Oerview of microgrid management and control

Microgrid is one of new conceptual power systems for smooth installation of many distributed generations (DGs), loads and energy storage system (ESS). The microgrid can operate both in grid-connected and islanded operation mode. The balance between supply and demand of power is one of the most importance means of improving energy efficiency. This paper presents a discussion on the management and control techniques required for microgrid operation in grid-connected and islanded mode. The cooperative control strategy of micro-sources and ESS are also discussed in this paper. Then the strategies are compared based on this applicability with different control requirements.
