Economic Load Dispatch Considering Transmission Loss Using Lambda Iteration Method.

This submission provides a MATLAB implementation of the Economic Load Dispatch (ELD) problem considering transmission losses using the Lambda Iteration Method.

The key features of this code include:

• Input-based demand and initial lambda value.
• Cost function coefficients (constant, beta, and gamma) for three generators.
• Incorporates individual transmission loss coefficients for each generator.
• Iterative solution until power mismatch is minimized.
• Plots of lambda convergence and generator output per iteration.

💡 Highlights:

• Converges to an optimal lambda value.
• Ensures generation meets the demand including losses.
• Generator outputs remain within specified limits.
• Helpful for power systems and energy optimization learners.

🧮 Input Parameters:

• Initial lambda (Lagrange multiplier).
• System load demand (in MW).

📈 Output:

• Power output of each generator.
• Number of iterations to convergence.
• Final lambda value.
• Lambda convergence plot.
• Generator power allocation per iteration.
