1. Assume that the power system is restored to its original configuration. A new plant consuming 20 MW at 0.95 PF lagging is to be added to Bus 4. Will this new load cause any problems for this power system? If this new load will cause problems, what solution could you recommend?
2. Write your own program to solve for the voltages and currents in the power system instead of using program power_flow. You may write the program in any programming language with which you are familiar. How do your answers compare to the ones produced by power_flow?
