Power flow computation algorithm for determining voltage/current values and tracking convergence iterations
Detailed Documentation
Power flow calculation involves solving nonlinear equations to determine nodal voltage magnitudes, phase angles, and branch current distributions within electrical power systems. The computational process typically employs iterative numerical methods such as Newton-Raphson or Gauss-Seidel algorithms to handle system nonlinearity. Key implementation aspects include:
- Formulating power balance equations using admittance matrix Ybus
- Implementing convergence criteria for voltage mismatches
- Tracking iteration counts until solution tolerance is achieved
- Handling PV/PQ bus type differences in calculation logic
The algorithm accounts for multiple system parameters including generator outputs, load demands, transformer tap ratios, and network topology. Power flow computation represents a fundamental power system analysis tool requiring robust numerical methods and precise modeling of electrical network components.
