A novel switching control for a PV storage system with a GFL/GFM control structure was proposed in response to this challenge. By leveraging integrators and the state follower method, a smooth switching control strategy between these two control modes was facilitated, ensuring stable operation across varying grid strengths.
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. Transmission Line On-line Period Off-line Period Transmission Line 20
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.
A case study on a modified IEEE RTS-79 system is provided to validate the effectiveness of the proposed model. The results show that the BEST and TS have a synergistic effect on enhancing power grid flexibility, which reflects in this study as the power grid operating economics improvement and renewable energy curtailment reduction.
And when the BEST remains still as a fixed battery energy storage system, the achieved flexibility is 6.00%, which is the achieved flexibility in NCUC with BES scenario. That means the NCUC with BEST scenario will degenerate into the NCUC with BES scenario when the BEST transportation cost reaches a threshold. 4.5. Impact of BEST and TS on LMP
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.
