“…In response, the authors in [80] proposed unique optimization techniques such as the lightning search algorithm (LSA) to minimize DER operating costs while optimizing ESSs. Similarly, hybrid control methods combining advanced algorithms were explored in [158] for the energy management of interconnected renewable energy sources. Social and economic factors have also been considered in other research works, with frameworks aiming to reduce overall running costs while enhancing customer benefits.…”

The deployment of isolated microgrids has witnessed exponential growth globally, especially in the light of prevailing challenges faced by many larger power grids. However, these isolated microgrids remain separate entities, thus limiting their potential to significantly impact and improve the stability, efficiency, and reliability of the broader electrical power system. Thus, to address this gap, the concept of interconnected smart transactive microgrids (ISTMGs) has arisen, facilitating the interconnection of these isolated microgrids, each with its unique attributes aimed at enhancing the performance of the broader power grid system. Furthermore, ISTMGs are expected to create more robust and resilient energy networks that enable innovative and efficient mechanisms for energy trading and sharing between individual microgrids and the centralized power grid. This paradigm shift has sparked a surge in research aimed at developing effective ISTMG networks and mechanisms. Thus, in this paper, we present a review of the current state-of-the-art in ISTMGs with a focus on energy trading, energy management systems (EMS), and optimization techniques for effective energy management in ISTMGs. We discuss various types of trading, architectures, platforms, and stakeholders involved in ISTMGs. We proceed to elucidate the suitable applications of EMS within such ISTMG frameworks, emphasizing its utility in various domains. This includes an examination of optimization tools and methodologies for deploying EMS in ISTMGs. Subsequently, we conduct an analysis of current techniques and their constraints, and delineate prospects for future research to advance the establishment and utilization of ISTMGs.

“…Van den Broeck et al [38] evaluated the power conversion efficiency of a three-level buck DC-DC converter when operating in unbalanced bipolar DC microgrids. A modelling and design topology for a bidirectional DC-DC converter was developed which improved the efficiency of the converter, enabled efficient usage of renewable energy sources, and reduced the switching losses [39]. Rai et al [40] proposed the use of converter arrays in place of centralized converters to improve the converter efficiency in a DC microgrid.…”

“…Diode rectifiers have the highest efficiency because they have no switching losses or power losses in their gate driver circuits. The second method involves solving the problems using software algorithms, i.e., by considering the converter efficiency in energy management algorithms, and an appropriate energy management strategy can improve the performance of a microgrid by compensating for the power of the converter [39,[41][42][43][44][45][46]. With the aim of promoting the transmission efficiency of the converters, a deep reinforcement learning optimization scheme with a triple-phase shift was proposed [41].…”

This paper presents a supervisory system that considers converter efficiency for local microgrids of commercial buildings to solve the uncertainty problem of the sources and loads while also optimizing local microgrid operating costs and maintaining power supply quality for commercial buildings. The supervisory system includes an energy management layer and a power management layer. In the energy management layer, a long-term optimization approach is used to reduce the operating costs by considering the dynamic converter efficiency. In the power management layer, a real-time power optimization method is structured to deal with the uncertainty problem of the sources and loads, and to ensure that the direct current bus power is balanced while also guaranteeing the power quality by considering the dynamic converter efficiency. Four cases are proposed for the supervisory system, and these cases are simulated in MATLAB/Simulink under three typical weather conditions: cloud, sunshine, and rain. The comparison of simulation results for cases 1 and 2 illustrates the impact of converter efficiency on energy coordination in microgrids. The simulation results of cases 3 and 4 verify that the performance—in terms of the power supply quality and the operating costs—of the proposed microgrid supervisory system considering dynamic converter efficiency outperforms that of the microgrid supervisory system considering fixed converter efficiency.

“…A PID controller strategy that takes into account Internal Model Control (IMC) adjustments was designed so that the DC motor could run reliably. Using a process model to build the PID controller parameter for optimal setpoint tracking and load disturbance rejection [ [14], [15]], [16] is the goal of an IMC method. To get the necessary speed overrun, a filter can be connected to the drive input.…”

Throughout the manufacturing process of a car, the safety of pedestrians is frequently put in a secondary position to that of the occupants of the vehicle, despite the fact that both are extremely important. The findings of this study will perhaps shed some light on the problem of pedestrian safety when they are on the road. The accomplishment of the objective is made possible by conducting research on the safety system that, in the event of the worst-case scenario, applies warning signals and brakes automatically in order to avoid collisions involving vehicles and pedestrians. In this situation, an image-processing-based safety technology is utilised to detect pedestrians and immediately apply the brakes. At first, the camera that has been mounted in the vehicle makes use of an image processing algorithm in order to monitor the obstacles that are in its route. The automobile will automatically apply the brakes if it determines that a human is approaching at a distance that could be considered hazardous. In the event of an unexpected emergency, such as when pedestrians unexpectedly cross the path of the automobile, the controller will deploy the airbag by employing a servo motor to pull it out from behind the engine cover. Using this strategy, we may ensure the safety of pedestrians by lowering the number of accidents that occur, all without changing the kinds of cars that are driven or driven by. A functional prototype of the suggested improvements is currently available for evaluation.
