Integrated Heat and Electricity Dispatch for District Heating Networks With Constant Mass Flow: A Generalized Phasor Method

Using thermal inertia in district heating systems (DHSs) to improve the dispatch flexibility and economy of integrated heat electricity (IHESs) is a research hotspot difficulty. In most existing studies, partial differential equations (PDEs) are approximated by discrete-time models, making it difficult accurately describe continuous dynamic processes. this paper, we propose novel generalized phasor method (GPM) for DHSs with constant mass flow. Based on analytical solution PDEs Fourier transform, intractable transformed into series complex algebraic represented phasors. The GPM has higher accuracy compared traditional discrete models because essentially model time domain. Then, present different representation an (IHED) combining DHS form electrical power system model. IHED convex programming problem can be easily solved. effectiveness proposed verified three test systems. Compared methods modeling inertia, more accurate.
