“…grid following, grid forming and grid supporting, can be implemented using different hardware structures. Nevertheless, the two-level voltage-source inverter is the most widely used topology [4], [8], [9]. Multilevel inverters are also discussed since they are commonly adopted in literature [21]- [23].…”

“…Those inverters, can also be used to perform power quality enhancement actions by additional control loops [6], [7], which may reduce or even eliminate the necessity of active filters or other devices to fulfill the power quality requirements. Inverters in a microgrid can be implemented by using multiple topologies available in literature; however, one of the most used topologies is the two-level voltagesource inverter [4], [8], [9].

“…Moreover, the energy exchange with the main grid need to be managed to optimize a given cost function, e.g. minimizing the energy cost to the microgrid users or maximizing the incomes for the energy sales to the grid [4], [5]. Such a control is performed by manipulating the power flows of the energetic resources through inverters in AC microgrids.…”

Types of inverters and topologies for microgrid applications ABSTRACTInverters are the key actuator in the control of AC microgrids, since they manage the power flows of both the generators and energy storage devices. In general, there are three types of inverters depending on the control strategy: grid feeding inverters, grid forming inverters and grid supporting inverters. Those inverters can be implemented with different hardware topologies, each one of them with advantages and disadvantages. This paper presents a synthesis of the inverter topologies widely used in AC microgrids. Moreover, this paper also describes the inverters architectures and main control strategies.

In the recent power system scenario, the concept of microgrid is evolving rapidly. The architecture should be robust enough to cater the complexity of integration of distributed generation sources, demand-side management, and storage. The fast growth of embedded generation with other advanced power electronic interfaces and components along with energy storage devices change the operating pattern of the integrated power system scenario. In this context, protection is the vital aspect for qualitative uninterrupted power and making the system resilient to adverse, and faulty conditions. Many associated issues, particularly related to AC microgrid systems like the large difference in the short-circuit level between integrated and isolated mode of operation, bidirectional power flow, unsynchronized reclosing, the blindness of protection, lack of natural zero-crossing current, and false tripping are needed to be focused. In light of the above factors, it motivates us to survey the previous research works on the existing protection strategies to redesign and present the critical analysis of the predicted protection issues of microgrid protection with upcoming advanced technology and methodology. This article presents a critical review of the issues and protection schemes for the DG integrated AC microgrid extensively. Here, the merits, and demerits of each protection scheme, and visible possibilities for any advancement in protection strategies to enhance the reliability, selectivity, and security of AC microgrid is emphasized keeping in mind the different connections and configurations. In addition, this work also focuses on integrating the intelligent approaches/devices that help to elevate the current protection schemes to be smarter and efficient.
