The increasing use of green energy requires precise weather information for effective operation of renewable energy sources. As for weather stations, they give standard meteorological information, which is not quite accurate enough for renewable energy forecasting at a specific site. This paper introduces a new microweather station system to address this issue gap by providing accurate, effective, and location-specific real-time information for estimating the potential of renewable energies. The system incorporated the application of highly innovative sensor technologies as well as an IoT system that allows for accurate tracking of small-scale weather conditions in specific areas; the adoption of cloud computing; and innovation in the use of mobile apps. The suggested solution allows stakeholders to leverage readily available information for defining energy systems development strategies, grid planning, and overall environmental responsibilities. It is obvious that localized weather data is crucial to the effective dispatch of solar, wind, and other renewable energy technologies, with relevance identified in a world that is increasingly trending towards sustainable energy solutions. The results of the live data received are then converted into graphs and line plots. Also, the real-time data is represented in the form of meters for digital values, which provides a user-friendly environment and easy representation of data. ThingSpeak allows users to monitor and analyze live data effectively, ensuring a better understanding and developing strategic planning for the local weather data.

This article introduces an innovative platform for microgrids (MGs) that enables active energy trading both with the main power grid and directly among MGs. By facilitating Peer-to-Peer (P2P) energy trading, the proposed platform ensures mutually beneficial outcomes, particularly in the presence of advanced energy resources such as Battery Energy Storage Systems (BESSs) and Demand Response Programs (DRPs). From the perspective of power systems, P2P energy trading enhances local energy balancing and promotes self-sufficiency within MG networks. Unlike traditional noncooperative game models, where participants act independently, this study adopts a cooperative game approach that aligns with the autonomous and self-interested nature of MGs. Numerical simulations validate the effectiveness of the platform, demonstrating that MGs can engage in energy trading while achieving economic benefits. Fur-thermore, the platform determines optimal pricing and energy trading volumes, ensuring that participants gain measurable eco-nomic advantages in the P2P market. Additionally, technologies such as BESSs and DRPs significantly enhance energy sharing among MGs, thereby improving overall system efficiency and sustainability.

The increasing global energy demand necessitates sustainable energy solutions to mitigate the adverse effects of fossil fuels. Solar energy, harnessed through Photovoltaic (PV) systems, offers a viable alternative, but its variability poses integration challenges with the power grid. This study proposes a hybrid machine learning (ML) model combining Multi-Layer Perceptron Neural Network (MLPNN) for pattern recognition, Decision Tree (DT) for feature selection, and Bayesian Optimization for hyperparameter tuning to improve solar energy output prediction. Using historical meteorological data from a PV system in Canberra, Australia, the model identified solar irradiance as the most influential feature, with temperature, wind speed, and time contributing unique information. Results demonstrate that while the MLPNN achieved superior prediction accuracy, the hybrid model reduced training time by 30 % with a comparable RMSE, MSE, and $\mathbf{R}^{2}$ . These findings highlight a trade-off between accuracy and efficiency, suggesting the hybrid model for real-time applications and the MLPNN for accuracyfocused tasks. This research provides a practical framework for enhancing solar energy prediction systems.
