Multi-Objective Transmission Expansion: An Offshore Wind Power Integration Case Study

no code implementations16 Nov 2023 Saroj Khanal, Christoph Graf, Zhirui Liang, Yury Dvorkin, Burçin Ünel

Our results indicate that accounting for negative externalities necessitates greater upfront investment in clean generation and storage (balanced by lower expected operational costs).

Weather-Driven Flexibility Reserve Procurement: A NYISO Offshore Wind Power Case Study

no code implementations1 Sep 2022 Zhirui Liang, Robert Mieth, Yury Dvorkin, Miguel A. Ortega-Vazquez

To address this, probability- and risk-based reserve sizing models have been proposed, which use probabilistic VRES power forecasts that mostly rely on historical forecast and actual VRES power data for model training.

Operation-Adversarial Scenario Generation

no code implementations5 Oct 2021 Zhirui Liang, Robert Mieth, Yury Dvorkin

This paper proposes a modified conditional generative adversarial network (cGAN) model to generate net load scenarios for power systems that are statistically credible, conditioned by given labels (e. g., seasons), and, at the same time, "stressful" to the system operations and dispatch decisions.

Inertia Pricing in Stochastic Electricity Markets

no code implementations8 Jul 2021 Zhirui Liang, Robert Mieth, Yury Dvorkin

Maintaining the stability of renewable-dominant power systems requires the procurement of virtual inertia services from non-synchronous resources (e. g., batteries, wind turbines) in addition to inertia traditionally provided by synchronous resources (e. g., thermal generators).
