An operation adequacy control task is decoupled stepwise in terms of event sequences, cascading events, non-preventive control, and preventive dispatch. Based on the minimum cost-performance-ratio principle, the searches are performed from the bottom up to provide suitable operation adequacy of the minimum defense costs and remaining risks. Iterations may be needed to obtain a global quasi-optimum result. The convolution value of power shortage with respect to the probability is used for ranking the different sequences; the optimization is conducted for each sequence in the descending order of the convolution value. Inside a sequence, the individual events are dealt with in the chronological order. If there is a lack of (or an excess of) reserve capacity within a certain grade, the objects for reserve capacity dispatch are selected for upgrading (or downgrading) from the lower (or the higher) grade, and the optimal executing time is also decided. In case of insufficient instantaneous reserve capacity, emergency control and/or corrective control will be compulsorily executed to avoid uncontrollable blackouts.
