Some works study the direct power prediction of renewable energy, as the power outputs or power distributions are easily used in spot market bidding. Vilim et al. (2014) captured the price effects of wind power production and consumption using a stochastic market model, and the predictions of wind power outputs and market prices
AbstractThe reform of power spot market in China provides a new profit mode, determining energy trading strategy based on the power spot prices for distributed energy storages. However, individually accessing every distributed energy storage to the dispatch centre results in a high cost and low efficiency, which needs to be improved by
1. Introduction The debate on what roles can energy storage support in the power sector and contemporary electricity markets has been prominent for more than a decade [1] spite the fact that such systems can provide a bundle of services [1], [2], including avoidance of costly interconnecting infrastructure and emission reduction [3],

When energy storage participates in power spot market transactions, the Stackelberg game bidding model can be used to solve the trading and regulating behavior of energy storage in the short-term market. In the Stackelberg game, the bidding model of
The revised rules now encompass a broader range of market participants, including power market operators, grid companies, provincial-level power trading
At present, China''s power trading mainly includes medium- and long-term power trading and power spot trading, while moderate liberalization of frequency regulation, peak regulation, and other auxiliary services
Moreover, as renewable energy penetration escalates, the issue of reserve undeliverability due to transmission congestion diminishes the power system''s capacity to utilize renewable energy resources. To address this concern, this study introduces a secondary clearing mechanism for the electricity spot market, taking into account the
As an important part of the electricity market, the spot market is open between the day before the real-time operating day and the real-time operation, and
