摘要：
The distributed power market trading model can effectively alleviate the problems among market entities such as privacy problem in the traditional centralized trading model. However, there is still a lack of distributed trading models that can maximize social welfare while ensuring the benefits of market entities and the safe and stable operation of the power system. Therefore, a centralized trading model with the objective of maximizing social welfare is constructed, which considers the power grid line transmission security. Then, it is equivalently decomposed into a distributed trading model that maximizes the interests of each market agent using the Lagrange multiplier method and dual duality theorem. On this basis, two distributed trading methods and the corresponding solution algorithms suitable for different scenarios are designed, and the grid security cost is used to influence the decision-making of market entities, thereby ensuring grid line transmission security. Finally, the effectiveness of the two trading methods are verified based on simulation analysis. © 2024 Science Press. All rights reserved.
