Comparison of Reliability Measures
Suppose the (peak) load is 1,000 MW for one hour (so the load’s energy is 1,000 MWh) and...
Suppose there are two generating units having capacities and Forced Outage Rates (FOR) of:
- C1 = 990 MW with FOR 1 = 0.0 and ...
- C2 = 110 MW with FOR2 = 0. 0003
- \ Installed Capacity = C1 + C2 = 1,100 MW.
Then the reserve margin is 10%, i.e.; the 1,100 MW of installed capacity exceeds the 1,000 MW (peak) load by 100 MW (which is 10% of the load’s 1,000 MW).
