In the last year, there have been new developments in pandapower and pandapipes. We describe the most important new features that were added after the release of pandapower version 2.6.0 and pandapipes version 0.4.0. This paper refers to pandapower’s latest version 2.12.0 and pandapipes’ latest version 0.8.4 and is organized as follows. First, we introduce the new features of pandapower. We added a new module to simulate protection devices. Furthermore, we added the implementation of static grid equivalents. Groups of elements will be useful to modify or obtain results for several elements at once. In addition, we extended the power flow calculation in pandapower by two Flexible AC Transmission System (FACTS) devices and by Temperature-Dependent Power Flow (TDPF). We further improved the short-circuit calculation and added voltage as a result in order to enable the implementation of distance protection in the future. Finally, we added a converter from DigSILENT PowerFactory to pandapower. A further converter we added can be used to import a CIM CGMES dataset to pandapower. As for pandapipes, we improved its performance through just-in-time compiled functions. Furthermore, new component types were added, including pressure regulator, flow control, and compressor. Finally, a converter from STANET to pandapipes was added.enpower system modelingpower system protectiontemperature-dependent power flowFACTS devicesdistrict heatingpresentation
