Comprehensive review on control schemes and stability investigation of hybrid AC-DC microgrid

Review on microgrids design and monitoring approaches for sustainable green energy networks

“…In 43 , the investigators provide an identical design wherein sustainable DPRs supply essential and non-critical home demands via three distribution system. MGs with a solitary bus architecture 34 , such as those depicted in Fig. 1 a,b, are widely deployed because of their suitability for small and intermediate voltage systems.…”

“…Additionally, as such incorporation of the unpredictability of wind power in MGs increases, the adverse effects of power surges in the middle frequency band (0.01 and 1 Hertz) become more pronounced 48 , 49 . Therefore, control mechanisms that have an essential function in the operation of MGs by guaranteeing continuity and dependability need to be developed to mitigate the effects of these connectivity complexities 34 , 50 , 51 . The uncertainty handling strategies can be broken down into eight distinct classes, which are as follows: Incorporating a variety of various forms of sustainable power, all of which will supplement the others to achieve an improved power profile 52 , 53 .…”

“…The system ought to be capable of regulating the flow of reactive power in response to changes in voltage (VQ mode) as well as active power (PQ mode) (please refer to Fig. 3 a,b) 34 , 91 .

Figure 3 DPRs distinctive voltage-reactive-power profile 34 , 91 .

“…The purpose of this research is to present an overview of the development of control methods in MG and to conduct a systematic evaluation of the various strategies for MG control that have been proposed in the published literature. Many publications have covered the numerous MG control techniques in depth 31 – 34 . Several system-of-systems (SoS)-oriented discussions on MG control techniques are found in 35 ; nevertheless, the primary emphasis is on adapting SoS to MGs.…”

Dynamic Interactions between Parallel Grid-Forming Inverters in a Microgrid

“…The generation of electricity from eco-friendly sources is of significant interest worldwide, as there is an increasing integration of renewable energy into the power system [1]. A microgrid is a system that combines distributed renewable energy resources to function either independently as a stand-alone grid or as a single unit connected to the main grid [2,3]. There are various types of microgrids, including AC, DC, or hybrid AC/DC configurations.…”
