The bidding strategy of energy storage power station formulated in most papers relies on the day-ahead predicted price and regulation demand, and the effectiveness of the bidding strategy is based on the premise that day-ahead forecast is accurate [9, 10, 11].
Aiming at the multi-time scale clearing mechanism of the actual frequency regulation market, this paper divides the bidding strategy of BESSs to participate in the frequency regulation market into two stages: day ahead market (DAM) and real time market (RTM). The remainder of this article is organized as follows.
The proposed bidding strategy considers both energy market and regulation market, which shows flexibility to the uncertain bidding environments. The proposed algorithm is an individual profit maximisation bidding strategy, which can help the BESS owner optimise its bidding strategy to obtain highest bidding revenue without rivals information.

Frequency Regulation (or just "regulation") ensures the balance of electricity supply and demand at all times, particularly over time frames from seconds to minutes. When supply exceeds demand the electric grid frequency increases and vice versa. It is an automatic change in active power output in response to a frequency change.
