The Cence all-in-one DC (Direct Current) distribution system supplies low and high-voltage DC power. We manufacture Class 2 (low-voltage) and Class 4 (fault managed power) products.
DC distribution systemOptimal dispatchEconomic dispatch coordinates the generation across the distribution network while minimizing the overall generational cost. Optimal dispatch is a global optimization problem and, thus, conventionally carried out by a supervisory controller. However, reliability concerns ...
DC distribution network Power flow calculation Multiple types of flexible equipment Bipolar Nomenclature Variables IPpi Load current of constant power load of node i Vpnuj, Vnunj, Vpnj Positive, negative, and bipolar voltages of node j Vpnuk, Vnunk, Vpnk Positive, negative, and bipolar voltages...
It reveals a high potential to solve location problems in DC distribution systems. This paper proposes a depth learning based fault location for DC distribution networks. First, a DC distribution network with radiant topology is modelled, and faults are added with different parameters to simulate ...
Passive filter topologies used at the output of the customer-end inverter in a low-voltage DC-distribution (LVDC) network are compared. The comparison of filter topologies is based on the requirements set for the voltage quality and issues such as the physical size of the filter, losses, the...

After installation, DC operations now run unattended, with an integrated management platform combining power supply, distribution, temperature control, Information Technology (IT), and network subsystems. AI technologies are also used to ensure that the DC provides remote visualization and automatic Operat...
Both power electronic equipment and conventional control devices, such as tie switches, coexist in a hybrid AC/DC distribution network, and the coordination optimisation of these control devices can eliminate the risks caused by high-penetration renewable energy generation (REG) integration. Here, the...
