Power grid expansion, load demand increase, and renewable energy integration all present severe challenges to the operations. As transmission networks become increasingly stressed, research on voltage stability analysis (VSA) has attracted widespread attentions. Voltage instability usually occurs within a short period, which makes it difficult be detected. To assess margin, P-V curve method been widely used for years. However, this approach is only effective when power factor or reactive...

This paper investigates the impact of price-based demand response (DR) programs on available transfer capability (ATC) in deregulated electricity markets.
