I really wish a simulated version with very granular transmission and distribution capacity for different type of producers and consumers, from large plants to individual houses to community solar or agrivoltaics could exist. This might be very helpful in understanding how to correctly allocate the infrastructure to enable distributed production at the right place. What kind of reversible flow is possible ? What types of electrical equipment is needed etc. I feel finally we are at a place where grid cost might be much higher than solar and batteries when amortized over 20-25 years.
