Voltage Control, By Reactive Power Injection

2. National Technological University of Lima South, Peru

Abstract: The growth of electric power systems due to the increase in demand, generates the need to have a greater number of interconnections between the various generation - load systems, because they allow to serve users with a lower operating cost, attend Sudden load variations, purchase and sale of energy, but these increases, cause a decrease in the margins of chargeability and decrease in the voltage levels in the bars of a power system, resulting in the risk of bringing the system to Tension instability. These decreases can also be produced by the limited injection of reactive power, lack of use of compensation elements, etc. An important aspect of the stability of tension is that it is a non-linear phenomenon, which is why computational methods and tools are used to control the tension in the bars, by means of the injection of reactive power. Therefore, a computational tool that expands the Jacobian matrix will be implemented in order to increase a new state variable, within the Jacobian matrix, which helps to improve tension levels in the face of increased demand
