Integer modelling of spinning reserve requirements in short term scheduling of hydro systems: an application to power trading

This paper investigates the consequences for power system operation, if links are installed between Sweden and thermal dominated power systems. The authors have applied a short term planning method to high, medium and low load scenarios. For each scenario, they calculate the consequences for different combinations of extra power exchange and the provision of spinning reserve. For different cases, they compare the operation cost, the possibility of using the links as intended and the number of start-ups of hydro units
