Competition game model for local multi-microgrid market based on block chain technology and its solution algorithm

Block chain technology as a new distributed database technology has great application potential in the energy filed. As an important component of the energy internet, the research on the competition game of multi participators in the multi-microgrid system is of great significance to the development of energy internet technology. The market demand and profits of microgrid operators, big consumers and distributed aggregators are comprehensively ana-lyzed, and the competition game model for the local multi-microgrid system is proposed based on the block chain technology, which is solved by the IACO(Improved Ant Colony Optimization algorithm). The proposed competition game model and the solution algorithm are simulated and results show that, the optimal electricity price strategy of each period obtained by the proposed model can effectively balance the benefits among market participators, realizing the win-win and coordinated development, and the adaptability and effectiveness of IACO in solving the multi-objective optimization problem based on the block chain technology are verified.
