I was trying to model a system which produces Hydrogen via electrolysis, from wind and solar generators. The capacity of the generators are fixed. The only Load is the Hydrogen demand. There is no electricity demand.
- Bus: 2 - electricity,hydrogen
- Carrier: 6
- Generator: 3 - wind,solar,sales
- Link: 1- electrolysis
- Load: 1- hydrogen demand
- Store: 1- hydrogen store
I want the excess electricity produced in the system to be sold at the market price:
How do i model this sale of electricity. The only solution i could come up with after going through the pypsa documentation was to model a gnerator as shown below:
n.add( "Generator", "sales", bus="electricity", p_max_pu=0, p_min_pu=-1, p_nom=22,#MW random value which is higher than total generation capacities marginal_cost=ts.prices, #spot market price carrier='prices' )
I got a negative objective function- which i assumed is due to the revenue obtained from the (generator)-sales of electricity.
a) How accurate is this way?
b) Is there any other way to model the above system?
