The multi-objective problem above is addressed through Stackelberg game, as shown in Fig. 3, where the EVA, as the game leader, aims to maximize its income and minimize the load peak-valley difference by searching optimal dynamic electricity price for next day; EVs, as game followers, optimize the charging and discharging

The peak-valley price difference affects the capacity allocation and net revenue of BESS. As shown in Table 5, four groups of peak-valley electricity prices

To support long-term energy storage capacity planning, this study proposes a non-linear multi-objective planning model for provincial energy storage

Distributed energy storage systems owned by users can benefit from the difference between peak and valley electricity prices by discharging during peak hours and charging during valley hours. The economic model for this process, known as peak-shaving and valley-filling, can be expressed as follows: (7) C Peak 2 Valley = ∑ n = 1 365 ∑ t = 0

Data centers have high electricity load and power consumption, while the electricity cost accounts for 30–50% of the total operating cost. In this paper, the peak

Abstract: In order to make the energy storage system achieve the expected peak-shaving and valley-filling effect, an energy-storage peak-shaving scheduling strategy

The combined operation of hybrid wind power and a battery energy storage system can be used to convert cheap valley energy to expensive peak energy, thus improving the economic benefits of wind farms. Considering the peak–valley electricity price, an optimization model of the economic benefits of a combined

Due to the popularity of power supply and power facilities, local governments have issued a series of coal-to-electricity policies, including power allocation, energy storage, and reduction of peak and valley electricity prices. Electric heat storage and air source heat pump has been widely promoted and applied (Cai et al., 2020; Xu et

Guangxi''s Largest Peak-Valley Electricity Price Gap is 0.79 yuan/kWh, Encouraging Industrial and Commercial Users to Deploy Energy Storage System. The World''s First Salt Cavern Compressed Air Energy Storage Power Station Officially Enters Commercial Operation. Older Post Shandong Revises the Operating Rules of the Power

Based on the antipeak-shaving characteristics of new energy, ES revenue will primarily rely on "peak cutting and valley filling" to earn the peak-valley price difference in the next few years. It earns subsidies by working as

In summary, the virtual price of energy storage use is set as E p s t − j = E p m + 0.01. To ensure that prosumers first sell electricity in the LEM before storing and then sending the excess to the grid, we set the virtual price of energy storage slightly lower than the feed-in tariff given by E p j − s t = E p s − g − 0.01.
