This paper presents a comprehensive review and critical comparison of data-driven forecasting methods based on key parameters, including forecasting horizon, input features, geographical location, forecasting accuracy, training/testing period data length, pre-processing techniques, model architecture, activation functions, training algorithms, and the simulation platforms. Special emphasis is placed on data preparation strategies and model optimization techniques that significantly influence forecasting performance and model robustness. The scope is focused on purely data-driven AI and hybrid approaches, excluding physical and statistical models. An exploration of the strengths and weaknesses of these methods underscores the significance of hybrid models, particularly those combining DNN. A key contribution of this study lies in its structured synthesis of performance outcomes from various reported works, methodically arranged by increasing testing data duration.

Thus, to further exploit the flexibility potential and ensure robustness, a two-stage adaptive robust methodology is proposed, based on an innovative architecture for DC micro-energy system. First, to achieve the efficient utilization of energy, dual-condition heat pumps is integrated into the system architecture with seasonal waste heat recovery (WHR) strategy. Second, a novel batch load demand response (DR) model with a differential compensation scheme is proposed, uniquely incorporating users’ fatigue effect and trust process, to incentivize load participation. Finally, a two-stage adaptive robust planning model that accounts for planning flexibility is developed, utilizing gaussian process regression (GPR) to capture key features of forecasted data. Case studies demonstrate that compared to conventional waste heat recovery strategies, carbon emission reductions increased by 79% and investment costs for photovoltaic, gas turbine and energy storage systems were reduced by 9.1%, 14.3% and 8.6%, respectively. And compared to scenarios that omit planning flexibility, the planning costs can be reduced by approximately 0.5% to 4.9%. Through the incorporation of resource and planning flexibility, alongside the refinement of the uncertainty set, the flexibility of the system is unlocked, while the stability and economy of the planning results are guaranteed.</div></div>","PeriodicalId":29780,"journal":{"name":"Renewable Energy Focus","volume":"55 ","pages":"Article 100742"},"PeriodicalIF":4.2,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144687428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed solver employs second-order cone relaxation, further enhanced through a set of relaxation-tightening constraints, along with feasibility-based and optimization-based bound tightening techniques to improve relaxation strength. A salient feature of the solver is the integration of a no-good cut technique, which enables efficient exploration of alternative candidate solutions within the feasible region. As demonstrated by numerical results, this technique is specifically tailored to the G&amp;TEP problem and significantly improves solution quality while reducing the runtime required to achieve global optimality.

This issue is especially important because solar energy is highly variable and depends on weather conditions, which makes it difficult to keep the power grid stable and reliable. Therefore, there is a strong need for accurate tools that can help predict these changes and improve the way the grid is managed. This study addresses these challenges by leveraging AI-based methods that combine climate data analysis and power grid simulations. The analysis relies on key environmental variables: solar irradiation, temperature, and wind speed to predict two critical outputs: power and voltage levels across the network. Among the tested models, Support Vector Regression (SVR) gave the best performance for power prediction. On the IEEE 123-bus Network, SVR achieved an RMSE of 183.07 and an MAE of 169.15, remaining well within the acceptable margin of 400 kW. For voltage prediction, the Long Short-Term Memory (LSTM) model performed best by capturing long-term time dependencies.
