Expectations both on electricity distribution techniques and the distribution business are growing. The utilization of the DC low voltage distribution opens new possibilities for network development. For example, with the same voltage drop and the same 3~cable 16 times more power can be transmitted with a 1.5 kV DC-system than with 0.4 kV AC system.
The cost of the traditional HVDC system is high because of the need for filters, capacitors and other auxiliary equipment. The traditional HVDC system is designed for the transmission of large amounts of energy measured in hundred of megawatts. This system is not economical less for than 20 MW loads.
The price must be based on few data, as rated power, transmission distance, type of transmission and voltage level in the AC networks where the converters are going to be connected. When the voltage is lower the price goes down, so in distribution networks the total cost is lower than in the transmission ones.
Nowadays electricity distribution networks construct mainly of the three-phase AC systems. Consumer voltage in traditional distribution system is 230/400 V and the nominal frequency is 50 Hz. The utilization of the 1 kV distribution systems takes full advantage of LVD directives low voltage AC-system definition.
Although AC voltage rating is today used in its full capacity the DC voltage is still unexploited in distribution systems. Component prices of power electronics have constantly been decreasing in the last decade allowing power electronic devices to be used in greater number of applications. DC-distribution enables the improvement of the customers electricity quality beyond todays level with lower costs compared to AC systems.
The economical benefit can be achieved through the better transmission capacity of low voltage DC-distribution compared to low voltage AC-distribution. With the same costs of losses smaller conductors compared to AC distribution can be used. In addition to that there is no need for public 400 V low voltage distribution. The DC network could also be a good solution for connecting small scale DG to the distribution network.
