Against the power flow calculation problem of combined electric and thermal for integrated energy system

firstly

a two-way coupled power flow model with two combined heat and power(CHP) unit coupling nodes is established based on the two-way coupling. Then

the influence of coupling state of the electric boiler and the change of the system load on the system power flow is analyzed. Finally

a regional integrated energy system is selected for case analysis

and MATLAB is used to solve the combined power flow based on the Newton Raphson sequence algorithm. The results show that

the coupling nodes CHP1 and CHP2 interact with each other to achieve power flow balance

which verifies the validity of the model. The power flow of combined electric and thermal changes with the coupling state of electric boiler and the system load

which shows the source network load interaction characteristics of multi energy flow system. Research on power flow of the combined electric and thermal network can provides guidance for planning and operation of the electric heat coupling comprehensive energy system

and provides ideas for further research on the multi energy flow coupling power flow.
