The focus on resilience, energy security, and renewable energy is increased. Hence the necessity of autonomous microgrids has become more prevalent. These autonomous microgrids can operate independently and provide stable energy to the users. The design and performance of an autonomous microgrid depends on the control system which will play a significant role in its ability to provide reliable and resilient energy. Hence to account this a hybrid PSO-HHO based optimal control strategy is proposed for power quality improvement. A test case of 3.5 kW PV based autonomous micro grid system is considered and implemented in MATLAB/Simulink. The proposed hybrid PSO-HHO based optimal control strategy is compared with PSO and HHO based optimal control strategies. The performance parameters such as PV maximum voltage PVvmax, PV maximum current PVimax, Voltage RMS VRMS, Current RMS IRMS, PV output power PVop, Autonomous grid power Agp, THD, Efficiency, Inverter Losses Invloss are evaluated in all the cases. The proposed hybrid PSO-HHO based optimal control strategy exhibited the mark improved performance.

“…Recently, a system has been proposed in which consumers have a net balance of zero energy. For this, electrical microgrids are proposed [121][122][123], where together with the loads and generators, energy storage systems are added to make the system self-sufficient and manageable. In many cases, the storage system is replaced by the public electricity grid so that energy is injected into it if it exceeds the microgrid and is absorbed from the grid if necessary.…”

Multiple-output DC–DC converters are essential in a multitude of applications where different DC output voltages are required. The interest and importance of this type of multiport configuration is also reflected in that many electronics manufacturers currently develop integrated solutions. Traditionally, the different output voltages required are obtained by means of a transformer with several windings, which are in addition to providing electrical isolation. However, the current trend in the development of multiple-output DC–DC converters follows general aspects, such as low losses, high-power density, and high efficiency, as well as the development of new architectures and control strategies. Certainly, simple structures with a reduced number of components and power switches will be one of the new trends, especially to reduce the size. In this sense, the incorporation of devices with a Wide Band Gap (WBG), particularly Gallium Nitride (GaN) and Silicon Carbide (SiC), will establish future trends, advantages, and disadvantages in the development and applications of multiple-output DC–DC converters. In this paper, we present a review of the most important topics related to multiple-output DC–DC converters based on their main topologies and configurations, applications, solutions, and trends. A wide variety of configurations and topologies of multiple-output DC–DC converters are shown (more than 30), isolated and non-isolated, single and multiple switches, and based on soft and hard switching techniques, which are used in many different applications and solutions.

In order to improve the accuracy of power time series regulation of DC microgrid photovoltaic power generation and its hybrid energy storage system, a set of empirical mode decomposition (EEMD) control strategy based on fuzzy algorithm optimization is proposed in this paper. Through EEMD decomposition of photovoltaic power data, a set of eigenmode component functions is obtained, the EEMD power decomposition method is designed, and the EEMD optimization fuzzy control strategy is established. Finally, the effectiveness and accuracy of the controller are verified by simulation experiments. The results show that compared with the ordinary EEMD power decomposition control method, the proposed method can achieve better control effect under different power fluctuation characteristics, improve the strong randomness and fluctuation of distributed generation fluctuation, and has strong applicability.
