Abstract:

For multi-load multi-source microgrid systems, energy management and collaborative control are one of the keys to ensuring reliable operation of the system. A collaborative optimization method with the minimum operating cost and minimum carbon emission of the system as joint optimization goals is proposed. The mathematical model for the working characteristics of each key equipment in the system is establised,and the Yalmip optimization toolbox in MATLAB is used to calculate the operation status of each key equipment. Typical load data in winter are used as model input for the simulation example. The simulation results show that the constructed collaborative optimization model can meet the optimal operation of the microgrid in a demand response environment. The simulation results verify the accuracy and effectiveness of the model.
