Economic Dispatch Using Lambda-Iteration Method Without Considering Network Losses - Example 2

In this video, we solve a clear, detailed example of the Economic Dispatch problem—without considering network losses—to help you master the core concepts.

You’ll learn:
1. What Economic Dispatch is and why it’s essential for cost-effective power generation.
2. How the Lambda-Iteration (λ-Iteration) method works to minimize total fuel costs while meeting demand.
3. A complete numerical example – from setting up generator cost functions to iteratively finding the optimal lambda.
4. Hand calculations and logical reasoning behind each iteration, making the process easy to follow and apply.

Perfect for students, power engineers, and anyone preparing for competitive exams like GATE, UPSC, or university tests in power systems operation.

Example features:

Multiple thermal generators with quadratic cost functions.

Step-by-step derivation of incremental cost curves.

Manual iteration process to match total generation with load demand.

Clear tabulation and explanation of results.

By the end of this video, you’ll be confident in solving basic Economic Dispatch problems using the Lambda-Iteration technique—a key skill in power system analysis and operation.
