Workflow

Here, we describe the terminology and the general workflow in more detail.

Terminology

We define the terminology used within this documentation, the code, and input data:

• Technology: a technology that produces, consumes, converts or transports energy
• Node: a site which can contain multiple technologies
• Line: a link between two sites that can carry energy between those sites
• Carrier: an energy carrier that groups technologies together into the same network, for example, electricity or heat
• Parameter: a fixed coefficient that enters into model equations
• Variable: a variable coefficient (decision variable) that enters into model equations
• Set: an index in the algebraic formulation of the equations
• Constraint: equality or inequality expression that constrains one or several variables

Workflow

The workflow for this package can be broken down to:

• Data Preparation
• Optimization

Data Preparation

CEP needs two types of data:

• Time series data in the type ClustData - Preparing ClustData
• Cost, node, (line), and technology data in the type OptDataCEP - Preparing OptDataCEP

They are kept separate as just the time series dependent data is used to determine representative periods (clustering).

Example Workflow

using CapacityExpansion
using Clp
optimizer=Clp.Optimizer # select optimizer

## LOAD DATA ##
# laod ts-data
ts_input_data = load_timeseries_data_provided("GER_1"; T=24, years=[2016])
# load cep-data
cep_data = load_cep_data_provided("GER_1")

## OPTIMIZATION ##
# run a simple
run_opt(ts_input_data,cep_data,optimizer)
