An open dispatch model for the Nordic power system

Abstract

This paper presents ODIN, an open dispatch model for the Nordic power system. We begin by performing a survey of existing models, and conclude that no model which simulates the different price areas in the Nordic power system and is truly open exists. Existing models either lack data to do an out-of-the-box simulation which accurately represents the Nordic power system, rely on proprietary software, or have a more coarse representation of the Nordic region. In contrast, ODIN has the following properties: (1) It is developed completely in Python and can be solved with open-source optimization tools, thus using no proprietary software. (2) It includes all data needed to do yearly simulations for the Nordic power system, with 35 years of data for weather-dependent production such as hydro power and wind power. (3) It represents all Nordic price areas and has been validated to reproduce historical production and transfer patterns. This paper describes the methodology and structure of the model and illustrates its features with examples and a case study.
