Decentralized control of interlinking converter by interfacing AC and DC micro grids

AC,DC,and hybrid control strategies for smart microgrid application: A review

“…As per the above classifications and related literature survey, 15‐35,48‐58 it is necessary to focus on single‐stage/two‐stage operation, HMG, supervised control strategies, three‐phase MG, and interlink converter‐based MG for future SMG application. In this regard, the associated control strategies have a greater impact on availing an SMG system.…”

“…Looking at the above possible challenges, the power engineers are suggesting different control and design solutions for the enhancement of the MG's performance. A few of the prominent techniques are discussed below 25‐35 Looking at the above problems, for a real‐time application point of view, the HMG system is the most suitable, flexible, efficient, and cost‐effective solution.…”

“…The enhanced networking, innovative design, and reduced switch power electronic‐based HMG structures offer improved PQ and PR of the MG. In addition to that, it reduces the fluctuation of DRE resources, limiting the range and design complexity of synchronous devices, apprehending distributed control, and decreased losses 25,26 In every situation, the selection of HMG systems cannot be a wise decision.…”

Bidirectional Power Flow Control in AC/DC Hybrid System under AC and DC Fault Conditions

“…In dc microgrid, the dc-dc bidirectional converters play an important role in the control of the internal dc bus voltage and in maintaining the system power balance [2]. The use of modern DC loads for their benefits in terms of efficiency, cost and system that can eliminate the dc-ac, ac-dc power conversion stages and their power losses [3].A microgrid is a discrete energy system consisting of distributed energy sources and loads capable of operating in parallel with or independently from the main power grid [4]. In AC or DC microgrids multiple reverse conversions requirement, increases cost and intricacy of the circuit and will reduce the efficiency of the system [5].…”

“…In hybrid AC/DC microgrid system, BIC control can be applied using the droop control scheme for power sharing between AC and DC subgrids [9]. In [3], droop control with frequency and voltage deviation based balancing inputs have been performed, indeed merging them into one droop converter working together with other converters, in order to determine the corresponding reference power. Based on the droop control theory, all controlled converters participate in load sharing following the corresponding droop slope [10].…”
