what is the effect of adding load_shedding on the network ?

Hi ,

what is the effect of  adding load_shedding on the network ?

i have understood that we add load shedding to solve infeasibility solution ,

• could some explain in details what does load shedding do exactly ?
• what does the effect on lines ?Does it has effect on lines congestion ?
  

i have read some articles but i am still facing problem to understand it correctly

Thanks for any help .

Hi,

in PyPSA-Eur load shedding is implemented as a generator at each node
with very high marginal cost. The marginal cost is set so high that it
will only ever be used if no other combination of technologies can
supply the demand. When this generator is used, it usually means
something is off. You could interpret it as load not supplied. As it
interacts with the nodal imbalance, it could also affect line congestion.

Best wishes,

Fabian N

thanks for ur explanation  ,when  i add load shedding , it means may be add generators if required and may be not .it depends , right?

but how does it effect line congestion ?

i mean , in case of adding load shedding and increasing demand in each modelling ,what should i expect for line congestion ?
