This paper presents a two-layered framework for managing multi-interval economic dispatch with both transmission and ramping constraints in electric energy systems with a large penetration of variable resources. The proposed model is aimed at ensuring that there is sufficient flexibility in the dispatch to manage large net load ramp events while observing the transmission constraints in the power...
This paper studies the impact of introducing look-ahead dispatch on locational marginal prices in real-time electricity markets. Due to the high forecast error and inter-temporal variability of renewable resources (e.g., wind and solar), many system operators are in the process of upgrading their market clearing engine from static economic dispatch-based ones to dynamic look-ahead economic dispatch-based...
The increasing penetration of renewable generation poses a challenge to the power system operator's task of balancing demand with generation due to the increased inter-temporal variability and uncertainty from renewables. Recently major system operators have been testing approaches to managing inter-temporal ramping requirement. In this paper we propose a robust optimization based economic dispatch...
