1 Abstract — This paper presents a potential algorithm for continuation power flow method in voltage stability assessment. Modified continuation power flow method termed as MCBF was developed which solved the solution of bifurcation point at the Q-V curve. The solvability of power flow at the bifurcation point beyond the maximum loadability point of a system was achieved through the implementat...

This paper presents an improved grid voltage control strategy for wind farms with doubly-fed induction generators (DFIGs) connected to distribution networks based on an analysis of the operation limits of DFIG systems. A modified reactive power limit calculation method in different operation states is proposed and a reactive power control strategy during grid voltage dips/rises is further discu...

A novel neuro controller based simple neuro-structure with modified error function is introduced in this paper. This controller consists of two independent controllers, known as the voltage regulator and the angular controller. The voltage regulator is used to modify terminal voltage for the purpose of tracking a reference voltage. The angular controller is utilized to guarantee the stability o...

The modified nodal analysis (MNA) is probably the most widely used formulation for modeling and simulation of electric circuits. Its conventional form uses node potentials currents across inductors voltage sources as unknowns, thus taking an viewpoint. In this paper, we propose alternative magnetic oriented analysis(MONA) circuits, which based on charges capacitors primary degrees freedom, givi...

Distribution systems are the major interface between electricity consumer and electrical transmission system. Requisite amount of planning is necessary for these to be in order as they vast complex. An important concern on operation distribution its voltage stability. Placing Distributed Generation (DGs) system can address concerns a better way. The location rating DGs going have deep impact pr...

Abstract Voltage instability is a serious phenomenon that can occur in power system because of critical or stressed conditions. To prevent voltage collapse caused by such instability, accurate prediction necessary for planning and operation. This paper proposes novel index ( NCPI ) to assess the stability conditions lines. The effectiveness applicability proposed are investigated on IEEE 30-bus...
