“…Fig. 6 shows the stability index, W c [1,[7][8][9], in each fault point case. W c is an integrated variation of the energy exchanged between the generator rotor and the power system; thus, the lower the value of the parameter, the shorter the convergence time of the swing.…”

“…In the previous paper [1], the results of the simulation analysis of the synchronous generator stability for a single-machine infinite-bus system with PV installed were presented. Through the simulation analysis, we have obtained the fundamental characteristics of the transient stability in the power system with PV installed, and it was concluded that the transient stability becomes better in the cases of the higher penetration PV without LVRT (low-voltage ride-through) capability.…”

Abstract:In the previous paper [1], the transient stability of synchronous generator in power system with high-penetration PV (photovoltaic) was assessed by simulation analysis of a single-machine infinite-bus system model. Through the simulation analysis, we have obtained some conclusions in terms of the impact of high-penetration PV on the stability. However, for more accurate assessment of the transient stability, it is necessary to analyze various simulation models considering many other power system conditions. This paper presents the results of the analysis for the transient stability simulation performed for IEEE 9-bus system model, in which the effects of various conditions, such as variety of power sources (inverter or rotational machine), load characteristics, existence of LVRT (low-voltage ride-through) capability and fault locations, on the transient stability are investigated.

Abstract:The impact of large-scale grid-connected renewable power sources, such as wind generators and solar photovoltaic systems, on transient stability of synchronous generators is discussed in this paper. The permanent magnet synchronous generator with variable speed wind turbine is used in the simulation analysis as a wind generator model. The transient stability analysis is performed for IEEE 9-bus system model with high-penetration renewable power sources. The effect of FRT (fault ride-through) capability implemented for each power source on the transient stability is investigated.

“…Although there are some studies relating to the stability analysis using the power system model with infinite bus and PV system [3][4][5], few studies has focused on the influence of infinite bus on the transient stability. As the transient stability is mainly an instantaneous energy balance problem, it is important to consider the influence of the existence of LVRT capability and infinite bus on the transient stability.…”

Abstract:The impact of large-scale grid-connected PV (photovoltaics) on power system transient stability is discussed in this paper. In response to an increase of PV capacity, the capacity of conventional synchronous generator needs to be reduced relatively. This leads to the lower system inertia and the higher generator reactance, and hence, the power system transient stability may negatively be affected. In particular, the impact on the transient stability may become more serious when the considerable amounts of PV systems are disconnected simultaneously during voltage sag. In this work, the potential impact of significant PV penetration on the transient stability is assessed by a numerical simulation using PSCAD/EMTDC.
