“…A perturbation of the load on the demand side with a magnitude of 0.1 p.u at t = 1 s is applied to the closed-loop system, while the simulation length considered to be 50 s (t sim = 50 s). Considering that time to the power of four (t 4 ) is used as a factor in the OC, applying perturbation in the time interval of 0-1 s may release the controller for large initial deviations. To model the FO operators, the FOMCON plugin is used in MATLAB [41], where the frequency range of the operators is set in the range of [0.001, 10000] and the approximation order is equal to 5.…”

“…Traditional ESSs, according to the literature, are typically not a favour alternative for performing the LFC activities because of their limited life and capacity. Demand side management techniques have demonstrated strong performance in providing frequency stability of μGs, in addition to its effectiveness in scheduling and management duties [4, 5]. The adjustable loads, particularly those that can be adjusted or rapidly switched on and off, has shown positive outcomes in the μGs’ frequency control loops.…”

Modern electrical power system design will increase renewable energy sources (RES) dominance. Rotating masses, the main source of inertia in power systems, have been greatly decreased in renewable energy producing systems. Thus, load–frequency equilibrium is an important indicator of these systems' performance and safety. This work introduces a fractional‐order (FO) operator‐based cascade control structure for islanded microgrid (μG) load‐frequency control (LFC). The structure utilizes a tilt–FO derivative with filter (TFODn) in the first level to reduce noise. The second level implements the proportional integral (PI) controller's FO form (FOPI), making it a tilt–FO derivative with a filter cascaded to the FOPI controller (TOFDn‐FOPI). The optimal controller parameters for quick dynamic responses with low frequency fluctuation are determined using a unique cost function and prairie dog optimization (PDO) algorithm. The LFC control loops have frequency deviation‐based responsive loads (RL). Control signal delays, RES output changes, parameter uncertainties, and cyber vandalism are examined. Laboratory‐scale tests also assessed the controller's practicality. The proposed controller outperforms standard and FO type proportional integral derivative (PID) and PD‐PI controllers. The TFODn‐FOPI controller is suitable for complicated closed‐loop systems like islanded μGs due to its faster error clearing, reduced RL capacity, and superior time and frequency domain indicators.

“…The management of MMGDN with the approach of optimal exploitation of the common coupling point of MGs has been studied in Reference 20. In Reference 9, the effects of DRPs on the changes in operating and management costs of DNs consisting of several MGs have been studied from the perspective of technical and economic indicators. The scheduling and operation of multicarrier systems that include energy hubs with diverse types of power sources, using the Cournot competitive game strategy and taking into account the DRP and the ESSs, is of the recent studies in the area of energy systems management 21 .…”

This study investigates a hierarchical approach for modeling the mutual impacts of distribution network (DN) decisions and microgrids in a multi‐microgrid system under the cover of a two‐level problem. Due to the conflicting interests of decision‐makers in an active DN, the optimization problem has a hierarchical structure, with distribution companies (Discos) at the top attempting to maximize profits and microgrids at the bottom attempting to reduce costs. This study examines the relationship between the unpredictability of renewable energy sources and power demand. In this mechanism, the influence of the demand response program (DRP) is also considered an important aspect of intelligent systems. The two‐level nonlinear optimization problem has been transformed to a one‐level linear problem using dual theory and KKT conditions. According to the findings of the studies, even though cost reduction is the sole objective of scheduling in centralized mode, applying DRP to the system results in a 16% reduction in overall costs for the two‐level scheduling method, and a 22% reduction in daily costs when compared to two‐level scheduling without DRP.

The electricity sector is witnessing a rise in renewable energy sources and the widespread adoption of electric vehicles, posing new challenges for distribution system. Additionally, the surge in carbon emissions resulting from industrialization and population growth continues to worsen global warming and climate change. In response, integrating electric vehicles (EVs) and battery energy storage systems (BESS) has emerged as a critical strategy, presenting both challenges and opportunities in effective energy management. BESSs offer potential solutions to mitigate these impacts. Furthermore, this review thoroughly explores issues related to lithium‐ion batteries, particularly in the context of EVs and energy management systems (EMS), identifies challenges, and provides recommendations for future research directions.
