CI codecov PyPI version Python versions License: MIT Documentacao

O inewave é um pacote Python para manipulação dos arquivos de entrada e saída do programa NEWAVE. O NEWAVE é desenvolvido pelo CEPEL e utilizado para os estudos de planejamento e operação do Sistema Interligado Nacional (SIN).

Funcionalidades

  • Leitura e escrita dos arquivos de entrada do NEWAVE, com suporte a modificações programáticas de decks de PMO
  • Leitura dos arquivos de saída do NEWAVE e dos programas auxiliares NWLISTCF e NWLISTOP
  • Dados tabulares expostos como DataFrame do pandas, prontos para análise e visualização
  • Interface orientada a objetos consistente: cada arquivo corresponde a uma classe com método read e, quando aplicável, método write
  • Suporte a múltiplas versões de formato do mesmo arquivo, com seleção via argumento version= no método read
  • Importação sob demanda (lazy import) para inicialização rápida mesmo com dezenas de classes disponíveis

Exemplo Rapido

Leitura do arquivo de saída pmo.dat e acesso aos dados de convergência como DataFrame:

from inewave.newave import Pmo

arq_pmo = Pmo.read("./pmo.dat")
arq_pmo.convergencia

Leitura de um arquivo de entrada, modificação de valores e escrita do resultado:

from inewave.newave import Vazoes

arq_vazoes = Vazoes.read("./vazoes.dat")

# Sensibilidade: elevar todas as vazões históricas em 10%
arq_vazoes.vazoes *= 1.1

arq_vazoes.write("./vazoes_sensibilidade.dat")

Instalacao

O inewave é compatível com Python 3.11, 3.12, 3.13 e 3.14.

Instalação a partir do PyPI:

pip install inewave

Instalação da versão de desenvolvimento diretamente do repositório:

pip install git+https://github.com/rjmalves/inewave
