonic components of load currents. Simulation studies using two parallel three-phase PWM inverters (600 kVA) will be developed to show the effectiveness of the proposed control. The control methods will be implemented at OSU 5 kva experimental test bed.

在这项工作中，我们将开发模型的燃料电池和功率转换器并联并网运行，并研究系统的稳定性。此外，我们将开发分布式发电系统（DGS）在一个独立的交流电源并联运行的控制策略，和控制算法，将促进只有低带宽的数据通信信号之间的每个发电系统此外，一个组合的电压控制回路，使用完美的鲁棒伺服机制和离散时间滑模电流控制器将被设计为每个转换器，以确保低THD输出电压。电压控制回路的设计将允许谐波控制下垂方案，确保负载电流的谐波分量的适当共享。使用两个并联的三相PWM逆变器（600千伏安）的仿真研究将被开发，以显示所提出的控制的有效性。控制方法将在OSU 5kva实验台上实施。
