Congestion analysis and participants´ behaviour in a pool market

In the liberalised environment of modern electricity markets one of the most important tasks of the independent system operator is to carry out a congestion management efficiently. An estimation of the contribution of market participants to the congestion component of nodal prices is presented. Furthermore, a study of the producers´ and consumers´ bid behaviours is also provided. This study is based on a nodal price analysis and the use of distribution factors. Simulation results are presented for the IEEE 14-bus system and also a realistic high voltage network.
