【 摘 要 】

This paper discusses the current state of DC distribution system, how it can be beneficial to isolate solar-based Micro-Grid (MG) system in a rural area, and how the priority-based approach can help the MGs to operate in cost-effective and reliable ways. DC distribution system holds many advantages over AC systems in such area, where the load demand is not so high and the electricity supply through grid extension is not feasible. Direct load control-based approach can ensure a continuous supply of power to the loads with various priorities. In this paper, an experimental analysis of the DC MGs has been presented with the help of priority based algorithms. A cost-effective SCADA system is developed to interface with the remaining parts of the system, so that the MGs can be monitor and control to get the desired performance. The main objective of this study is to identify a cost-effective and practical energy management system for the rural area, where expensive and advanced technology is not suitable. From this study, it is concluded that the proposed combination of algorithm and SCADA system increase the system’s reliability and power consistency significantly.
