PowerPlant

This project is an implementation of the challenge made by Engie GEM team.

Pre requirements

The project is using .NET 8 so, if you use Visual Studio or Visual Studio Code, make sure that :

• .NET 8 SDK is installed
• Visual Studio is up-to-date if you use it

Start the project

To start the project, you can either :

• Use Docker
• Use dotnet CLI command
• Use Visual Studio

Use Docker

In the root of the solution, build the docker image by running the following command :

docker build -t power-plant-api -f Dockerfile .

And then run the container with the following command :

docker run -d -p 8888:8888 --name power-plant-api power-plant-api

Use CLI command

Head in the api folder of the project and run it with the following commands :

cd .\PowerPlantCC.Api\
dotnet run

Use Visual studio

Open PowerPlantCC.sln solution file and run the solution.

Project feature

The project exposes the following endpoint :

POST http://localhost:8888/productionplan

The purpose of this endpoint is to calculate the usage of given powerplants to reach a specific given power load in the most cost effective way by taking into account different parameters such as fuels costs, CO2 production cost and wind.

It expects a body with the following structure :

{
  "load": 0.0,
  "fuels":{
    "gas(euro/MWh)": 0.0,
    "kerosine(euro/MWh)": 0.0,
    "co2(euro/ton)": 0.0,
    "wind(%)": 0.0
  },
  "powerplants": [
    {
      "name": "string",
      "type": "string",
      "efficiency": 0.0,
      "pmin": 0,
      "pmax": 0
    }
  ]
}

The payload contains 3 types of data:

• load: The load is the amount of energy (MWh) that need to be generated during one hour.
• fuels: based on the cost of the fuels of each powerplant, the merit-order can be determined which is the starting point for deciding which powerplants should be switched on and how much power they will deliver. Wind-turbine are either switched-on, and in that case generate a certain amount of energy depending on the % of wind, or can be switched off.
  • gas(euro/MWh): the price of gas per MWh. Thus if gas is at 6 euro/MWh and if the efficiency of the powerplant is 50% (i.e. 2 units of gas will generate one unit of electricity), the cost of generating 1 MWh is 12 euro.
  • kerosine(euro/Mwh): the price of kerosine per MWh.
  • co2(euro/ton): the price of emission allowances (optionally to be taken into account).
  • wind(%): percentage of wind. Example: if there is on average 25% wind during an hour, a wind-turbine with a Pmax of 4 MW will generate 1MWh of energy.
• powerplants: describes the powerplants at disposal to generate the demanded load. For each powerplant is specified:
  • name:
  • type: gasfired, turbojet or windturbine.
  • efficiency: the efficiency at which they convert a MWh of fuel into a MWh of electrical energy. Wind-turbines do not consume 'fuel' and thus are considered to generate power at zero price.
  • pmax: the maximum amount of power the powerplant can generate.
  • pmin: the minimum amount of power the powerplant generates when switched on.

And returns the power produced by each given powerplants with the following structure :

[
    {
        "name": "string",
        "p": 0.0
    }
]
