The objectives of this project are to carry out the load flow study for a power system with at least 10 buses. The detailed steps are as follow:
Step 1: Develop a GS and NR MATLAB programs to solve the load flow of the selected system. The output of GS and NR programs must include the followings: -
(a) Bus voltages, magnitudes and angles
(b) Load MW and MVAR at all buses
(c) Generator MW and MVAR at all buses
(d) Injected MVAR from capacitor banks
(e) Total MW and MVAR losses
(f) List of voltage violations. The normal range of bus voltages is assumed to be 0.95 - 1.05 p.u.
(g) List of generator MVAR violations. Assume that the MVAR of slack generator is unlimited.
Step 2: Run the developed GS and NR load flow programs and compare between their results in terms of the solution quality, number of iterations, CPU time, ...etc.
Step 3: Run the NR load flow program and check for load bus voltage and generator MVAR violations.
Step 4: Suggest a corrective scenario for each violation, if any, and validate it.
Step 5: Repeat steps 4 and 5 for a stressed system with 25% increase in MW and MVAR of all loads.
Step 6: Repeat steps 4 and 5 for a stressed system with 50% increase.
Step 7: Suppose that one line is removed for maintenance. Run the power flow again. Is the operating condition acceptable? If not, assume that you have the following options to correct the situation: -
(a) By placing a capacitor at buses with low voltage to bring the voltage up to 0.95 p.u. Determine the size of the each capacitor bank. Discuss the solution proposed.
(b) By shedding a part of system loads at buses with low voltage. Determine the amount of load you have to shed in order to maintain the bus voltages above 0.95 p.u. Cut the same percentage of MW and MVAR.
In both cases, no violations are accepted. You may have to change in control variables accordingly to satisfy all operating limits.
Step 8: Write a formal report showing the results of all cases considered with detailed explanation of the suggested scenarios.
