Python for Power System Analysis (PyPSA): Free Software for Planning Energy Systems with High Shares of Renewables

摘要: Python for Power System Analysis (PyPSA) is a free software toolbox for simulating and optimising modern power systems over multiple periods. PyPSA includes models for conventional generators with unit commitment, variable wind and solar generation, storage units, coupling to other energy sectors, and mixed alternating and direct current networks. It is designed to be easily extensible and to scale well with large networks and long time series. In this paper the basic functionality of PyPSA is described, including the formulation of the full power flow equations and the multiperiod optimisation of operation and investment with linear power flow equations. 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. The functionality is demonstrated on two open datasets of the transmission …
