Multi-Input Single Output-Quadratic Boost Converter (MISO-QBC) with Independent ANFIS Control of Voltage for Multi-type of Hybrid RES

The primary challenge in using a hybrid Renewable Energy Source (RES) system is the relatively low, unstable output voltage and the regulation of power transfer. Therefore, the interface of converter should be capable of producing a high voltage, maintaining a relatively constant output voltage, and managing load power transfer effectively. In this paper, Multi-Input Single-Output Quadratic Boost Converter (MISO-QBC) with ANFIS control for multi-type of hybrid RES application is presented. The modelling, the design analysis, and the development of the proposed configuration and the independent control structure, along with the simulation, are presented. The control system is capable of regulating the high-voltage DC bus network and the power delivered to the load independently. The proposed system comprises a Fuel Cell (FC) integrated with an independent control system based on ANFIS, alongside photovoltaic (PV) and Wind Turbine (WT) systems. This converter provides high voltage gain up to 25 times. The independent ANFIS control can maintain a relatively constant output voltage of 600 volts with a tolerance of 0.7%. In addition, the control system can manage source power based on voltage availability and load requirements.
