A multi-markets biding strategy decision model with grid-side battery energy storage system (BESS) as an independent market operator is proposed in this paper. First, the trading methods of BESS participating in the spot market are analyzed. on this basis, a two-layer transaction decision model is built with comprehensively considering the
To do this, all generation and storage sources are controlled in the grid-forming mode as voltage-controlled sources to follow a unified power-frequency (P-ω) droop curve. This P -ω droop curve is based on the microgrid frequency as an indicator index and adjusted locally in real time according to the available wind power, load demand, and SOC of the BESs.

1. Introduction Due to their advantages of fast response, precise power control, and bidirectional regulation, energy storage systems play an important role in power system frequency regulation (Liu et al., 2019), voltage regulation (Shao et al., 2023, Zhou and Ma, 2022), peak shaving (Li et al., 2019, Dunn et al., 2011, Meng et al., 2023a),
The optimal configuration of the rated capacity, rated power and daily output power is an important prerequisite for energy storage systems to participate in peak regulation on the grid side. Economic benefits are the main reason driving investment in energy storage systems. In this paper, the relationship between the economic indicators
