# Scenario/set

> Set properties of a `Scenario` instance

---

## Description
Set properties of a `Scenario` instance.
This results in `valid = false`.

## Syntax
```matlab
scenario = set(scenario,Name=Value)
scenario = scenario.set(Name=Value)
```

## Input Arguments
| Name | Type | Description |
|------|------|--------------|
| `scenario` | *Scenario object* | Scenario object |

## Name-Value Arguments
| Name | Type | Description |
|------|------|--------------|
| `Problem_type` | *"Lf" \| "Uf"* | Type of problem, either "Lf" for load flattening or "Uf" for user-friendly |
| `N_c` | *positive integer* | Number of chargers |
| `N_ev` | *nonnegative integer* | Number of EVs |
| `N_g` | *positive integer* | Number of groups (for analysis purpose) |
| `T` | *positive integer* | Number of time slots comprising a scenario |
| `Delta` | *positive scalar* | Length of time slot [minutes] |
| `P_max` | *nonnegative scalar* | Maximum aggregate charging power |
| `P_min` | *nonpositive scalar* | Minimum aggregate EV load (i.e., -(maximum aggregate discharging power)) |
| `D` | *T×1 column vector* | Base load profile [kW] (required for load flattening problem) |
| `C` | *T×1 column vector* | Electricity price profile [KRW] (required for user-friendly problem) |
| `EVs` | *1×N_ev EV array* | Array of EV objects |
| `L` | *(N_c+1)×(N_c+1) symmetric Metzler matrix with zero row sum* | Graph Laplacian describing topology of the aggregator and chargers (for load flattening problem, undirected, index N_c+1 corresponds to the aggregatgor) |
| `W` | *N_c×N_c nonnegative symmetric stochastic matrix* | Doubly stochastic matrix describing topology of the chargers (for user-friendly problem, undirected) |

## Output Arguments
| Name | Type | Description |
|------|------|--------------|
| `scenario` | *Scenario object* | Scenario object with modified property values |
