Selection of the design production of hydroelectric stations when planning the fuel supplies of power interties with a large share of hydropower

Conclusions

• 1. The minimum expenditures in the power intertie of Siberia occur when planning fuel supplies on the basis of a 95% probability of production of the hydrostations; as a consequence of this, it is expedient to take as the standard planning of fuel supplies on the basis of a firm production of hydrostations with a 95% probability (instead of the existing 50%).

• 2. The conclusion obtained for the power intertie of Siberia with a large share of hydrostations having deep carryover reservoirs can be extended as a first approximation also to other power systems with a large share of highly regulated hydropower, but this problem should be solved after conducting investigations analogous to those described above.

• 3. The investigations conducted showed the expediency for the power intertie of Siberia to correct fuel deliveries, which depend on the production of hydrostations, in May and to take this period as the standard for the given region.
