I'm trying to design a basic electrical system of a large island and I'm having trouble deciding for the site locations. The existing grid of the island has a diesel plant located near the town but I thought that it is a bad idea to have a plant near the load as itis dangerous. I cannot see a nearby distribution substation.
Is it possible that the distribution substation is located far from the plant? What's the purpose of putting it far from the plant if the load is nearby?
The towns are close together on the island, so I was thinking of having the generation close to the distribution substation to save cost on building transmission lines and towers.
This is snipet of the map:
The yellow areas are the location of the loads. The G symbol is the generation plant. It is connected to the generation substation. The blue and red circles are the distribution substations.
I'm not sure if I'm doing this right at all. My considerations for the location of the plant is that the area should be flat and available. As I chose a diesel plant which requires minimum space, I decided to have it a little closer to the load to save on cost on building transmission towers and lines.
I'm totally new to this so I'm hoping to be corrected on wrong assumptions.
