“…The proposed controller can re-duce the unstable generation negative influences to below the level of the system load. In [48], a modest method to synergistic control of distributed energy sources in low voltage microgrids is presented. This method can use the full capacity of distributed energy sources during islanded and grid-connected operating modes.…”

The power demand with interest in green power has focused researcher to develop the distributed power generation using wind energy, solar energy, etc. With the fast depleting fossil fuel reserves, energy security and environmental concerns there is a huge requirement of alternate sources of energy to fulfill the present energy demand. Distribution generating system can support the weak grids, maintaining grid power, managing balance power and enhancing the power quality. Any research work base depends on the literature survey and the studies carried out by several kinds of research and their support to research field encourages for more scope of research. The important advantages related to microgrids have led to huge efforts to grow their dispersion in the power systems. While microgrid is fast growing but there are still various challenges to efficiently control, design, and operate microgrids when linked to the main grid, and also when in islanded mode, where wide research actions are ongoing to handle these issues. This paper presents a review of issues concerning integration of renewable energy sources to microgrids and offers a description of research in areas related to economic feasibility of microgrids system, including dynamic analysis of microgrid hybrid system in grid-connected mode, application of power electronics, microgrid operation, and control.

“…The UI is always controlled as a voltage source and, in general, it performs as a grid-supporting voltage source during grid-connected operation and as a grid-forming voltage source during islanded operation [15]. A communication infrastructure is assumed to provide the narrowband communication link between MC and distributed EGs that is needed to implement the coordinated control by the power-based algorithm [16]. It is worth remarking that the use of communication is limited to microgrid's optimization functions; if communication failures occur, the basic functions of DERs, as well as all the functions that can be performed autonomously, keep on operating normally.…”

This paper proposes an effective technique to control the power flow among different phases of a three-phase four-wire distribution power system by means of single-phase converters arbitrarily connected among the phases. The aim is to enhance the power quality at the point-of-common-coupling of a microgrid, improve voltage profile through the lines, and reduce the overall distribution losses. The technique is based on a master/slave organization where the distributed single-phase converters act as slave units driven by a centralized master controller. Active, reactive, and unbalance power terms are processed by the master controller and shared proportionally among distributed energy resources to achieve the compensation target at the point-of-common-coupling. The proposed control technique is evaluated in simulation considering the model of a real urban power distribution grid under non-sinusoidal and asymmetrical voltage conditions. The main results, concerning both steady-state and transient conditions, are finally reported and discussed

The paper presents a microgrid architecture and control allowing full dispatchability of the power generated by distributed energy sources. To this purpose, full advantage is taken of power control and energy storage capability of distributed generation units and of the Utility Interface, a gridinteractive power converter equipped with energy storage and located at the point of common coupling. A master-slave powerbased control ensures good efficiency and power quality in the stationary regime, fast dynamic response, full dispatchability, and soft transition from on-grid to off-grid operation, both in case of intentional and non-intentional islanding.
