“…Thus, the frequency of the injected voltage does not change with any load change accordingly. This point is considered as a great advantage compared to the conventional droop control schemes, at which both the frequency and magnitude of the injected voltage change with any variation in loads (Huang et al, 2011;Canizares and Palma-Behnke, 2014;Sen and Kumar, 2018). These voltage changes should be corrected at the secondary control level within the droop schemes.…”

“…The suggested operational scheme belongs to the central control category and its output is applied to all inverters at the same time (Huang et al, 2011;Canizares and Palma-Behnke, 2014;Rajesh et al, 2017;Sen and Kumar, 2018). This concept brings some important advantages which are Palma-Behnke (2014), Han et al (2016a), and Sen and Kumar (2018).…”

“…The operational scheme for the microgrid becomes a challenging research topic because it is supposed for this scheme to realize several simultaneous objectives. Therefore, some publications survey/review the types/structures of operational/control schemes employed to operate the microgrid (Huang et al, 2011;Vandoorn et al, 2013;Canizares and Palma-Behnke, 2014;Han et al, 2016a;Rajesh et al, 2017;Sen and Kumar, 2018). The idea presented in this paper focuses on how the voltage harmonics and voltage unbalance are mitigated in addition to stabilizing the voltage at the loads' side with different loading conditions for linear and non-linear loads.…”

Novel Filters Based Operational Scheme for Five-Level Diode-Clamped Inverters in Microgrid

This paper introduces a new operational scheme for several multilevel (five-level diode-clamped) inverters in the microgrid. The presented operational scheme has a central structure (different from the distributed controllers for droop schemes) to alleviate the drawback of the conventional droop control for microgrid operation. The contribution of this paper is focused on the suggested operational scheme, which has two contributory components. The first component is the novel smooth variable structure filters (SVSF), which are formulated to estimate the disturbances of voltage harmonics and voltage unbalance. The second component is an efficient adaptive sliding mode controller to operate these inverters. This proposed operational achieves equal power sharing among working inverters, compensating for voltage unbalance at the point of common coupling (PCC) at loads, and mitigation for voltage harmonics at the PCC. More importantly, the propounded operational scheme efficiently stabilizes voltage with the variation of balanced, unbalanced, and non-linear loads in addition to the seamless transient and steady-state performance for injected power by inverters. The performance of the suggested operational scheme is justified by simulation results.

Summary Islanding detection is an important factor of the microgrid (MG) protection. Since an MG can work in two modes, ie, grid‐connected and stand‐alone/islanded mode, during any abnormality appearing in the upstream grid, the MG must be decoupled at the point of common coupling and made to operate in the islanded mode to sustain the critical loads. Because of this mode switching, it is necessary to change the pick up current settings of the overcurrent relays (OCRs) at the distributed generators (DGs) to accommodate the changes in the current levels. In this paper, a hardcore reconfigurable multifunctional relay is designed, which is used for the islanding detection as well as mode adaptation within the MG. A modular approach is used to implement the design, which is targeted on field‐programmable gate array (FPGA). Hardware description language, Verilog, is used to develop the optimized hardware. The relay has different submodules viz overcurrent, voltage unbalance, and rate of change of frequency (ROCOF) modules, which are controlled by a soft controller using a multiplexer. Hardware‐in‐loop (HIL) verification for various test cases under different power mismatches is performed on the Real Time Digital Simulator (RTDS) with FPGA setup. The results suggest that the proposed hardcore relay have the capability to identify the islanding event within permissible time and subsequently adapt to the mode of operation effectively.

Summary Recent researches in electrical grids and networks fraternity are directed toward the integration of Microgrid (MG) technologies across the consumer's end. Nowadays, conventional power grid networks are obsolete due to its difficulty of control and protection when many numbers of distributed generations are used. MGs thus acts as a viable solution replacing the conventional grid as it provides integrating platform for Microsources, loads, Electrical Energy Storage Devices and Power Electronic Devices at the demand end within a small locality. MGs are capable of operating either in grid connected or autonomous mode of operation during a faulted situation. However, the system's stability, reliability, and operational control is of extreme concern basically during the islanded mode of operation. Regardless of that, very notable real time implementation and commercial use of MGs are yet to be deployed. This research article brings out a comprehensive review of various challenges and issues related to installation of MG, different controllers for power flow control, idea about the protection system, role of MGs in realizing smart grids (SGs), its major shortcomings, and future prospects.
