What is the new STATCOM for distributed power?

The new STATCOM for distributed power now supports any requirement from 3MVAr to 20MVAr. It joins our wide portfolio of products, systems and solutions overcoming the world’s power quality challenges. We connected Dynamic Reactive Compensation with Hitachi SVC Light HP, the most powerful STATCOM on the market.

Are battery energy storage systems making “green” energy possible?

As battery development continues to improve and renewable energy sources become more important in power distribution, it is not surprising that Battery Energy Storage Systems (BESS) are playing a larger role in making “green” energy possible.

What is state-of-charge balancing among distributed energy storage modules?

State-of-charge (SoC) balancing among distributed energy storage modules: The SoC of the distributed storage modules may diverge from each other due to differences in their operating conditions and manufacturing tolerances.

Does E-STATCOM provide a negative sequence current?

The E-STATCOM at the PCC provides a negative sequence current component and makes the grid current balanced. The corresponding controller that provides negative sequence currents is shown in Fig. 10.8. The per-phase equivalent circuit of the grid-connected wind farm with an E-STATCOM is given in Fig. 10.12.

Which energy management system is supplied by the BSS?

An energy management system (EMS) is presented in Fig. 10.14, and active power supplied by the BSS is given in Fig. 10.21. From the figure, it can be noticed that the low-frequency component of the E-STATCOM is supplied by the BSS and the remaining power is given by UC modules.

How do you find the SOC of a battery module?

The SoC of a battery module can be determined as: (10.25) S o C i = 1 C b a t n o m ∫ 0 t i b a t (t) d t where C b a t is the nominal capacity of the respective battery module and i b a t is the current associated with the battery module.
