9_Bus_MATPOWER_GS-FDPF-FNR

This repository contains MATLAB code for performing power flow analysis on electrical networks using different algorithms provided by MATPOWER, a powerful simulation tool widely used in power system engineering.

Overview

Power flow analysis is a fundamental task in electrical engineering, essential for understanding how electrical power is distributed and balanced within a network. This repository offers a flexible and comprehensive solution for power flow analysis, allowing you to explore various algorithms and their impact on system behavior.

I used MATPOWER to solve 9 bus case, methods I used are

• Gauss-Seidel
• Full Newton-Raphson
• Fast Decoupled Power Flow

1. GAUSS SEIDEL METHOD

   

2. NEWTON RAPHSON METHOD

   

3. FAST DECOUPLED METHOD

   

EXPERIMENT AND RESULT

GAUSS SEIDEL METHOD

mpopt = mpoption('pf.alg', 'GS', 'verbose', 3);
runpf('case9', mpopt);

NEWTON RAPHSON METHOD

mpopt = mpoption('pf.alg', 'NR', 'verbose', 3);
runpf('case9', mpopt);

FAST DECOUPLED METHOD

mpopt = mpoption('pf.alg', 'FDXB', 'verbose', 3);
runpf('case9', mpopt);

CONCLUSION

In the contrast, we can see that Gauss – Seidel needs a lot of iteration to get where other two method are, the most efficient method is Fast Decoupled because it can do more iterations than Newton Raphson in less time.
