Analysis of IEEE 14 bus power flow calculation characteristics based on Newton-Raphson method

The safe and stable operation of the power system plays a vital role in the construction of the smart grid, this paper addresses the future needs of the power system and the algorithm of tidal current calculation, based on the IEEE standard 14-node power system grid, using MATLAB for simulation, using the Newton-Raphson method to calculate the power system nodes, the line parameters, the resulting line reactive power flows from high voltage to low voltage, active power, and analyse the role of PV, PQ, and balance nodes in the power system; analyse the difference between the analytical solution of the Newton-Raphson algorithm and the machine solution, and highlight the superiority of the Newton-Raphson algorithm in the power system tide calculation; by analysing the strong correlation between power and voltage, and the stability of voltage in By analysing the strong correlation between power and voltage, and the important role of voltage stability in power systems, it is proposed that the voltage at the pivot point can be changed and the voltage of the power system can be adjusted using inverse regulation, forward regulation and constant regulation, and the applicability conditions of the three methods are compared. It is of great significance for the safe and stable operation of power systems.
