An integrated multi-energy flow calculation method for electricity-gas-thermal integrated energy systems

Abstract The modeling and multi-energy flow calculation of an integrated energy system (IES) are the bases its operation planning. This paper establishes models various sub-systems coupling equipment for electricity-gas-thermal IES, model IES is constructed. A simplified method compressor in a natural gas network, one which not included loop works constant compression ratio mode, also proposed based on concept reduction. In addition, numerical conversion dealing with conflict between nominal value per unit described. case study given to verify correctness speed method, interaction characteristics among studied.
