FAQS about Energy storage system bidding strategy

How effective is the bidding strategy of energy storage power station?

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].

What is the proposed bidding strategy?

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.
