A Multi-Port Autonomous Reconfigurable Solar PV System for Renewable Energy Integration in Hybrid AC/DC System

System voltage stability in a transmission system with ac grid and HVDC links can be improved by multi-port autonomous reconfigurable Solar system (MARS) by connecting photovoltaic (PV) and Battery Energy Storage systems (BES). A Bifred converter is implemented to improve the dc voltage from the PV arrangement and a Grey Wolf optimized adaptive neuro fuzzy inference system (GWOANFIS) are employed to regulate dc/dc converter output. Solar PV output is influenced by climatic conditions, availability of sunlight, and temperature, hence a suitable storage battery is necessary toward the storage of the excess electricity generated. The Lithium ion (Li-ion) battery accomplish as a power reserve and it maintains energy balance and enhances the trustworthiness of the power system. The bidirectional converter connects the battery to the HVDC link and has a bidirectional power flow dimensions and enables the operations in buck and boost mode. The proposed technique is simulated using MATLAB/SUMULINK, and the results confirm the behavioral precision of the proposed topology when creating all levels.
