lineoptim 1.1.1

A line optimization package for electrical conductors.

LineOptim - Electric Power Line Parameter Optimization

lineoptim is an open-source package for electric power line simulation and optimization. It provides the tools for simulating, visualizing and optimizing electric power lines and is designed to scale with larger and nested networks.

Features

• Line Simulation: Simulate electric power lines with multiple loads and sub-lines. Get voltage drop, current power at any point in the line.
• Optimization: Optimize electric power lines for wanted voltage drop and optimal conductor size
• Visualization: Visualize electric power lines and their parameters

Installation

pip install lineoptim

Usage

import lineoptim as lo
import torch

# Create a line
v_nominal = torch.tensor([400.0, 400.0, 400.0])  # nominal voltage

line_params = {
    "name": "Main power line 1",
    "position": 0,
    "resistivity": torch.tensor([0.12, 0.12, 0.12]),  # resistivity,
    "reactance": torch.tensor([0.0, 0.0, 0.0]),
    "v_nominal": v_nominal,
}

# create main line
main_line = lo.Line(**line_params)

# add loads to main line
main_line.add("Load 1", 100, active_power=20000, v_nominal=v_nominal, power_factor=0.9)
main_line.add("Load 2", 200, active_power=20000, v_nominal=v_nominal, power_factor=0.9)
main_line.add("Load 3", 300, active_power=20000, v_nominal=v_nominal, power_factor=0.9)

# create sub-line
sub_line = lo.Line('Sub-line 1', 400, v_nominal=v_nominal, resistivity=torch.tensor([0.145, 0.145, 0.145]))

# add loads to sub-line
sub_line.add("Load 4", 410, active_power=2000, v_nominal=v_nominal, power_factor=0.9)

# add sub-line to main line
main_line.add(**sub_line.dict())

network = lo.Network()  # create network
network.add(main_line)  # add line to network

network.optimize(epochs=200, lr=0.01, max_v_drop=5.0)  # optimize network on 5% voltage drop at line ends

main_line.save_to_json('resources/example_line.json')  # save line configuration as json
