Market Participation of Energy Storage Systems for Frequency Regulation Service: A Bi-level Model Abstract:This paper examines the prospect of using the energy storage systems (ESSs) in the distribution network for frequency regulation service under the two-settlement market mechanism.
Flow chart of bidding strategy of BESS in DAM and RTM 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.
The bidding strategy for BESSs to participate in the frequency regulation market proposed in this paper is based on the market process shown in Fig. 1. In DAM, the power grid operator determines the bid-winning unit of the next day according to the supply function curve reported by each power generator.
Usually the real-time output of BESS in the frequency regulation market is less than its bid-winning capacity. Taking PJM market as an example, the real-time RegD signal is a normalized instruction, and its value ranges from −1 to 1. The value multiplied by the bid-winning capacity is the real-time output of the BESS.
