Interval based transmission contingency-constrained unit commitment for integrated energy systems with high renewable penetration

INTERNATIONAL JOURNAL OF ELECTRICAL POWER & ENERGY SYSTEMS, 119.

By: J. Liang n & W. Tang n

author keywords: Contingency-constrained unit commitment; Integrated energy system; Interval optimization; Power-to-gas
TL;DR: A novel interval optimization framework of contingency-constrained unit commitment for integrated energy systems is developed that incorporates the risk preferences of decision makers in the framework to alleviate the conservativeness of solutions. (via Semantic Scholar)

Sequence Generative Adversarial Networks for Wind Power Scenario Generation

IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS, 38(1), 110–118.

By: J. Liang n & W. Tang n

author keywords: Deep learning; generative models; renewable energy integration; scenario generation
TL;DR: A distribution-free approach for wind power scenario generation is proposed, using sequence generative adversarial networks coupled with reinforcement learning, which avoids manual labeling and captures the complex dynamics of the weather. (via Semantic Scholar)
