Electricity demand view (MW)

indexed by: asset, energy, demand_type, node, technology and test case

Description

This KPI is used to analyse the differences between the unoptimized electricity demand of pure demand assets and their optimised demand.

Some electricity demand assets can be flexible and can therefore optimise their demand under certain constraints. It is therefore interesting to understand the difference between optimised and non-optimised demand in order to understand the impact of the asset’s flexibility. For instance, this helps to analyse peak shavings or loads shedding over larger periods.

Note

This KPI only focuses on pure electricity demand assets: power demand assets, electric vehicles, heat-pumps, demand-response and interruptible load.

Calculation

All the equations below are valid for any realization and are therefore implicitly indexed by test case.

For flexible electric vehicles, flexible heat-pumps, flexible demand response and interruptible load, demand is optimized and then optimized demand and unoptimized demand can be different. In these cases:

• Unoptimized demand is an input. This is either a direct input from the model for demand response and interruptible load or computed by coe_datalib library thanks to other inputs for electric vehicles (arrivals, departures, discharge) and heat-pumps (heating demand).

• Optimized demand is a model output: \(c_{a,e,n}(t)\)

For other pure electricity demand asset whose demand is exogenously fixed and not optimized, both the optimized demand and the unoptimized one are equal. In these cases, both the optimized and the unoptimized demand are model inputs.

Indexing

• The asset index refers to the name of the asset

• The energy index is the energy stored by the asset

• the demand type index refers to the nature of the demand, whether it is optimised or not

• The node index of this KPI refers to the consumption node of the asset

• The technology index refers to the technology type of the asset

• The test case index corresponds the test case of the realization variables and parameters are taken from
