“…In Figure 3, the variables 𝑒; Δ𝑒; 𝐸 and Δ𝐸 show the error rate, error derivative, normalized error and normalized error derivative, respectively. Parameters κ ,κ and 𝑎 are input and output scaling factors and have important effect on the dynamic behavior of the system and can be selected based on experience, by trial and error in simulations, or using advanced meta-heuristic approaches [3]. In Table 2, the fuzzy linguistic variables NB, N, Z, P and PB signify large negative, negative, zero, positive and large positive, respectively.…”

“…The ability to aggregate and integrate renewable resources with microgridbased networks has reduced greenhouse gas production and thus condensed pollution [2]. The capability to produce energy on-site with the consumer has led to the reduction of transmission losses and the elimination of sufferers caused by centralized production, the skill to manage production and consumption in the microgrid structure has reduced investment costs to provide suitable power for new plants, and of course, decreasing power prices and reducing peak power requirements, the skill to work independently or connected to the main macrogrid network, increasing reliability and the ability to deal with cyber-attacks are among the main advantages of microgrid networks [3]. For this purpose, the microgrid networks are the place of many studies in this field.…”

With increasing the penetration rate of microgrids in power networks, their control becomes more and more important, and microgrid frequency control in islanded mode is one of the most important recent approaches which are studied. With the aim of fast microgrid frequency adjustment, this study presents a novel robust approach using fuzzy and reset techniques. Therefore, this paper firstly describes the model of an islanded microgrid consisting of various elements such as renewable resources, variable loads, storage resources and distributed energy resources, and then designs and presents a robust hybrid control technique based on switching. The planned control method consists of three parts, which are: 1-Fuzzy control technique, 2-Fuzzy reset control technique, and 3-Switching between the two techniques. Due to the robust feature of the reset technique, which in addition to quickly reducing the frequency error, it is able to overcome the limitations of linear controllers, and also due to the intelligence of the innovative fuzzy technique, the planned technique is able to quickly remove frequency errors and restore the islanded microgrid frequency in the fastest possible time and with the least ups and downs and fluctuations. As the results of simulation and comparison in MATLAB environment show, the planned technique has a high and undeniable ability to overcome the uncertainty of the model and disturbances on the system even of the most severe type.

Microgrids have been proposed as a solution to the growing deterioration of traditional electrical power systems and the energy transition towards renewable sources. One of the most important aspects of the efficient operation of a microgrid is its topology, that is, how the components are connected. Some papers have studied microgrid topologies; however, these studies do not perform an exhaustive analysis of the types of topologies, their applications, characteristics, or technical advantages and disadvantages. The contribution of this paper is the integration of the most important functional properties of microgrid topologies in terms of reliability, efficiency, structure, costs, and control methods. The study analyzes 21 topologies divided into six classifications with their respective sub-classifications. The analysis was based on the characteristics of the current (AC or DC), the control mechanisms, the transition between the operating modes, and the operating costs. As a result of the evaluation, it was evidenced that SST-based completely isolated coupled AC topologies, completely isolated two-stage AC decoupled, and multiple microgrids show the best performances. In contrast, the use of two-stage and three-stage partially isolated AC decoupled topologies is not recommended because of their high operating cost and low efficiency and reliability.

“…Stability under cyberattacks presents challenges that have not been sufficiently addressed in the literature [65]. For example, synchronization of multiple DERs [66], as well as minimization of stability times, especially during transitions/failures [67], still require further work. Some researchers [68], [69], [70], have demonstrated asymptotical stability of their control architectures using Lyapunov's theory [71].…”
