The active/reactive powers in line from bus 3 to bus 4 decrease

The voltage at bus 2 is higher than the votage at bus 1

The voltage at bus 2 increases

The line losses in the system decrease

The operating voltage at bus 4 is higher than the voltage at bus 3

The operating voltage at bus 3 is lower than the voltage at bus 2

The feeder is part of the transmission network

The nominal voltage value is 400 V

The operating voltage at bus 4 is higher than the voltage at bus 3

The operating voltage at bus 3 is lower than the voltage at bus 2

The feeder is part of the transmission network

The nominal voltage value is 400 V

The active/reactive powers in line from bus 3 to bus 4 decrease

The voltage at bus 2 is higher than the votage at bus 1

The voltage at bus 2 increases

The line losses in the system decrease

Increase electricity imports from neighboring countries

Store excess electricity using pumped-storage hydro stations

Turn off one or several nuclear power plants

Activate demand response programs to reduce consumption

Decrease electricity exports to neighboring countries

Increase generation from gas power plants

Reduced line losses

Reduced greenhouse gases emissions

Improving predictability of generation / energy usages

Defferment of grid reinforcement

Decrease the load

Increase the voltage

Change the grid topology (open/close lines)

Increase the power generation

The topology

The frequency

The losses

The voltage

The electricity demand is quite inelastic relatively to prices variations in real time

Modern power system (generation, networks, retail)  are organized as monopolies

Electricity cannot be stored at a large scale

It is impossible to "track electrons" from the generation to the point of delivery
