Flexible distribution network: definition, configuration, operation, and pilot project

Analysis of Distributed Generation Accommodation in Flexible Distribution Networks

“…The definition of the DG-load accommodation ratio is consistent with the matching degree, which reflects the overall DG-load power balance. The concept of DG-load accommodation ratio is similar to the "substation capacity-load ratio" (Xiao et al, 2018a), which is a classical index for distribution network planning, and also neglects the network operational constraints.…”

Evaluation of an Optimal Radial-Loop Configuration for a Distribution Network With PV Systems to Minimize Power Loss

“…However, these concerns have recently been addressed due to the development of optical communication technology and distribution automation systems [26]- [29]. Thus, several papers have focused on loop configurations as useful configurations for a future power system because this configuration can contribute to mitigating voltage violations and reducing power losses by balancing the power flow in feeders with distributed generators (DGs) [30]- [47]. In [30]- [38], new devices, such as a unified power flow controller or a loop power flow controller, were used for loop operations.…”

“…In [30]- [38], new devices, such as a unified power flow controller or a loop power flow controller, were used for loop operations. In [30], the contribution from reducing voltage fluctuations was evaluated in a distribution network with DGs. The reconfiguration of a loop operation was discussed to maximize the hosting capacity of DGs [36].…”

Flexibility evaluation of active distribution networks considering probabilistic characteristics of uncertain variables

“…Ji et al [17] evaluated the flexibility of SOP integration by the maximum RE hosting capacity. Xiao et al [18] defined the flexible distribution network and presented the normal operation mode, N − 1 mode, and related analysis methods. In the existing studies, only the volatility of REOP and load demand are investigated, but the uncertainty from forecasting error is not considered.…”
