Abstract: 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.
The bidding strategy of energy storage power station formulated in most papers relies on the day-ahead predicted price and regulation demand, and the effectiveness of the bidding strategy is based on the premise that day-ahead forecast is accurate [9, 10, 11].
In recent years, battery energy storages stations (BESSs) account for the largest proportion in large-scale energy storage power station projects due to its advantages such as rapid response, high integrated power, decreasing cost year by year and short construction cycle.
This marks the completion and operation of the largest grid-forming energy storage station in China. The photo shows the energy storage station supporting the Ningdong Composite Photovoltaic Base Project. This energy storage station is one of the first batch of projects supporting the 100 GW large-scale wind and photovoltaic bases nationwide.
Going forward, various tests and performance experiments will be carried out to provide data support for the testing and standard setting of grid-forming energy storage.
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.
