Abstract

"Small sized synchronous generator based distributed generators (DG) often have low start-up times, and can serve as dispatchable generators in a microgrid environment. The advantage is that it allows the power network to operate in a true smart grid environment. The disadvantage is that such DGs typically tend to have low inertia and the prime movers driving these resources need to be controlled in real time for them to operate effectively in islanded, grid-connected modes and during transition from grid-connected mode to islanded mode and vice versa. When multiple DGs are present in the microgrid, the overall control can become complicated because of the need for sharing the resources. A smart grid environment is then necessary to control all dispersed generation sources in the microgrid. The most common control strategy adopted for multiple DGs connected to a network is droop control. Droop control ensures that the load needed to be served is shared by all the generators in the network in proportion to their generating capability. When DGs operate in a microgrid environment, there is a need for coordinated operation between the DGs, the utility grid and the loads. A MicroGrid Central Controller (MGCC) can keep track of the status from the system standpoint and command the local Microsource Controllers (MC) to ensure system stability. In various modes of operation like grid connected, islanding and during transition, the MGCC can support the MCs by giving them necessary information to contribute towards stable operation"--Abstract, page iii.
