Quantifying the Availability of Synchronized and Non-Synchronized Generating Units When Needed
Yufan Zhang, Feng Zhao
Do synchronized units have higher probabilities of being available when needed than non-synchronized units? Power system operation implicitly relies on the qualitative belief that…
Efficient Unit Commitment Constraint Screening under Uncertainty
Xuan He, Honglin Wen, Yufan Zhang +2
Day-ahead unit commitment (UC) is a fundamental task for power system operators, where generator statuses and power dispatch are determined based on the forecasted nodal net demand…
Risk-Aware Value-Oriented Net Demand Forecasting for Virtual Power Plants
Yufan Zhang, Jiajun Han, Yuanyuan Shi
This paper develops a risk-aware net demand forecasting product for virtual power plants, which helps reduce the risk of high operation costs. At the training phase, a bilevel prog…
Improving Sequential Market Coordination via Value-oriented Renewable Energy Forecasting
Yufan Zhang, Honglin Wen, Yuexin Bian +1
Large penetration of renewable energy sources (RESs) brings huge uncertainty into the electricity markets. The current deterministic clearing approach in the day-ahead (DA) market,…
Deriving Loss Function for Value-oriented Renewable Energy Forecasting
Yufan Zhang, Honglin Wen, Yuexin Bian +1
Renewable energy forecasting is the workhorse for efficient energy dispatch. However, forecasts with small mean squared errors (MSE) may not necessarily lead to low operation costs…
Fast Constraint Screening for Multi-Interval Unit Commitment
Xuan He, Jiayu Tian, Yufan Zhang +2
Power systems Unit Commitment (UC) problem determines the generator commitment schedule and dispatch decisions for power networks based on forecasted electricity demand. However, w…
Toward Value-oriented Renewable Energy Forecasting: An Iterative Learning Approach
Yufan Zhang, Mengshuo Jia, Honglin Wen +2
Energy forecasting is an essential task in power system operations. Operators usually issue forecasts and leverage them to schedule energy dispatch ahead of time. However, forecast…
