Enerallt

This repository hosts Enerallt, a multi-country power market and district heating model, developed and maintained by The Energy Efficiency and Systems Laboratory, Department of Mechanical Engineering, Aalto University, Finland. The model is an hourly simulation of the operation and dipatch of electricity and district heating (DH) production in a group of countries (or price areas) that are interconnected together in a common power market. The model in this repository is calibrated to data of the Nordic power market, including Finland, Norway, Sweden, West Denmark, and East Denmark.

The main features of the model include:

1. Simulation of hydropower water values at the country level

2. Modelling of hourly district heating (DH) demand and supply, and the operation of combined heat and power (CHP) plants in both electricity and DH markets

3. Electricity market clearance based on the day-ahead planning horizon for up to 365 days. The adaptative strategies of some of power producers is modeled; i.e., these producers adjust their future bids based on the outcome of the market in the past runs, assuming a limited foresight.

Hence, the model doesn't seek to find the optimal solution for a yearlong period benefiting from a perfect foresight. The model can be used to investigate the most probable operation and outcome of an nternational power market, when there exists no central planning.

Usage and requirements

For using the model, you need MATLAB and under a valid license. Enerallt is licensed under Apache 2.0 (see License file for more details). To start working with the models do the following:

1. Download the folder that you are interested, e.g., "Enerallt_regular".
2. Open the interface file in MATLAB and run it for your desirable number of days. The models come with some default input data and calibration. The scripts are partly explanatory, but we will add a more straighforward documentation.
