Abstract : Microgrids: Configurations, Control, Synchronization and Applications

 This invited talk includes the microgrid configurations, control, synchronization and applications.

These microgrids can also be classified based on energy sources used as two, three, and four energy sources. These microgrids are selected on the basis of power, available energy sources in remote areas and the machine used as the generators for distributed generation units. The PV array is connected to DC bus using a DC-DC converter, whereas, SG (Synchronous Generator), SCIG (Squirrel Cage Induction Generator), SyRG (Synchronous Reluctance Generator), PMSG (Permanent Magnet Synchronous Generator), and PMBLDCG (Permanent Magnet Brushless DC Generator) driven by wind turbines, small hydro turbines, diesel engines and  gas turbines, are connected to the DC bus through the voltage source converters. PMBLDCGs are also connected to the DC bus through a diode rectifier and a boost converter to reduce the control complexity, sensors requirement and the cost. Microgrids are also reinforced with a battery to compensate the output power fluctuations of distributed generation units. A dump load is also connected on the DC bus and controlled to protect the batteries from overcharging and to avoid the impact of the dump load on the power quality of AC bus.
Moreover, the standalone microgrid needs to be synchronized to the main grid for power exchange in case of excess power generation or energy deficit conditions and require voltage-controlled and current-controlled operating conditions, respectively. It implies that the inverter controller requires a change during transitions between these operating modes. Microgrids power institutional campus sites, hospitals, universities, commercial & industrial facilities, remote “off grid” communities, military bases, data centers, municipalities, villages, residential complexes, electric vehicles (EVs) charging stations.

Following are challenges faced by microgrids: (1) interactive mechanism, (2) distributed energy storage mechanism, (3) planning theory, (4) grid-connected control and multi distributed power coordinated control, (5) analysis and control of power quality, (6) comprehensive simulation and analysis and (6) economic operation and energy optimal management.
