DC grid connected energy flow control formed by three different solar panels, fuel cell and battery-backed hybrid energy generation system

摘要

Hybrid energy generation systems help to increase system reliability and improve power quality. However, they come across some challenges in their widespread using area. These problems are intermittently varying renewable energy sources like solar radiation, high installation costs and limited lifetime of energy storage devices. Thus, there is a need to integrate these sources by means of a suitable power management strategy despite the fluctuations in source and load power. In this paper, an energy system comprising two energy sources, namely PV and fuel cells, is proposed. Each of the energy sources is controlled so as to deliver energy at optimum efficiency. The main aim is to give uninterrupted, efficient and economical energy to consumer. So Arduino microcontroller-based control is applied for energy flow control to DC voltage bus. Also, a complete description of the management system is presented.
