Abstract: A calculation model for hydro plant peaking capacity under reservoir anti-regulation was
developed on the basis of previous assessment criteria of the peaking capacity to provide a guide for peaking
operation of yearly regulation reservoirs and higher generation benefits under time-of-use (TOU) power
price. In application of this model to the cascade hydro plants on Blackwater River, the peaking capacity of
the Maoergai hydro plant was evaluated in the conditions of implementing an anti-regulation at the Seergu
hydro plant and a second anti-regulation at the Liuping hydro plant. This simulation indicates that the
anti-regulation scheme efficiently improves utilization of water power resource and hydro plant benefits and
the model proves to be reasonable and applicable.
