A comparison of residual demand models for oligopolistic markets
(2005)
In many pool-based electricity markets two types of generating companies coexist, namely price-taking and leader companies. In this context, the optimal bidding of a leader company, and consequently the market ...

Compensated Load Flow Solutions for Distribution System State Estimation
(MDPI, 2020-06)
State estimation of distribution systems typically relies on measurement sets with very low redundancy levels. In this paper, this fact is exploited by first solving a conventional load flow, using exclusively a critical ...
