Suppose a power system consists of two isolated regions: a western region and an eastern region. Five units have been committed to supply 3090 MW as shown below. The two systems are separated by a transmission line that can handle a maximum transfer of 550 MW in either direction. Calculate the spinning reserve for the overall system and for eachregion.
Can you provide clear solution? so i can rate!

I have just started my first Semester (Fall 2021) out of 4 semesters in Master of Applied Science (M.A.S) in Power Engineering at Illinois Institute of Technology. I did not clearly undersand the course enrollment system because I am new to the system, so I ended up enrolling in courses; ECE58-Microgrid Design and Operation, and ECE579-Computer Aided Design of Electrical Machines. It appears ECE582 listed ECE418 (Power System Analysis) as a prerequisite; and ECE539 requires ECE319 (Fundamentals of Power Engineering) and ECE412(Hybrid Electric Vehicle Drives) as prerequisites. Let me hasten to add that I graduated in 2009 in a different academic setup in Africa in Electrical Engineering. So, not only do I have to cover the gap of about 12 year out of classroom, but I have compounded the problem by jumping into advanced courses before enrolling into foundation courses. Unfortunately I can no longer switch courses as the enrollment window has passed. I am only left with one option; to…
