Common use of Table 2 Clause in Contracts

Table 2. Minutes per year with the corresponding probability and the inverse cumulative probability as a function of standard deviation. In the third step, the value rqh, which represents the same range for an allowed normal distribution of the quarter-hourly average frequency deviation, is calculated based on the assumption that the two signals are not correlated: In the fourth step, the ranges which correspond to the probabilities required by SO GL Article 128(3) are calculated taking rqh as basis. The probabilities are calculated as follows: For the calculation of the ranges, the inverse cumulative probabilities of and will be used. SO GL Parameters qh per year Probability inverse cumulative probability value as c σ qh outside level 1 ACE range 5256 0.85 1.0364 σ qh outside level 2 ACE range 876 0.975 1.96 σ Table 3: Values outside the ranges. In the last step, the level 1 and level 2 ranges (L1 and L2) are calculated for each LFC BLOCK. With KSA as K-Factor of the Synchronous Area expressed in MW/Hz, KFCR as the total FCR of the Synchronous Area and KFCR,i as initial FCR obligation of LFC BLOCK i, the targets are given by:
