Summary: Hydro power inflow, wind power, solar power, and electricity demand in Norway were estimated based on meteorological data. The study found that wind power production has a higher correlation with electricity demand compared to hydro inflow and solar power. Hydro power inflow showed a significant increasing trend, while wind and solar power production were less affected by climate differences. Electricity consumption decreased slightly over the 60-year period, resulting in a significant increasing trend in long-term estimated electricity surplus. Additional available electricity is needed to maintain supply security.

Summary: The impacts of climate change, such as water scarcity and increased air temperature, pose significant challenges for the development of the electricity supply system, particularly in countries like Iran. This study used an econometric approach to project electricity demand in Iran across four sectors, considering the impact of changing air temperature. It also investigated the effects of water scarcity on the optimal expansion of the power system, modeling each power plant unit separately using a bottom-up energy system optimization modeling platform called TIMES. The results indicate that fuel price increases significantly affect capacity and cooling technology choices, with renewables becoming more attractive in scenarios with high fuel and water prices and carbon taxes.

Summary: Predicting electricity demand is crucial for energy security. However, the low-carbon energy transition has made previous forecasting methods no longer applicable due to the bidirectional feedback between power demand and generation mix. This study combines the system dynamics model and power generation mix planning model to create a hybrid forecasting method that has smaller prediction error and can predict the collaborative evolution of electricity demand, power generation mix, and carbon emissions. Additionally, the study uses the PGMP model to modify the state transition matrix of the Markov chain, allowing for the prediction of future power generation mix and stable electricity supply.

Summary: Rising global temperatures in the Arabian Peninsula region have led to increased demand for air conditioning, resulting in higher electricity consumption and CO2 emissions. This study focuses on Qatar as a representative country to understand the impact of future regional warming on electricity demand and CO2 emissions. The findings indicate that temperature has a relatively small effect compared to socioeconomic factors, but warming alone could increase electricity demand by 5-35% and CO2 emissions by 20-35% by the end of the century.

Summary: Due to concerns about air pollution, global warming, and the limitations of fossil fuels, renewable energy sources such as photovoltaic applications are being widely integrated into power generation systems worldwide. This study proposes a new switched-capacitor-based transformer-less grid-tied inverter, which utilizes a series-parallel switching technique to achieve voltage boosting capability and implements a common ground technique for high overall efficiency and leakage current elimination. The inverter provides multi-level output voltage, reducing total harmonic distortion of the injected grid current, and incorporates a control strategy for controlling both active and reactive powers. A laboratory prototype of the proposed inverter is assembled and experimental results are analyzed to evaluate its performance.

Summary: This article proposes an event-triggered sliding mode control (ETSMC)-based fault ride-through (FRT) strategy for doubly-fed-induction-generator (DFIG)-based wind turbines. The aim is to regulate the stator terminal voltage by injecting appropriate voltage to regulate it near the reference point. The proposed approach reduces computational burden, chattering phenomena, harmonic distortion, and utilizes a cost-effective DVR topology with a high-frequency isolation transformer. The effectiveness of the proposed approach is validated with a DFIG-based wind turbine connected to a test microgrid.

Summary: This paper proposes a decentralised control strategy using droop-based control to vary the charging rates of electric vehicles (EVs) in real-time in response to nodal voltages, voltage unbalance and the state-of-charge (SOC). The strategy aims to mitigate excessive voltage rise and voltage unbalance in a low-voltage distribution network caused by rooftop solar photovoltaic (PV) systems and unbalanced loads. It achieves this by coordinating the control of EV chargers based on reference voltages calculated according to the location and local conditions of each charger, without the need for a common communication channel or a centralised controller.

Summary: In many countries, grid-following inverter-based power generation systems (IBPGSs) have replaced synchronous generators (SGs) in load sharing in power grids. However, the increased use of IBPGSs can result in decreased system inertia, leading to instability and failures in grid-following IBPGSs. To maintain stability, a grid-forming IBPGS is required that can mimic SGs. This paper designs a grid-forming controller for IBPGSs and compares its performance with SGs during steady-state and transient conditions.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
