For the generating system in the previous project, determine the
increase in load carrying capability at the 0.1 day/year risk level due
to the addition of the 60 MW thermal unit (i.e., difference between
problem 2 and problem 3).
A generating system consists of the following units:
1 x 10 MW unit
1 x 20 MW unit
1 x 30 MW unit
1 x 40 MW unit
The 10, 20 and 30 MW units have forced outage rates of 0.08. The 40
MW unit has a full forced outage rate of 0.08 and a 50% derated state
which has a probability of 0.06. The generating system supplies power
to an industrial load. The peak load for a specified 100-day period
is 70 MW. The load-duration curve for this period is a straight line
from the 100% to the 60% load point.
Calculate the energy index of reliability for this system.
Given that the economic order for the generating units is 40,
30, 20, 10, calculate the expected energy provided to the system by
each unit.
A power system contains the following generating capacity:
3 x 40 MW hydro units, FOR = 0.005
1 x 50 MW thermal unit, FOR = 0.02
1 x 60 MW thermal unit, FOR = 0.02
The annual daily peak load variation curve is given by a straight line
from the 100% to the 40% points. Calculate the LOLE for the following
peak load values:
150 MW
160 MW
170 MW
180 MW
190 MW
200 MW

A four-unit hydro plant serves a remote load through two parallel
transmission lines. The four hydro units are connected to a single
step-up transformer which is then connected to the two lines. The
remote load has a daily peak load variation curve which is a straight
line from the 100% to the 60% point. Calculate the annual Loss of
Load Expectation for a forecast peak of 70 MW using the following data.

Deliverables
Main Campus students must submit their assignments on paper at the
beginning of the lecture. In addition, both Internet students and
Main Campus students must submit an electronic copy via SafeAssignment
on the ECE 558 Blackboard site BEFORE the beginning of class.
SafeAssign does not allow multiple files, so you'll need to find a way
to submit a single file, e.g., scanned images (PNG or JPEG) of
handwritten work can be inserted in a Word Document. MATLAB code, if
any, must appear in an appendix so that we can copy and paste your
code into an M-file to test it. MATLAB code must not be scanned; it
must be included as formatted text. See the "Blackboard SafeAssign"
link on the course home page for details on allowed file types.
Please make sure your file is less than 1 MB in size!
