Special Issue Information

Dear Colleagues,

Digital transformation is the contemporary direction of the energy and power industry. If society continues to rely solely on the traditional scheduling model based on energy and grid physics, combined with the actual scheduling experience of grid workers, it will be difficult to adapt to the complex and large-scale new power systems. Therefore, it will be essential to develop and research targeted data analysis techniques and advance their application in energy and power systems. Entropy provides an effective foundational theory for the planning, operation, and regulation of digital energy and power systems. Mining the potentially valuable spatiotemporal information in the massive data of the power system will completely change the model and the operational mode of traditional energy and power systems.

This Special Issue aims to provide a research and discussion platform for the application of entropy and its improved theories in the fields of energy and power systems. The scope of submissions includes, but is not limited to:

  1. New energy generation forecasting and load forecasting methods considering entropy theory.
  2. The application of entropy theory in the optimization of integrated energy systems and power systems.
  3. The application of entropy theory in fault diagnosis and analysis of integrated energy systems and power systems.
  4. Consider the application of entropy based comprehensive energy system, power system resilience modeling, and enhancement techniques.
  5. The application of physical statistical theory in stability and transient analysis of power systems.

The fault diagnosis on a transmission line based on the characteristics of the power spectral entropy is proposed in this article. The data preprocessing for the experimental measurement is also introduced using the EEMD. The EEMD is used to preprocess experimental measurements, which are nonlinear and non-stationary fault signals, to overcome the mode mixing. This study focuses on the fault location detection of transmission lines during faults. The proposed method is adopted for different fault types through simulation under the fault point by collecting current and voltage signals at a distance from the fault point. An analysis and comprehensive evaluation of three-phase measured current and voltage signals at distinct fault locations is conducted. The form and position of the fault are distinguished directly and effectively, thereby significantly improving the transmission line efficiency and accuracy of fault diagnosis. Full article

To improve the accuracy of short-term multi-energy load prediction models for integrated energy systems, the historical development law of the multi-energy loads must be considered. Moreover, understanding the complex coupling correlation of the different loads in the multi-energy systems, and accounting for other load-influencing factors such as weather, may further improve the forecasting performance of such models. In this study, a two-stage fuzzy optimization method is proposed for the feature selection and identification of the multi-energy loads. To enrich the information content of the prediction input feature, we introduced a copula correlation feature analysis in the proposed framework, which extracts the complex dynamic coupling correlation of multi-energy loads and applies Akaike information criterion (AIC) to evaluate the adaptability of the different copula models presented. Furthermore, we combined a NARX neural network with Bayesian optimization and an extreme learning machine model optimized using a genetic algorithm (GA) to effectively improve the feature fusion performances of the proposed multi-energy load prediction model. The effectiveness of the proposed short-term prediction model was confirmed by the experimental results obtained using the multi-energy load time-series data of an actual integrated energy system.
