Part 2 Economic Scheduling of Plant Outputs For achieving economical operation, we shall study first the most economic distribution of the output of a plant between the generator, or units, within the plant. Since system generation is often expanded by adding units to existing plants, the various units within a plant usually have different characteristics. The method that will be developed is also applicable to economic scheduling of plant outputs for a given loading of the system without considering of transmission losses. We shall proceed to develop a method of expressing transmission loss as a function of the outputs of the various plants. Then we shall determine how the outputs of each of the plants of a system is scheduled to achieve minimum cost of power delivered to the load.

Third and Fourth Year
• In third and fourth year, the laboratory studies require substantial engineering analysis and design
– A few students are simply unable to make this transition – Critical thinking skills are essential

• A single application of a fundamental law of circuit analysis may result in the desired solution.

Introduction
• After the overall approach has been determined, consider each branch involved in your method independently before tying them together in series-parallel combinations.
– Redraw the nees to combine obvious series and parallel elements,
• which will reduce the network to one that clearly reveals the fundamental structure of the system.

16.3 – Ladder Networks
Here we will calculate the total resistance and resulting source current, and then work back through the ladder until the desired current, I6 , (or voltage) is obtained.
