Usually, the lower limit of the price declaration stipulated by the electricity market is zero or even negative, which provides the opportunity for the power generators participating in the market to take risks. Generators participating in bidding should choose different levels of risk aversion so as to develop different bidding strategies.
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.
According to the analysis in Sect. 5.1, the most reliable bidding strategy for each BESS at this time is to declare its marginal cost curve as its supply function, so as to determine its own frequency regulation mileage quotation and capacity. Therefore, in this case, the five BESSs take their marginal costs as the declared supply function.
