Empirical Physics‐Based Normal Behavior Modeling of Drive Train Temperatures With High‐Resolution Wind Turbine Operating Data

Wind Energy, EarlyView.
ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

Short‐Term Multi‐Horizon Line Loss Rate Forecasting of a Distribution Network Using Attention‐GCN‐LSTM

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Accurately predicting line loss rates is crucial for effective management in distribution networks, particularly for short‐term multihorizon forecasts ranging from 1 hour to 1 week. In this study, we propose attention‐GCN–LSTM, a novel method that integrates graph convolutional networks (GCN), long short‐term memory (LSTM) and a three‐level ...

A time‐stamp calibration method for smart meter data based on interpolated least squares

Energy Conversion and Economics, EarlyView.
Abstract Temporal asynchrony in smart meter data, caused by clock drift and protocol failures, significantly undermines grid state estimation and fault location. Traditional synchronization methods often rely on costly hardware or real‐time protocols and are ineffective for historical data and legacy devices.

Wind farm maintenance optimisation strategy considering MFTS distance‐based K‐medoids clustering and mixed Weibull model

Energy Conversion and Economics, EarlyView.
Abstract This paper proposes a wind‐resource‐weighted maintenance optimization framework to reduce operation and maintenance (O&M) costs and improve power generation efficiency. Existing clustering methods based on single distance metrics cannot fully capture the multidimensional temporal characteristics of wind‐speed data, while single Weibull models ...
