Voltage Stability Analysis during Power Network Node Type Conversion
Author:
Abstract: During the analysis of the power network, a node type conversion will occur under certain extreme conditions. This brings the problem of stability of the power system voltage. This article extracts the characteristic equation of the system voltage critical point by establishing a node voltage-branch current to the power network equation. Therefore, the corresponding solution equation group was in the conversion process of the PQ-PV node. Through this equation group, the difference in the difference between the voltage value of the node and the critical point voltage is formed to determine the system stability after the node type conversion is converted. In the process of calculating the voltage critical point, the improved Newton iteration method is used to avoid Jacques bizarre. This method allows calculations to smoothly reach a state of convergence. The simulation calculation shows that the method proposed in this article is correct and effective.
