If there exists no load curtailment at each BLP, the system is in the marginal state at time t.
The bulk power system well-being structure consists of the three states of healthy, marginal, and at-risk, as shown in Fig. 1 [4, 16, 17, 18] where both healthy and marginal states are considered as the success state (i.e. no loss of load) while the at-risk state is a failure state (i.e. having loss of load).
He is no longer at the point where he can win the nomination just by winning the marginal states, or even the "lean Romney" states like Illinois.
Foreign policy realists sometimes ask how much seemingly marginal states such as Sudan really matter.
Table 2 System well-being indices of island system when TC = TD, considering all generators with non-zero FOR System well-being indices Load at 2492 MW Probability of healthy state (PH) 0.98832 Probability of marginal state (PM) 0.01164 Probability of at-risk state (PR) 0.00004.

Then he lamented the marginal state of the sport.
In particular, California and New York City both have top marginal rates about 6 percentage points higher than the national average of a 7% top marginal state income tax rate.
The probabilities of the healthy, marginal and at-risk states at various load levels are presented by green, yellow and red color, respectively.
The quantitative measures of system well-being are in forms of the probabilities, frequencies and durations of the healthy, marginal and at-risk states.
