Resumen:
Voltage constraints in the Spanish electricity market are solved connecting a set of off-line generators. The start up cost internalized in the fixed income term of the generator bid plays a key role in the solution of voltage constraints since the coupled solution of voltage constraints for the 24 hourly scenarios is different from the individual solution of each hourly scenario. This paper presents an optimization approach to obtain the coupled solution of the daily voltage constraints in the Spanish electricity market. The input data of the problem consists of the individual solutions for each hourly scenario and the bus voltage sensitivities with respect to active and reactive injection of non-connected units. The system cost reduction of the proposed approach is illustrated using an actual example of the Spanish electricity market.
Palabras clave: power system dispatch, security assessment, congestion management.
