Decentralized Coordinated State Estimation in Integrated Transmission and Distribution Systems

no code implementations8 Nov 2021 Ying Zhang, Yanbo Chen, Jianhui Wang, Yue Meng, Tianqiao Zhao

Current transmission and distribution system states are mostly unobservable to each other, and state estimation is separately conducted in the two systems owing to the differences in network structures and analytical models.

Adaptive Load Shedding for Grid Emergency Control via Deep Reinforcement Learning

no code implementations25 Feb 2021 Ying Zhang, Meng Yue, Jianhui Wang

Emergency control, typically such as under-voltage load shedding (UVLS), is broadly used to grapple with low voltage and voltage instability issues in practical power systems under contingencies.

Evaluating Load Models and Their Impacts on Power Transfer Limits

no code implementations7 Aug 2020 Xinan Wang, Yishen Wang, Di Shi, Jianhui Wang, Siqi Wang, Ruisheng Diao, Zhiwei Wang

Since the load dynamics have substantial impacts on power system transient stability, load models are one critical factor that affects the power transfer limits.

Two-stage WECC Composite Load Modeling: A Double Deep Q-Learning Networks Approach

no code implementations8 Nov 2019 Xinan Wang, Yishen Wang, Di Shi, Jianhui Wang, Zhiwei Wang

However, a detailed WECC CLM model typically has a high degree of complexity, with over one hundred parameters, and no systematic approach to identifying and calibrating these parameters.

Deep Generative Graph Distribution Learning for Synthetic Power Grids

no code implementations17 Jan 2019 Mahdi Khodayar, Jianhui Wang, Zhaoyu Wang

Power system studies require the topological structures of real-world power networks; however, such data is confidential due to important security concerns.

Energy Disaggregation via Deep Temporal Dictionary Learning

no code implementations10 Sep 2018 Mahdi Khodayar, Jianhui Wang, Zhaoyu Wang

The electricity signal of each device is then modeled by a linear combination of such patterns with sparse coefficients that determine the contribution of each device in the total electricity.

A Multi-model Combination Approach for Probabilistic Wind Power Forecasting

no code implementations13 Feb 2017 You Lin, Ming Yang, Can Wan, Jianhui Wang, Yonghua Song

Therefore, a novel multi-model combination (MMC) approach for short-term probabilistic wind generation forecasting is proposed in this paper to exploit the advantages of different forecasting models.
