How AA-CAES Auxiliary Service works?

PS auxiliary service In response to the demand for the seasonal peak load reduction, ESS is combined with thermal power units for deep PS. The participation of AA-CAES in PS can alleviate the supply-demand imbalance and improve the economical operation of the system.

How can Hess respond to multiple auxiliary service markets?

Compared with existing methods, we propose a joint optimal dispatching strategy for HESS to provide local services for DG and respond to multiple auxiliary service markets from the perspective of maximizing aggregation benefits. The auxiliary market considers multiple revenue streams, including PS, FCR, and SFR.

Can EV aggregation participation improve the ancillary service market responsiveness?

Finally, taking EV aggregation participation in the valley-filling ancillary service market as an example, it is verified that the strategy proposed in this paper can effectively improve the responsiveness of EV participation in the ancillary service market and increase the revenue of electric vehicle aggregator (EVA).

Which auxiliary service market has a higher scheduling priority?

Research shown that in auxiliary service markets, the FR market has a lower capacity demand threshold, but the return on investment is considerable. Therefore, it often has a higher scheduling priority . In FR markets, Bahloul et al. adopted a hybrid power sharing method to optimize the fast frequency response performance of HESS.

Does auxiliary market consider multiple revenue streams?

The auxiliary market considers multiple revenue streams, including PS, FCR, and SFR. The main contributions of this study are summarized as follows: Constructs a joint optimal framework of a HESS for DG electricity production and multiple auxiliary service markets.

What is SFR Auxiliary Service?

SFR auxiliary service When the system frequency stability requirement cannot be met after FCR, the Automatic Generation Control System (AGC) sends instructions to market participants, providing SFR to handle slower frequency fluctuations and ensure the FR capability of the system.
