Control Strategies for Microgrids: An Overview

This paper presents An overview control strategies in microgrids. Microgrids are a reliable alternative whenautonomous power supply is needed, such as on islands, or when optimizations are required for higher level grids or supplycosts. With grid-connected operation, microgrids enable energy to be reliably provided from renewable sources, at bothhigh-peak and low-peak times. They can also influence reactive power and save money by regulating the maximum powerdemand or infeed. Microgrids offer high reliability and improved energy quality. And they have a further advantage:Microgrids can operate independently of the higher-level grid. Reliable monitoring and control are the biggest challenges tostable operation of a microgrid. Microgrid Control meets these challenges.
