I'm pleased to share this, a preprint of our first work on predicting electrical grids using graph neural networks: "Enhanced Load Forecasting with GAT-LSTM: Leveraging Grid and Temporal Features" led by Ugochukwu Orji arxiv.org/abs/2502.08376 #ai4good #forecasting #GNN #electricalgrid

arXiv.orgEnhanced Load Forecasting with GAT-LSTM: Leveraging Grid and Temporal FeaturesAccurate power load forecasting is essential for the efficient operation and planning of electrical grids, particularly given the increased variability and complexity introduced by renewable energy sources. This paper introduces GAT-LSTM, a hybrid model that combines Graph Attention Networks (GAT) and Long Short-Term Memory (LSTM) networks. A key innovation of the model is the incorporation of edge attributes, such as line capacities and efficiencies, into the attention mechanism, enabling it to dynamically capture spatial relationships grounded in grid-specific physical and operational constraints. Additionally, by employing an early fusion of spatial graph embeddings and temporal sequence features, the model effectively learns and predicts complex interactions between spatial dependencies and temporal patterns, providing a realistic representation of the dynamics of power grids. Experimental evaluations on the Brazilian Electricity System dataset demonstrate that the GAT-LSTM model significantly outperforms state-of-the-art models, achieving reductions of 21. 8% in MAE, 15. 9% in RMSE and 20. 2% in MAPE. These results underscore the robustness and adaptability of the GAT-LSTM model, establishing it as a powerful tool for applications in grid management and energy planning.

#TIL: #Texas is an island unto itself when it comes to its #ElectricalGrid — except where it isn't.

For example, WECC provides power to the westernmost triangle with two interties operating >75% OTC more than 50% of the time. SPP supplies the 'panhandle' and across the northern half of the state, including 2 DC ties to the Eastern Interconnection. SERC provides service near the border with Louisiana.

And with many new Western #Energy Imbalance Svc ties, #TX's #ERCOT has admitted its failulre.

Next post of my living literature review is out! This month we're diving into #ResilientFood - what could we eat if sunlight disappeared or our #ElectricalGrid collapsed? 🌍
This builds on the work at #ALLFED - Alliance to Feed the Earth in Disasters in general and on a great review by Juan B. García Martínez in particular. I explore how different foods could help sustain humanity during global catastrophes. From #seaweed to #SingleCellProtein, there are many options. The post also examines what we can learn from #OperationWarpSpeed about rapidly scaling critical technologies when we need them most. 🌱🔬

To arrive at their breakthrough, the study researchers combined two prior approaches: the original solution that treated #networks as #traffic; and a later one that instead viewed them as an #ElectricalGrid.

#Biden announces actions to modernize America’s #ElectricalGrid, paving the way for #CleanEnergy and fewer outages edition.cnn.com/2024/05/28/cli #USpol

"There is more #electricity from #SolarPower alone waiting to get on the grid than the entire amount of #energy currently on the grid. To combat the #ClimateCrisis and increase the amount of cheap energy from clean sources like #wind and #solar, the US needs more modern transmission lines."
