Traditional methods relying on manual expertise and existing data-driven models often inadequately capture intricate multi-source temporal features. To address these limitations, this paper proposes a novel contrastive learning-based model for wireless link quality assessment in smart grids. Our framework employs Link Quality Indicator (LQI), Received Signal Strength Indicator (RSSI), and Signal-to-Noise Ratio (SNR) as multi-view inputs. A cross-view semantic alignment strategy is introduced to extract noise-robust shared features across these heterogeneous indicators. Furthermore, we design a hybrid attention temporal encoder integrating Long Short-Term Memory (LSTM) networks, adaptive channel attention, and global temporal attention modules. This cascaded architecture achieves deep fusion of local dynamic feature enhancement and global long-range dependency modeling. Experimental validation on 48 hours of continuously collected real-world communication link data demonstrates that the proposed model outperforms baseline methods, achieving accuracy improvements of 2.5% to 7.7% with validated statistical significance. Specifically, for abnormal link states, the model maintains a high recall rate of over 92.1%, ensuring reliable fault detection. While maintaining high overall stability, we observe minor performance degradation under conditions of extreme burst noise or high rates of missing data. Crucially, it exhibits substantially enhanced robustness and generalization capability, particularly in identifying abnormal link states under challenging EMI conditions.</p></div>","PeriodicalId":538,"journal":{"name":"Energy Informatics","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s42162-026-00622-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146027113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing methods still have limitations in handling complex nonlinear relationships in photovoltaic temporal data. To tackle this, this paper proposes a new model combining Long Short-Term Memory (LSTM), Differential Transformer (DiffTransformer), and Multi-Objective Escape Algorithm (MOESC) for short-term photovoltaic power prediction optimization: Preprocessed data is input into the LSTM-Differential Transformer model, with the Differential Transformer encoder capturing fine-grained temporal changes via optimized multi-head attention and rotary positional encoding, and the LSTM decoder integrating local temporal information for power prediction. Subsequently, Pareto-improved MOESC performs multi-objective optimization on the model’s key parameters (balancing <i>RMSE</i>, <i>MAE</i>, and <i>R²</i>), with the optimal parameters selected from the Pareto frontier. Experiments based on the Guoneng Rixin photovoltaic dataset show that, with user-defined weights (<i>RMSE</i>: 30%, <i>MAE</i>: 30%, <i>R²</i>: 40%), this method outperforms XGBoost, LightGBM, SVR, LSTM, GRU and the unoptimized LSTM-Differential Transformer model in photovoltaic power prediction.

This study conducts a systematic review, following PRISMA guidelines, to synthesise evidence across four domains: technical integration, environmental impacts, socio-economic implications, and governance considerations. The review examines 113 studies spanning solar, wind, microgrids, storage management, and predictive maintenance. Findings show that while AI can enhance forecasting accuracy and system efficiency, these benefits are highly context-dependent and often derived from simulations rather than field deployments.
