PSASP Power Grid Voltage Static Stability Analysis Method -Determine the System Key Node and the Region

In recent years, with the growth of the power grid power load, the power system voltage static stability problems gradually appear,The study found that, often from the system voltage stability the weakest node set off, and gradually into the surrounding weak (nodes) regional spread. How to determine the system key nodes and area is PSASP voltage static stability analysis method, from the essence of voltage stability and principle, to calculate the power of each node Leading voltage instability mode participation factors to determine the size of voltage stability judgment the weakest node or area.

The Stability

<p>The main objective of this research work is to analysis the voltage stability of the power system network and its improvement in the network.voltage stability of a power system. A system enters a state of voltage instability when a disturbance, increase in load demand, or change in system condition causes a progressive and an uncontrollable drop in voltage or voltage collapse. The continuing increase in demand for electric power has resulted in an increasingly complex, interconnected system, forced to operate closer to the limits of the stability. This has necessitated the implementation of techniques for analyzing and detecting voltage collapse in bus bar or lines prior to its occurrence. Simple Newton Raphson algorithm based voltage stability analysis has been carried out. Matlab based simulations for all the factors that causes voltage instability has been implemented and analyzed for an IEEE 30 bus system. The proposed model is able to identify the behavior of the power systems, network under various voltage stability conditions and its possibility of recovery/stability improvement of the power system network has been discussed.</p>
