6 FAQs about [New energy battery matching method on the transmission and distribution side]
What is battery energy storage transportation (best) & transmission switching (TS)?
To enhance the transmission system flexibility and relievetransmission congestion, battery energy storage transportation (BEST) and transmission switching (TS) are two effective strategies. In recent years, battery energy storage (BES) technology has developed rapidly.
Should best and ts be applied in the power grid?
Applying both BEST and TS in the power grid would promote each other to consume more renewable energy and relieve the transmission congestion, which enhances the flexibility of the power grid. Table 4. Working status of transmission lines with TS in NCUC with BEST+TS. Fig. 11.
Can battery energy storage systems be transported within a power system?
The battery energy storage systems in the power system were always regarded as stationary systems in the past. When considering that battery energy storage systems could be transported within the power system, the BEST would further enhance the economics and security of power system operation.
Can best and TS improve the flexibility of the power grid?
We can conclude that the cooperation of BEST and TS could greatly enhance the flexibility of the power grid from the transmission side, which is reflected as a substantial overall operating cost reduction and a lower renewable energy shedding ratio.
Does ncuc reduce transmission losses during 24 h?
The transmission congestion may bring power system security problems. In that case, although NCUC with BEST+TS has greater transmission losses, it relieves the transmission congestion, which improves the security of the system and has greater application potential. Fig. 13. Overall transmission losses during 24 h in NCUC with BEST+TS and NCUC.
What is flexible alternative current transmission system (FACTS)?
Flexible alternative current transmission system (FACTS) is an effective technology to enhance transmission system flexibility, which has been invented and increasingly deployed to control power system parameters, such as voltage magnitude and phase, shunt susceptance, and transmission line impedance .
