In electricity networks, the loss of a large energy generator (e.g. a nuclear power plant), can cause a rapid frequency decline. The kinetic energy in synchronously-connected generators slows the rate of change of frequency, providing a time buffer for quick-start generators or load resources to correct the imbalance in supply and demand .
SPVGs can also be used to inject reactive power to the grid. However, the presence of SPVG in a network can cause system/voltage instability 3, 4, which makes imperative that voltage stability be accounted for when connecting SPVG generators to the grid.
As levels of non-synchronous energy generation increase and synchronous generators continue to retire, system inertia levels are expected to fall. This might introduce a level of vulnerability to failure that could make the grid inoperable, especially as renewable energy penetrations pass 80% of annual energy demand and approach 100%.
In this paper, three static techniques are applied to show the impact of SPVG or/ and FACTS devices on voltage stability of power grids. Also, the optimum location of FACTS devices in the power system with and without SPVG will be obtained under nominal and heavy load conditions. The proposed approach is illustrated in the flowchart in Fig. 5.
