A Multi-Microgrid Energy Trading Strategy to Achieve Carbon Neutrality

Nowadays, microgrids (MGs) face complex energy trading challenges due to the progress of energy decarbonization and liberalized carbon markets. This paper proposes a robust trading strategy for multiple MGs to facilitate achieving carbon neutrality. Firstly, a bi-level Stackelberg game model is established and transformed into a single-level model using the karush-kuhn-kucker (KKT) method to improve the solution's efficiency. Afterward, a Nash bargaining method is employed to ensure a fair distribution of the benefits of each MG. Finally, the alternating direction method of multipliers (ADMM) algorithm solves the model and finds the optimal results. The effectiveness of the proposed strategy is verified by simulation in Matlab.
