Hello! Let's say your house is connected to the local distribution grid, and you also have a PV-system on your house that is connected to the grid (no storage): How does the equipment in your house "use" the power from the PV module, and not "from" the grid? Everything is connected, right? If you have a power system with one power plant and a transmission line of say 100 miles to the consumer, you will have losses in the line. If you add a power plant 1 mile from the consumer in the same system, you will have less losses(?) But how does the consumer's equipment "choose" were to take the energy from? If you have less losses the current from the first power plant must be smaller. Anyone?
