A Photovoltaic-Thermal-Solar-Collector (PVT) is a technology that combines the benefits of photovoltaic panels (PV) and solar-thermal-collectors. It can enhance the efficiency of PV by reducing its surface temperature while producing hot water. The PVT's photovoltaic, thermal, and combined-photovoltaic-thermal efficiencies with parallel twisted absorber tubes and nanofluids as working fluids have been determined. A total of 11 parallel twisted absorber riser tubes with headers were used. The optimum header tube diameter was 51mm using Computational-Fluid-Dynamics (CFD) simulations. The utilization of twisted tubes significantly improved the photovoltaic, thermal, and combined-photovoltaic-thermal efficiencies, with the combined-photovoltaic-thermal efficiency rising from 61.2% to 84.6% at a mass-flow-rate of 0.04kg/s and solar-irradiance-level of 800W/m 2 . The effect of employing nanofluids on the PVT system was investigated, with nanofluids contributing to even greater gains in combined photovoltaic-thermal efficiency, which increased from 84.6% to 88.2%. These findings provide valuable insights into the design of high-performance fluid-based PVT systems, highlighting the potential of twisted tubes and nanofluids for enhancing system efficiency.

The utilization of renewable energy sources, such as solar and wind power, has gained significant momentum in recent years due to concerns about the environmental impact of traditional fossil fuels and the desire for energy independence. Governments, organizations, and individuals around the world are investing in and implementing renewable energy systems at an increasing rate. One such issue is the uneven power generation in large solar panel farms, where different zones are affected by varying weather and sun irradiance conditions. This results in a disparity in power generation between zones. In order to address this problem, this paper proposes a solution of incorporating small PV panels that will act like a PV detector in each zone, which are affected by the same weather and irradiance conditions and have the same azimuth and tilt angles to estimate the output power of PV panels. The PV detector will be loaded to their maximum capacity using a Power Electronic Controller (PEC) of MPPT algorithms cascaded with a well-designed topology that maintain the MPPT is working at its maximum load in all cases. By comparing the instantaneous power generated and the maximum power that can be delivered by the PV detector to the PEC, the power of the zone can be accurately determined. In addition, to our MATLAB simulation that allow us to implement in real life our theory and being industry applicable with results approximately equal to results shown in MATLAB.

Wind resource assessments are required to identify a specific area capable of producing valuable energy from wind speeds. This paper aims to optimize wind assessment through wind farm siting and layout in Indonesia’s semi-arid region. Wind data collected on Sumba Island over a one-year period was analyzed to assess the area's wind energy potential. Wind Atlas Analysis and Application Programme (WAsP) and Windographer were used to generate a generalized wind climate and resource maps for the area. Wind farm layout and preliminary turbine micro-sitting were completed with various scenarios in mind to achieve the best possible result. Four different scenarios are considered to maximize power output. There are 34 identical wind turbines with a unit capacity of 90 kW in Scenario 1. Scenario 2 includes 20 identical wind turbines with a total capacity of 3000 kW. In Scenario 3, 14 identical wind turbines with 225 kW of unit capacity are used. There are 12 identical wind turbines with a unit capacity of 250 kW in Scenario 4. The results showed that scenario 1 produced the highest total net Annual Energy Production (AEP) of 11,287 MWh/year with a 3.73 % wake loss. The minimum wake loss seemed to be 2.62 % in scenario 4, with a total net AEP of 10,22MWh/year.

Photovoltaic (PV) solar farms are typically resting at nighttime with their entire expensive assets unused, in which the PV-STATCOM can be utilized to provide voltage control during critical system needs on a 24/7 basis. In the nighttime, the entire inverter capacity is utilized for STATCOM operation. This research developed a smart optimized inverter for reactive power compensation in the distributed grid systems, and new optimized controller for current regulation, voltage regulation, reactive power control, and power factor regulation. The PV-STATCOM controller is optimized using the proposed BaPhin algorithm, which will compensate the voltage, current, real, and reactive power in the distribution system.One of the FACTS devices, the static synchronous compensator (STATCOM), controls the voltage-current components and balances the reactive power in the power system. The voltage, current, power factor, reactive power in the grid-connected PV system as well as in the inverter is regulated by the proposed BaPhin optimization algorithm, which optimally adjusts the proportional controller in the regulators. The performance of the proposed method is more effective in the reactive power compensation than the existing methods.

Electricity grids are now focusing on a new idea called "microgrids" (MG). The idea is to produce energy to reduce dependence on variable cost fuels and reduce harmful emissions into the atmosphere. The system under study is made up of a variety of energy sources, including controllable, renewable and non-controllable sources, as well as energy storage options. This combination is skillfully managed to ensure the MG's reliability and transparency in the face of intermittent power generation. Intermittent weather conditions from uncontrolled sources and loads, such as temperature, solar radiation, wind speed, etc., indicate the numerous disturbances to the MG. Due to the active power compensation, these disturbances affect the power quality, especially the frequency. In order to solve this problem, it is highly recommended to intelligently manage the sources that can be controlled in order to reduce the frequency variation. Using a dynamic model that uses a cascade combination of three proportional integral and derivative (PID) as a reliable frequency control under uncertainty, the controllable sources in this study are modified by a hybrid GA-TLBO. An autonomous MG is simulated in MATLAB/Simulink and tested under numerous circumstances to validate the proposed method for generating the given parameters to reduce the frequency variation in various scenarios.
