Many of the tools currently used for power system modelling were written in the era before widespread integration of renewable energy and the electrification of transport and heating. The increasing complexity of the electricity system requires new tools for power system modelling. In addition, the increasing deployment of storage technologies introduces many network users which are both consumers and generators of energy. On the demand side, the need to decarbonise the transport and heating sectors is leading to the electrification of these sectors and hence higher electrical demand, replacing internal combustion engines with electric motors in the transport sector, and replacing fossil fuel boilers with heat pumps, resistive heaters and cogeneration for low-temperature space and water heating. On the generation side, variable renewable generation causes loading in parts of the grid where it was never expected, and introduces new stochastic influences on the flow patterns.

The importance of software modelling of the grid has risen in recent years given the increase in distributed and fluctuating wind and solar generation, and the increasing electrification of all energy demand.
Power system tools model the interactions between the electrical grid and the consumers and generators which use the grid. The responsibility for the contents lies solely with the authors The functionality is demonstrated on two open datasets of the transmission system in Germany (based on SciGRID) and Europe (based on GridKit).įunding statement: This research was conducted as part of the CoNDyNet project, which is supported by the German Federal Ministry of Education and Research under grant no.

PyPSA is positioned in the existing free software landscape as a bridge between traditional power flow analysis tools for steady-state analysis and full multi-period energy system models. In this paper the basic functionality of PyPSA is described, including the formulation of the full power flow equations and the multi-period optimisation of operation and investment with linear power flow equations. It is designed to be easily extensible and to scale well with large networks and long time series. PyPSA includes models for conventional generators with unit commitment, variable renewable generation, storage units, coupling to other energy sectors, and mixed alternating and direct current networks. Python for Power System Analysis (PyPSA) is a free software toolbox for simulating and optimising modern electrical power systems over multiple periods.
