PyPSA: Open Source Python Tool for Load Flow Study

Abstract

PyPSA is a Python-based open-source tool used for load flow analysis in the power system. PyPSA (Python for load flow analysis) is a leading tool, which is convenient for simulation and optimization of the power system network. It is a free software which regulates parametric valuation along with multi-temporal analysis in the power system. The Modern power system is the integration of various devices like Generators, Transformers, Bus bar, lines Protecting devices and load connected through it. Load flow analysis is used to determine the different types of parameters in the power system i.e. Voltage Magnitude, Phase angle, Power injected, power output and losses through the power system etc. Various kind of devices is utilised in modern power system analysis. Conventionally many techniques are adopted for power System analysis i.e. Mathematical modelling of the system and then calculation. These techniques consume very much time for the calculation. But, due to the advantage of Science and Technology, different types of new methods are developed. PyPSA is one of them. These methods are accurate, fast and reliable for power system analysis. In this study, PyPSA tool is used to analyse the IEEE 12 bus system for determining the voltage magnitude across each bus.
