As a contributor I would like to include varying electrical prices in place a single value #1679

In place of a fixed electrical pricing, adding in the varying electrical prices to reflect the Electricity costs. This also needs to have a provision when only data for a single value is available. Thus the config file needs to include a variable to do detailed electricity costs in place of a single one.

OR, electrical pricing is a schedule... an array with a price for each hour of the year. And have the data-helper create a version with all elements set to the single value?

@BhargavaKrishnaSreepathi I agree with daren that it could be an schedule. However it depends on how exact you want it to do:

  1. it is just ask the user off peak and on-peak tariffs. so just two variables.
  2. it consist into creating a schedule (but this has to be done manually every hour of a day).
  3. you connect to a certain webservices providing market prices.
  4. you define an equation that models those prices.

at the end, the option/model you select can be activated with a Flag in the config file, indicating, whether using fixed, prices or any other more detailed pricing scheeme

My current necessity is to use the electricity prices for every given hour as available in Singapore market. So the way I employed is create an excel sheet with the hourly cost details for the entire year and added to our database. I also added a config flag for detailed-electrical-pricing, which uses the database added. If the flag is false, it creates an array with electricity prices, by repeating the value we have in the LCA database (numpy.ones(8760) * electricity_price.

This setup can also further be extended based on the offpeak and peak tariffs, but currently I am not looking into them. The framework of creating an array either by importing the data or by creating (using the same value), should be good enough for handling offpeak/peak tariff scenario too.
