Abstract:

Electricity transaction of multi-microgrid system enables to improve the overall economy, alleviate the operating pressure of distribution network and promote the consumption of renewable energy. Nevertheless, the transactions of multi-microgrid system are obliged to process large-scale, complex structure, and highly real-time data of microgrid. Therefore, taking the uncertainty of wind power output into consideration, this paper puts forward a robust game bidding scheduling model for multi-microgrid system applying blockchain technology with data transparency and reliability. Firstly, the compatibility between the blockchain technology and the non-cooperative game model of multi-microgrid electricity transaction is analyzed. And then the paper establishes a multi-microgrid transaction architecture based on blockchain technology. Binary expansion method, duality theory, big M method, and C&CG algorithm are employed to achieve the optimal economic dispatch strategy and bidding strategy of each microgrid. Finally, the paper builds a transaction platform based on blockchain technology, and the corresponding case studies verify the effectiveness of the proposed method.

Key words: blockchain, multi-microgrid system, wind power uncertainty, two-stage adjustable robust model, non-cooperative game
