In this paper, the bidding strategy of energy storage in the flexible ramping market with imperfect competition is investigated. According to whether the bidding strategies have impacts on the market clearing results, market participants can be divided into two types, i.e., price taker and price maker [9].
Profit optimization is based on electricity price prediction and effective trading strategies that match the projected electricity prices.
Shared energy storage (SES) has become an attractive approach to utilize energy storage in energy systems, which is the application of sharing economy in energy storage [[19], [20], [21]]. Compared with traditional energy storage, SES can reduce the cost inefficiency and make better use of energy storage by separating the ownership
A more clear view of the applied methodology is provided in Fig. 2, where the different problem dimensions are illustrated.Additionally, a short description of the current status of energy storage (Section 3.1) and of the two storage technologies examined (Section 3.2) is provided in the following sections, along with an analysis of
It is urgent to establish market mechanisms well adapted to energy storage participation and study the operation strategy and profitability of energy
The efficiency of adiabatic compressed air energy storage technology is limited by the low utilization of thermal energy in the energy storage room. Therefore, a pumped hydro-compressed air energy storage system combined with a compressed air energy storage system as a spray system is introduced in the present research and
This paper addresses the trading strategy of independent energy storage station participating in both energy market and frequency regulation market. A restrictive
Bid structures delimit the level playing field in electricity markets. • We study their impact on the market participation of strategic energy storage owners. • Assuming perfect foresight, bid structures do not limit market participation. • Assuming limited foresight
We define a microgrid with 4 prosumers and 1 power plant, dividing a day into 8 transaction time blocks, one transaction time block lasts 3 hours. Prosumers'' generation, load, and unit price of electricity in a microgrid using the model in [4] g. 2 shows the average generation and average load of prosumer 1 during the day. . The
PHES was the dominant storage technology in 2017, accounting for 97.45% of the world''s cumulative installed energy storage power in terms of the total power rating (176.5 GW for PHES) [52]. The deployment of other storage technologies increased to 15,300 MWh in 2017 [52] .
CSES involves multiple consumers or producers sharing an energy storage system. This work presents an optimal strategy for CSES operators and

1 Introduction As early as September 2020, China proposed the goal of "carbon peak" and "carbon neutrality" (Xinhua News Agency, 2020).As a result, a new power system construction plan with renewable energy as the primary power source came into being (Xin et al., 2022).).
As of 2018, the energy storage system is still gradually increasing, with a total installed grid capacity of 175 823 MW [ 30 ]. The pumped hydro storage systems were 169557 GW, and this was nearly 96% of the installed energy storage capacity worldwide. All others combined increased approximately by 4%.

Finally, to the author''s knowledge, this is the study in the field of energy storage that simultaneously considers policy, technological innovation uncertainties, and investment strategies. Therefore, this paper is helpful and contributes to firms and policymakers in 1.
To this end, consider an energy storage device which is used for energy trading in a typical power network which consists of loads, conventional, and renewable power plants as shown in Fig. 1. The device is assumed to be lossless, the power flowing into the device is P ( t ), the price of energy is C ( t ), and the device capacity is E max .
To date, various energy storage technologies have been developed, including pumped storage hydropower, compressed air, flywheels, batteries, fuel cells, electrochemical capacitors (ECs), traditional capacitors, and so on (Figure 1 C). 5 Among them, pumped storage hydropower and compressed air currently dominate global
