Abstract

This paper presents the design and implementation of a solar-grid hybrid system that provides an economical and sustainable power supply to the dc loads. Integration of solar system with grid is quite complex and expensive. Yet with this proposed design not only a cheap and simple hybrid system can be achieved but also a reliable, efficient and cost effective one. A charge controller is designed with maximum power point tracking technique using perturb and observe method. The output of the charge controller is connected to one of the input of diode switching circuit. As the loads are considered to be DC only, the AC power supply from the grid is converted to DC by an AC/DC converter and this dc output is connected to the other input of diode switching circuit. This diode switching circuit decides what percentage of solar and grid current are to be delivered to the load. This incorporation of solar and grid system is analysed and observed to see to what extent we can reduce dependency over grid, to save energy and promote usage of green energy by implementing this simple hybrid system.

带MPPT充电控制器的并网混合太阳能系统

本文介绍了一种为直流负荷提供经济、可持续供电的太阳能电网混合系统的设计与实现。太阳能系统与电网的并网是一项复杂而昂贵的工程。然而，通过这种设计，不仅可以实现便宜、简单的混合动力系统，而且可以实现可靠、高效和经济的混合动力系统。采用摄动观察法，设计了最大功率点跟踪技术的充电控制器。电荷控制器的输出端连接到二极管开关电路的一个输入端。由于负载只考虑直流，来自电网的交流电源通过AC/DC转换器转换为直流电源，该直流输出连接到二极管开关电路的另一个输入端。这个二极管开关电路决定太阳能和电网电流的百分比将被传递给负载。通过对太阳能和电网系统的结合进行分析和观察，看看我们可以在多大程度上减少对电网的依赖，通过实施这个简单的混合系统来节约能源和促进绿色能源的使用。
