ECE 558 - Spring 2021

Power System Reliability

Project 4 - Due 4 Mar 2021

1. 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. Calculate the LOLE for this system for a single daily peak load of 60 MW.
2. 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:
   1. 150 MW
   2. 160 MW
   3. 170 MW
   4. 180 MW
   5. 190 MW
   6. 200 MW
3. For the generating system in the previous problem, calculate the LOLE for the following peak load values, given that another 60 MW thermal unit with a FOR of 0.02 is added to the system:
   1. 200 MW
   2. 210 MW
   3. 220 MW
   4. 230 MW
   5. 240 MW
   6. 250 MW
   7. 260 MW

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!
