Abstract


This paper performs a comprehensive survey on power flow control scheme and is applied to a single-phase hybrid energy system. The survey is made based on the performance of the system during operation in islanding and grid-tied modes. It covers the coordination of control strategies and the stability and the efficiency of the controller techniques among the hybrid systems. At the same time, the system must be able to stabilize the voltage level as well as to control the flexibility of power flows. Therefore, this review is based on droop control concept and has been coordinated with adaptive and robust control mechanisms. The importance of these controllers is to see the adaptability to various conditions practically, such as disconnection of transition of those modes whenever there are dynamic changes to the hybrid system. For this reason, the droop control scheme must able to fulfil the performance requirements to achieve faster and smoother transition associated with islanded and grid configurations. Moreover, it also should provide an effective system performance in terms of setting up the power control strategy to manage the power flows among the inverters connected to local loads. As a conclusion, this paper has tabulated several important tables on the variety of droop control techniques that are suitable for different case systems for the hybrid-islanded-grid connection. As an ultimate goal, it is also to provide information covered from the system configuration to choose the right controller that can balance the power in the system and generate a continuous load voltage waveform during transient.
