Power System Load Flow Calculation Using P-Q Decomposition Method

This program performs power system load flow calculation using the P-Q decomposition method with IEEE-14 standard bus data. In power system analysis, the P-Q decomposition method is a widely adopted approach for load flow calculations. The algorithm separates the power system equations into active power (P) and reactive power (Q) components, representing generators and loads as combinations of active and reactive power to compute node voltages and power flows throughout the system. The implementation utilizes the IEEE-14 standard bus test case, a commonly used benchmark dataset containing 14 nodes with comprehensive generator and load information for each bus. The code structure includes key functions for matrix formation, Jacobian computation, and iterative solving procedures. Specifically, the program constructs the B' and B'' matrices from the network admittance matrix, then performs iterative calculations to solve for voltage angles and magnitudes. Through the combination of the P-Q decomposition algorithm and IEEE-14 test data, this program accurately calculates node voltages and power flows, providing essential references for power system operation and planning. The implementation features convergence checks and handles typical power system components including generators, loads, and transmission lines with appropriate parameter settings.
