Do STATCOMs have energy storage?
It is further shown that STATCOMs equipped with energy storages, due to the ability of controlling both active and reactive power, can keep the system performance practically una ected during the same conditions.
How does a STATCOM work?
In its basic structure, the STATCOM can only exchange reactive power with the grid, but if equipped with an energy storage, the STATCOM can also exchange active power. The performance and applications of STATCOMs are analysed in this work, however, the thesis is focused on STATCOMs used on distribution level.
What is E-STATCOM system?
This kind of system is termed “E-STATCOM” (energy storage + STATCOM), which has the ability to provide active and reactive power support for a specified duration . An E-STATCOM is formed by integrating an ESS into a power electronic converter.
Why is energy storage important in a STATCOM?
Furthermore, the energy storage also enables a STATCOM to support an entry into islanding operation, by rapid balancing of loads, after tripping of a single feeder. The nal part in the thesis treats dynamic loads and their impact on system performance. Dynamic loads of this type are not common in the power system today, but might be in the future.
Does the bandwidth of a STATCOM controller affect system performance?
Furthermore, it is shown that the bandwidth of the controller in a STATCOM, without energy storage, has a large impact on the stability of the system when connected to a dynamic load. The controller bandwidth has a much smaller impact on the system performance if the STATCOM is equipped with an energy storage.
Do E-STATCOMs work in power quality applications?
In this chapter has power quality applications, in which energy storage equipped STATCOMs are needed, been explained. It has been showed that an E-STATCOM can completely mitigated voltage dips and in particular the phase jumps associated with the dips. However, this only holds if the rating of the converter and the energy storage are large enough.
