“…A controller is designed using the complex root locus method in [259], auxiliary voltage controller for fault ride through (FRT) in [219] for preventing over‐current, and the combination of a feedback output controller with a disturbance observer in [26] are shown to achieve good performance under grid unbalances. An approach proposed in [260] extends the current physical component power theory to four‐wire systems. The simultaneous active and reactive power control is proposed in [261] based on symmetrical components with a flexibility to achieve three objectives.…”

Unbalance or asymmetry in the distribution network is a well-known power quality issue. In the modern active distribution system, with the increasing penetration of renewables, this phenomenon becomes more pronounced. In the context of microgrids (MGs), several works have been proposed for the management and mitigation of the unbalance, for both the sharing of unbalanced load and maintaining the voltage quality in the islanded mode and for the control of distributed generators in the grid-connected mode during unbalanced conditions. This study comprehensively reviews, summarises, and classifies the various strategies of the unbalance mitigation techniques for the islanded and grid-connected modes of operation for threephase MGs and presents the possible challenges and avenues for future investigations on the topic.

“…This work differs from other related surveys in the literature, such as, [22][23][24][25][26][27][28][29][30][31][32][33][34] in being the first meta-analytic review on efficient SG energy management. From the existing literature, it is also conclude that mostly meta-heuristic techniques are used for optimization because of their ability to deal with large and complex scenarios with less execution time.…”

Energy management of the grid connected microgrid (MG) systems with low cost using a novel hybrid algorithm is implemented in this paper. The novel proposed hybrid technique is the combined performance of both the Random Forest (RF) and Coral Reefs Optimization (CRO) algorithm and in this way it is named as RFCRO. Optimum operation of micro-sources for decreasing the electricity production cost by hourly day-ahead and real-time scheduling is the main objective of the paper. The proposed hybrid technique is to manage the power flows between the energy sources and the grid. To achieve this point, demand response and minimum cost of energy are determined. This technique is involved with the mathematical optimization problems that necessitate more than one fitness function to be optimized simultaneously. By using the inputs of MG-like wind turbine, photovoltaic array, battery, and fuel cell with corresponding cost functions, the RF is employed to predict the load demand. CRO clarifies the squirrel in optimizing the configuration of MG based on the load demand. The proposed hybrid technique is implemented in MATLAB/ Simulink working platform and compared with other solution techniques like

“…The accurate detection of the positive sequence component at fundamental frequency is essential to synchronise grid-connected three-phase converters [98]. A centralised control strategy for power sharing in a microgrid with grid-side converters operated in parallel has been proposed in [99], with reduced sensor requirements with respect to previous solutions. In an islanded microgrid that operates under unbalanced conditions, the asymmetric inverter output voltages could affect the droop control strategies.…”

28 June 2018 was the 100th anniversary of the first presentation on symmetrical components made by Charles LeGeyt Fortescue at the 34th Annual Convention of the American Institute of the Electrical Engineers in Atlantic City (NJ, USA). The introduction of the symmetrical component concept was immediately seen as a milestone for electrical system studies, and many applications have been developed during the ensuing years. Today, refined or advanced contributions to conceptual and practical aspects of electrical applications are still being proposed based on the powerful structure of symmetrical components. This paper recalls the most significant steps made in the electrical engineering field after the introduction of the symmetrical component theory, and indicates recent developments concerning the studies on electrical machines, harmonics and interharmonics in different applications, and the operation of power and distribution systems with distributed energy resources.
