Research on Optimal Dispatching of Multi-energy Flow System Considering Heat Network Loss under Different Optimization Objectives

摘要

For multi-energy flow system, optimal dispatching can make full use of the advantages of multi-energy coordination and complementarity by rationally arranging the planned output of different energy supply systems to ensure the optimal operation of the system. In this paper, the optimal economic benefit of the whole system operation or the lowest pollution emission cost are taken as the optimization objectives. On the basis of the existing electric and heating coordinated operation dispatching model, the network balance equation and branch characteristic equation of the heat supply network model are analyzed. The influences of transmission loss are used as constraints. Finally, according to an actual example, the influence of network transmission loss on the optimization results under different optimization goals is analyzed.
