The objective is to evaluate the efficiency and performance of a central control system that prioritizes renewable energy sources and, when necessary, uses a diesel generator and battery as backup power sources. Additionally, MATLAB is utilized to model and simulate the microgrid system. The needs for the microgrid, including the capacities of each energy source and the load demand, are first laid out in the study. In this study, the power production from the PV panels and wind turbines is estimated based on solar radiation and random wind speeds, respectively. The energy output from each source is measured and shown. After that, a centralized control system is established to oversee the operation of the microgrid. The control algorithm ensures that a considerable portion of the load need is satisfied via renewable energy sources. The extra generation that is stored as energy for later use charges the battery. In the case of a load deficit, however, the battery and diesel generator are employed to provide the demand. The battery's energy reserve and charge status are monitored and displayed. The research results, the suggested centralized control system efficiently controls the microgrid operation by maximizing the use of renewable energy sources and reducing dependency on the diesel generator. The findings highlight the need to use effective control techniques to maximize the integration of renewable energy sources.

The fusion of the strengths from both forms of power generation in the CSP-PV hybrid system offers the potential to deliver affordable and manageable solar energy solutions. However, the key parameters of the CSP plant can vary in different situations. Taking these variations into account is crucial for optimizing the overall performance of the CSP-PV hybrid system and ensuring its adaptability to different scenarios. Therefore, there is a need for a method that can optimize all the main parameters of the CSP and the hybrid system at the same time. The maximum acquired energy from the CSP is 7 kWh with meeting the objective of Levelized Cost of Energy (LCOE). In this paper utilized the Flower Pollination Algorithm (FPA). method to globally optimize the CSP-PV Hybrid System. The experimental results prove the effectiveness of this method.

Then the treated water is used to irrigate ornamental trees in the roads, gardens and forests, as well as the residues of the fermentation process are used as organic fertilizer and to improve the quality of agricultural soil. In this research, a hybrid system consisting of a hydroelectric station and an electric generator working on biogas was proposed at the wastewater treatment plant in Gharyan. This is because the city is distinguished by its high location, about 713 m above sea level. The obtained results showed that the proposed hybrid renewable energy system will provide the wastewater treatment plant an electric power of 490 kW, which is sufficient to cover 87.5% of the plant's electrical energy consumption.

However, they are facing limitations in intermittency. This article aims to utilize natural resources integrated with the utility grid and Electric Vehicle (EV) to provide a hybrid system with a minimum of two objectives namely Cost of Electricity (COE) and reliability using the Losses Power Supply Probability (LPSP) method. The two mentioned objectives are considered to satisfy the residential load demand with EV in terms of Vehicle-to-Grid (V2G) as this article considered. The mentioned objective has been addressed by the Improved Antlion Optimization Algorithm (IALO) and coupled with a high supervisory control method called Rule-Based Energy Management Strategy (RB-EMS) to guarantee to spread the power among the system component. Optimization results show the hybrid integration of the utilized RESs with the Battery (BT) gives the most economic and reliable system for the study area integrated with the EV battery. The gained result was validated with a natural-inspired metaheuristic algorithm called Particle Swarm Optimization (PSO). This article assesses the effect on the RESs generators to achieve an economic and reliable system.

Green hydrogen is a promising solution in Libya for converting renewable energy into usable fuel. This paper covers the types of hydrogen, its features, preparation methods, and uses. Green hydrogen production is still limited in the world due to safety requirements because hydrogen has a relatively low ignition temperature and an extensive ignition range and is considered a hazardous element, the lack of infrastructure in Libya, as well as the high cost of production currently. However, the production costs of one megawatt of green hydrogen and fossil fuels are insignificant. This suggests that electricity production from green hydrogen could become an economic competitor to fossil fuels in Libya. This is due to the cost of adding renewable energy to the public electricity grid. Also, the production of gray hydrogen is possible in Libya because of oil through the installation of systems for converting methane gas and capturing carbon dioxide gas.

However, this makes the PQ issue more complicated due to the negative impact of voltage sag on EPG. Unfortunately, the classical P-I controllers fail in eliminating the voltage sag. In this context, this paper, attempts to mitigate the voltage sag in an interconnected PEMFC-EPG system by utilizing advanced equilibrium optimizer (AEO) and particle swarm optimization (PSO) controllers, and their efficiency is demonstrated by comparison with conventional P-I controllers. To achieve this goal, the AEO-PEMFC and PSO-PEMFC are employed in the EPG line with different fault scenarios. The obtained results unveil that both AEO-PEMFC and PSO-PEMFC provide the needed boost of voltage in the single line-to-ground faults (SLGF) scenario by 100.00%. For double line-to-ground faults (DLGF) scenario, a voltage boost of 99.56% and 98.39...

The goal of this research is to shed light on solar energy technologies that may be used to generate clean and sustainable electricity. An energy-economic-environmental study of five Concentration Solar Power (CSP) technologies (parabolic trough, solar dish, linear Fresnel reflector, solar tower, and concentrated PV solar cell) was conducted for 22 selected locations in Libya. The Levelized Cost Of Energy (LCOE) was chosen as a reference for identifying which technology would be most suited for each site. The economic estimates include the cost of environmental damage caused by carbon dioxide gas (CO2) emissions from fossil-fuel-powered power plants. This technique allows clean and renewable energy to compete fairly in the global energy market, even in countries that produce oil and subsidize electricity. ...
