With the increasing penetration of renewable energy and inverter-based resources, power systems exhibit stronger uncertainty and nonlinear dynamic characteristics, which increases the need for accurate short-term prediction of dynamic states. This study proposes a hybrid prediction method combining Long Short-Term Memo...
A hybrid FCM-WGM-BiLSTM-Transformer (FW-BTP) framework integrating Fuzzy C-Means clustering, Weighted Grey Model (WGM) trend extraction, and a coupled BiLSTM-Transformer module is proposed, supporting refined scheduling in modern power systems.
Given the challenges associated with renewables-based power grids, such as greater volatility, greater non-stationarity, and traditional forecasting techniques failing to sufficiently adjust to adaptive changes, this paper studies the design and implementation of an adaptive power grid load forecasting model suitable t...

To address the power imbalance risk between renewable energy output and load demand under extreme weather conditions, this paper proposes a pre-control scheme generation method based on the integration of multiple frequency regulation resources and deep reinforcement learning. First, mechanism models for wind power and...
Accurate wind power forecasting is essential for renewable-energy accommodation, low-carbon dispatch, and the sustainable operation of modern power systems. However, wind power series exhibit pronounced non-stationarity, strong volatility, and multi-scale evolution, making long-term trends and short-term disturbances d...
