Abstract

the objective of this paper is to propose a multi-input transformer coupled DC-DC converter for a stand-alone hybrid system consisting of PV and wind in rural areas where access to the main grid is not reliable. The locally available renewable energy sources are integrated into a system to accomplish the needs of the rural community with energy-efficient DC technology. The propound converter consist of a bidirectional buck-boost converter which harness power from the PV panel along with battery control and a transformer coupled boost half bridge converter which harness the power from the wind. The suggested architecture is more advantageous to the current stand-alone topologies as it has less component count, reduced power conversion stages and lesser losses. These characteristics enhance the efficiency and reliability of the presented scheme. MATLAB/Simulink studies are performed to acquire simulations for the different operating modes of the proposed control strategy.

用于可再生能源农村电气化的多输入变压器耦合DC-DC变换器

本文的目标是提出一种多输入变压器耦合DC-DC变换器，用于接入主电网不可靠的农村地区的独立光伏和风能混合系统。将当地可用的可再生能源整合到一个系统中，以节能直流技术满足农村社区的需求。该逆变器由双向降压-升压逆变器和变压器耦合升压半桥逆变器组成，前者利用来自光伏面板的电力以及电池控制，后者利用来自风力的电力。所建议的架构对当前的独立拓扑更有利，因为它具有更少的组件数量、更少的功率转换阶段和更小的损耗。这些特点提高了方案的效率和可靠性。采用MATLAB/Simulink对所提出的控制策略的不同工作模式进行了仿真。
