Linearized power flow models are of great interest in power system studies such as contingency analyses and reliability assessments, especially for large-scale systems. One of the most popular models—the classical DC power flow model—is widely used and praised for its state independence, robustness, and computational efficiency. Despite its advantages, however, the DC power flow model fails to consider...
Flexible ramping products, which are bid-based products recently proposed in CAISO and MISO markets, are designed to provide transparent economic incentives for flexible resources in case of the increasingly high penetration of renewables. In order to evaluate the impacts of flexible ramping products on the market equilibrium, a multi-period Nash-Cournot equilibrium model is established and the potential-function...
The generation mix is continuously varying all over the world and the electricity market equilibrium analysis in this new conditions is vital to the market designer, regulator, operator and participants. Therefore, this paper thoroughly investigates the impact of the changing generation mix on the market equilibrium based on the Cournot competition model. In order to improve the computation efficiency,...
Equilibrium analysis of electricity market is of great importance not only for market operator and regulator to investigate the market power and other relevant issues, but also vital for market participants to determine the bidding strategies to maximize their own profits. Among different equilibrium models, Cournot model is widely used due to its explicit economic meaning and relatively high computation...
This paper presents a novel decentralized mode of Multi-Area Security Constraint Economic Dispatch(MSCED). In fact, there are the power flow limits of tie-lines, the majority of local units satisfy their local load, and only a few units participate in the inter-regional power balance. Based on such reasons, original MSCED can be decomposed into several independent subproblems, for sub area dispatch...
