Different Power Sharing Techniques for Converter-Interfaced DERs in an Autonomous Microgrid
MetadataShow full item record
A three-level hierarchical control system is considered for microgrids. The microgrid central controller receives the desired ratio for the output power of the available distributed generation units (DG) from the network tertiary controller. It then passes this information to the primary controller of each DG in the form of setpoints. In addition, the central controller receives some information from the DGs or the network and considers them to adjust the setpoints for the DGs. In this paper, the effect of the data transfer delays in the communication system of future microgrids is investigated on the dynamic operation of the distributed energy resources.

Shahnia, Farhad; Chandrasensa, Ruwan; Rajakaruna, Sumedha; Ghosh, A. (2014)In order to minimize the number of load shedding in a Microgrid during autonomous operation, islanded neighbour microgrids can be interconnected if they are on a self-healing network and an extra generation capacity is ...
Shahnia, Farhad; Chandrasensa, Ruwan; Rajakaruna, Sumedha; Ghosh, Arindam (2013)This paper shows how multiple interconnected microgrids can operate in autonomous mode in a self-healing medium voltage network. This is possible if based on network self-healing capability, the neighbor microgrids are ...
Ambia, M.; Al-Durra, A.; Caruana, C.; Muyeen, S.M. (2012)In this paper, islanding operation of a hybrid micro-grid system is proposed with power management control scheme. When micro-grid system undergoes transition from grid connected to the islanded mode, it is required for ...
