Abstract
Extension of the main grid to remote areas is economically not feasible. To electrify remote areas, one of the best choices is to install Renewable Energy Sources (RES) as a distributed generation (DG) and thus form a microgrid (MG) in islanded (Stand-alone) mode. In islanded mode, the MG has no support from the national grid. Thus, the overloading of islanded DC MG can collapse DC bus voltage and cause fluctuation in the load. Therefore, the power sharing and the interconnection among the microgrid (MG) cluster are necessary for reliable operation. Many methods for power sharing also aim at minimizing circulating currents which cannot be avoided when every MG feeds their load locally. Therefore, the proper power balancing among generation, loads, and in between MG cluster is challenging in islanded topology. This paper presents an intelligent controller for power sharing among PV-based MG clusters with load management of connected load during power deficiency. The priority is given to the local critical load of each MG. The second priority is given to the remaining load of the respective MG. The least priority is given to the loads connected to the neighboring MGs. The results show that the power continuation to the power-deficient load has been maintained when another MG has surplus power. The circulating current losses between the MG cluster has been fully avoided during no power sharing.

This paper provides load management during power deficiency in MG
Summary
Nowadays, distributed generation (DG) through renewables is a trend to meet the growing electricity demand and to tackle challenges like losses in the long transmission networks, depleting fossil fuel resources, dependency on fossil fuels, and environmental concerns. The extension of the main grid to the remote area is economically and technically infeasible. To address these issues and to electrify remote areas, renewable energy sources (RES) are the best choice for power production as a DG. In RES, a photovoltaic (PV) panels-based power generation system has gained popularity in recent years. For the efficient use of DG, the concept of microgrid (MG) is getting a lot of attention. The MG concept has gained interest due to the easy integration of RES as well as regulatory policies for decreasing tendency in the use of fossil fuel resources [1]
