Active Power Sharing in a Micro-Grid with Multiple Grid Connections

This paper presents a mechanism for active power sharing among multiple dispatchable and distributed generation units within micro grid comprising one or interconnections with the main grid. Ideally, should act as constant load voltage source when connected to However, achieve ideal operation, natural variations intermittency of renewable energy sources microgrid need be adequately timely compensated by sources. While several control algorithms have been reported in literature majority proposed methods assumed single interconnection In real world, grids may maintain live links technical operational reasons such reliability, power-dispatch restriction, limitations requirements. Therefore, new method is this paper, which equally effective connections. The robustness examined under different operating conditions. results reveal flexibility adapt various real-world
