“…The rotational kinetic energy of the wind turbines is utilized to supply virtual inertia, but it is not suitable for other kind of RES such as the PV generation. In [17], a virtual inertia control strategy analogized with VSM is presented to enhance the inertia of the DC microgrid. However, an auxiliary control loop to emulate VSM characteristic has to be added in the converter control system.…”

“…The efficient tuning of the voltage controlled distribution generation forward gain can increase the microgrid damping factor and improves the dynamic response of the complete system. In [112], a control method for microgrid with bidirectional converters analogized and virtual synchronous machine to improve the inertia of microgrid and to confine the voltage variation of dc bus is proposed. The study in [113] presents the complex microgrids and designed the sliding mode type advanced control approaches to control them.…”

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.

“…Because of these limitations, new control laws are needed in order to emulate the inertia effect. This subject has been widely discussed in the literature, which has led to the development of the grid forming control [5]- [6] that induces more natural inertia effect linked with the way to synchronize the converter to the grid. This has been largely documented on various publications dealing with virtual synchronous machine, synchronverter, virtual synchronous generator (VSG) or VISMA [7]- [13].…”

The virtual synchronous machine concept (VSM) has been developed initially to reproduce the synchronous machine stabilizing effect by providing inertia with the emulation of swing equation, whereas droop control is developed initially to ensure load sharing and has no inertia. An introduction of a low pass filter to droop control has been motivated to filter the active power measurement and ensures a time decoupling with the inner control loops, whereas, this low-pass filter can also provide inertia to the system. This functionality is limited due to its negative impact on the active power dynamic. This paper proposes an analysis of the conventional droop control by showing its limitations and proposes an improved inertial droop control that allows providing the inertia to the system and ensures a good dynamic behavior of the active power at once in simple manner, and without modifying the load sharing capability. The results obtained are compared to the conventional method (Droop control and VSM) in various topologies in order to show the relevance of the proposed method.
