The Primary Exploration of Application about Functional Reconstruction and Structure Reconstruction in Microgrid

摘要

This paper confronts the issue that lacking of an efficient way to achieve micro-grid (MG) optimal dispatching and proposes a framework based on the idea of structural reconfiguration and functional reconfiguration to achieve MG optimal dispatching. The multi-functional grid connected inverter (MFGCI) with the function of functional reconfiguration and its control strategy are presented by giving consideration to both MG power quality and the grid connected inverter effectiveness. Aiming at curbing the impact of low efficiency of power output to power grid induced by the cloud shading and non-uniform radiation, a novel dispatching approach is proposed based on the idea of PV array reconfiguration. The proposed MG model is established based on the IEEE 34 bus test feeder system. Simulation results show that effectiveness and feasibility of proposed framework.
