Optimization Method for Multi Energy Microgrid Operation Considering Carbon Emissions

Under the background of the "dual carbon" goal and the construction of a new power system, the development of microgrid with multi-energy has been promoted. However, considering the poor anti-interference ability of new energy and the uncertainty of source load, the quality of energy supply is reduced, which makes the safety risk of multi-energy microgrid and the economy of microgrid difficult to guarantee. Aiming at this problem, this paper proposes a multi-energy microgrid optimization method considering carbon trading. Firstly, this paper analyzes the energy supply, conversion and storage characteristics of each main body in the microgrid. Then, a low- carbon economic optimization operation model of multi-energy microgrid is established. On this basis, the research on multi-energy microgrid cluster is carried out according to the bi-level optimal operation system, and a multi-objective optimization algorithm of NC-MOPSO is used to solve the multi-energy collaborative interactive optimization objectives at the microgrid cluster level and the single microgrid level. Finally, the feasibility of the multi-energy microgrid optimization method proposed in this paper is verified by an example simulation.
