A Joined Quasi-Steady-State Power Flow Calculation for Integrated Energy Systems

The network storage capability of district heating systems and gas can provide a considerable flexibility in integrated energy systems, increasing the use volatile renewable generation. But stronger single are linked more complex their operation becomes due to increased interactions. To ensure secure reliable system while using full potential these interactions must be analyzed. Existing power flow calculation methods, however, assume steady-state behavior all system, neglecting capability. Hence, this paper presents joined quasi-steady-state method for systems. Our introduces dynamic arising from temperature propagation compressibility hydrogen. In comparison with we show effect on an system. As our enhances existing it easily used same cases but allowing investigated.
