Development of an improved microgrid-centralize power sharing scheme using fuzzy logic controller

A microgrid is a local energy grid with control capability, which means it can be connected to or disconnected from the traditional grid and operate autonomously. Recently, the droop control techniques are widely used to solve the problem of load sharing in microgrid system. These techniques have be...
