Operation optimization of energy complementary collaborative energy storage system in cold chain logistics park
The rapid development of the cold chain logistics industry has promoted the construction of cold chain logistics park.The energy system of cold chain logistics park can produce,store and distribute various forms of energy such as cold,heat and electricity.To further optimize the energy system of cold chain logistics parks,the multi-energy collaborative operation optimization method and the energy cascade utilization method can be adopted.In this paper,an optimal scheduling scheme combining the multi-energy complement and the energy cascade utilization has been proposed for a cold chain logistics park.Considering the actual equipment demand of the park,an energy supply model has been established.The daily operating cost and the stability of the load were set as the optimization goal.The model was solved by the mixed integer mathematical linear programming method.The results showed that the combining scheme can realize the ener-gy supply of the cold chain logistics park which centered on the cooling capacity.Compared with the original energy system,the operation cost can be reduced by 5.2%,and the stability of the cooling load can be increased by about 10%.
