“…The control in hybrid AC/DC MGs is more complicated due to the absence of a global variable which can be used for power-sharing, voltage and frequency regulation. Control of the interlinking converter such as per unitized voltage and frequency control on both sides are proposed [80][81][82] and can be further investigated.…”

With the rapid development of power electronics technology, microgrid (MG) concept has been widely accepted in the field of electrical engineering. Due to the advantages of direct current (DC) distribution systems such as reduced losses and easy integration with energy storage resources, DC MGs have drawn increasing attentions nowadays. With the increase of distributed generation, a DC MG consisting of multiple sources is a hot research topic. The challenge in such a multi-source DC MG is to provide voltage support and good power sharing performance. As the control strategy plays an important role in ensuring MG's power quality and efficiency, a comprehensive review of the state-of-art control approaches in DC MGs is necessary. This paper provides an overview of the primary and secondary control methods under the hierarchical control architecture for DC MGs. Specifically, inner loop and droop control approaches in primary control are reviewed. Centralized, distributed, and decentralized approach based secondary control is discussed in details. Key findings and future trends are also presented at last.

“…It is important since various AC and DC components (sources, loads, storages) are often and often connected directly to subgrids and microgrids, primarily to avoid unnecessary power conversion stages and to increase the overall efficiency. Thus, the hybrid AC-DC power architecture implemented in microgrids improves the reliability and power quality of the overall system [18,40,41].…”

Abstract:Energy efficient prosumer microgrids (PMGs) with active and flexible demand side management (DSM) mechanisms are considered to be crucial elements of future smart grids. Due to an increasing share of renewable energy and the growing power demand, appropriate tools to manage not only the loads but also small generation units, heating and cooling systems, storage units and electric vehicles should be provided for them. Therefore, this paper proposes an innovative approach to both physical and logical organization of an active DSM system for future building-integrated prosumer microgrids (BIPMGs), based on standard building automation and control systems (BACS) as well as Internet of Things (IoT) paradigm. New event-triggered control functions with developed universal, logical interfaces for open BACS and IoT network nodes are presented and their implementation in smart metering as well as fully integrated energy management mechanisms is analyzed. Finally, potential energy efficiency improvements with proposed BACS functions are discussed, based on BACS efficiency requirements defined in the EN 15232 standard.

“…It can be of AC micro grid, DC micro grid and Hybrid Micro grid (HMG). Due to the interfacing facility with the conventional utility grid, AC micro grids became popular in the last decade [1]. Since most of the renewable sources have DC interfacing, having DC sub grid becomes mandatory in the micro grid.…”

 Abstract: An efficient Fuzzy Logic Controller (FLC) is proposed for maintaining constant voltage and frequency in a Decoupled DC micro grid system. The micro grid is modeled with solar, wind turbine, Fuel cell, battery and loads. Individual fuzzy MPPT (Maximum Power Point Tracking) controllers have proposed for solar, wind and fuel cell to extract maximum power from the sources and also to maintain constant voltage at DC bus. For the bidirectional power flow among the buses in the micro grid with power management strategy, an efficient Fuzzy logic controller is proposed for the bidirectional converter connected between DC and AC buses. The performance indices such as ITAE, ITSE, and settling time, rise time of DC link voltage has determined and it is being compared with the conventional Proportional Integral (PI) controller to endorse the performance of the proposed FLC. The results prove that the FLC has better performance in all aspects and it is more suitable for the power management in micro grid.
