i still playing around with operate mode, does have energy_cap_max at transmission technology any impact an the results ? i does not look like that ...
energy_cap_max is not really suited for operate mode, as it limits the maximum capacity the optimization procedure can allocate to a given technology in a given location.
and the "operate" mode does not perform any optimization on the installed capacities, only the "plan" mode
my names Mark, I am new here. Currently, I am about to finalize my research proposal for my PhD, for which I will at some point create an energy system model. Which is why I stumbled upon calliope.
So far I still did not understand what calliope is really doing. I get that I can build my model (regions, demands for power / electricity, supply / energy production and transmission lines). But what is the part of the solver? What does it solve?
Hi everyone, I'm trying to update my old models to the latest functionality and I'm a little confused over how 'export' now works. Let's say I have some excess free power available in a model (e.g. some wind power that is beyond what is required to meet the demand in the model), and I want to be able to convert this spare energy into another carrier which has an external value. For the sake of an example, we have a machine which converts power into magic beans which are worth $1000/kWh of beans. I could state this as follows:
magic_bean_maker: essentials: name: 'Magic bean maker' color: '#3B61E3' parent: conversion carrier_in: power carrier_out: magic_beans export_carrier: magic_beans constraints: energy_eff: 1.0 lifetime: 25 costs: monetary: interest_rate: 0.10 energy_cap: 0 # USD per kW om_con: 0 export: -1000
However, when I put this into a model with
energy_cap_equals: 1000 at a location with free power, despite there being no cost to producing beans and a clear negative cost to exporting them, no beans are produced. Is this because there is no demand for beans defined anywhere in the model, and the framework can only optimise for carriers with a demand?
