Forward-Backward Sweep Algorithm for Three-Phase Unbalanced Power Flow in IEEE 33-Bus System (PQ Nodes Only)

MATLAB implementation of forward-backward sweep algorithm for three-phase unbalanced power flow in IEEE 33-bus system containing only PQ nodes. This ready-to-run code provides immediate results and serves as a modifiable foundation for further development and customization.

MATLAB Program Based on Newton-Raphson Algorithm for Power Flow Calculation

This MATLAB program implements the Newton-Raphson algorithm to calculate power flow in electrical networks with known admittance matrix, PQ nodes, PV nodes, and slack bus (UA). Key variables include: U - bus voltages at all nodes, S - injected power at all nodes, S_net - total network losses, PQ_P - calculated active power injection at PQ nodes, PQ_Q - calculated reactive power injection at PQ nodes, delt_PQ_P - active power correction values at PQ nodes, delt_PQ_Q - reactive power correction values at PQ nodes, delt_UA_P - active power correction values at slack bus, delt_U_2 - voltage squared correction values at slack bus, delt_PQV -
