Special Issue Information

Dear Colleagues,

There is currently a large deployment of smart power grid systems that include various renewable energy sources, such as photovoltaic and wind energy. These renewable energy sources could have considerable impacts on power grid systems from both the technical and environmental sides. The generated renewable energy can cause discontinuity of energy production due to the non-programmable and unpredictable nature of renewable sources. In fact, the output of plants powered by non-programmable renewable energy sources (NPRESs) significantly changes the hourly pattern of zonal loads that need to be met by conventional generation plants. Thus, NPRESs introduce a stochastic component into the electricity demand related to the inherent variability of weather conditions, making the residual electricity load increasingly intermittent and harder to predict. As a result, the high penetration of NPRESs plants results in increasing imbalances between demand and generation and an increasing difficulty in building up the reserve margins needed to manage the randomness of the load, while providing security and stability to the grid. For this reason, there have been increasing efforts by the research community to establish accurate forecasting systems. This Special Issue aims to present advanced forecasting methods with applications that cover various practical challenges in sustainable power grids.

Topics to be covered in this Special Issue include but are not limited to the following:
• Forecasting of PV and wind power generation;
• Energy demand forecasting;
• Forecast models for wind speed and solar radiations;
• Forecast models for grid connected MPPT;
• Electric vehicle load forecasting;
• Electricity price forecasting;
• Forecasting techniques for smart grids;
• Artificial intelligence and data-driven approaches;
• Application of forecasting techniques in power systems;
• Anomalies and faults prediction.

Although the machine-learning model demonstrates high accuracy in wind speed prediction, it struggles to accurately depict the fluctuation range of the predicted values due to the inherent uncertainty in wind speed sequences. To address this limitation and enhance the reliability, we propose an effective wind speed interval prediction model that combines twin support vector regression (TSVR), variational mode decomposition (VMD), and the slime mould algorithm (SMA). In our methodology, the complex wind speed series is decomposed into multiple relatively stable subsequences using the VMD method. The principal component and residual series are then subject to interval prediction using the TSVR model, while the remaining components undergo point prediction. The SMA method is employed to search for optimal parameter combinations. The prediction interval of wind speed is obtained by aggregating the forecasting results of all TSVR models for each subseries. Our proposed model has demonstrated superior performance in various applications. It ensures that the wind speed value falls within the designated interval range while achieving the narrowest prediction interval. For instance, in the spring dataset with 1-period, we obtained a predicted interval with a prediction intervals coverage probability (PICP) value of 0.9791 and prediction interval normalized range width (PINRW) value of 0.0641. This outperforms other comparative models and significantly enhances its practical application value. After adding the residual interval prediction model, the reliability of the prediction interval is significantly improved. As a result, this study presents a novel twin support vector regression model as a valuable approach for multi-step wind speed interval prediction. Full article
