In this study, the stability problems caused by load variations in the IEEE 14 bus system are eliminated by determining the generation level. When new consumption areas (new loads) are added to power systems, the generation-consumption balance is not provided, and it causes instability problems. Therefore, the effect of new loads on the power system should be investigated in the planning stage. The maximum load levels are determined by increasing the load's power step by step. Line loadings, bus voltages and generator powers are considered as the stability criterion. The load value that causes any of these parameters to be outside the specified limits is accepted as the starting point of instability. In order to determine the generation capacity that eliminates the instabilities, the generator powers were increased step by step. The required generation capacity and its location are determined according to the generator power value, where all instabilities are eliminated. Simulation studies are performed in DIgSILENT PowerFactory platform to investigate the effectiveness of the proposed method. Also, Python scripts that interactively operate with DIgSILENT PowerFactory software are used to change the load and generator powers. The obtained results show that the proposed solution scenarios successfully eliminate the voltage stability problems.
