Coordinated Optimal Network Reconfiguration and Voltage Regulator/DER Control for Unbalanced Distribution Systems

Reducing the active power curtailment of distributed generation based on soft open points in unbalanced distribution networks

“…S i, ϕ, DG is the phase-φ capacity of the DG converter. Constraint (5) indicates that the active power of DG should be less than the predicted value. Constraints (6) and 7are the reactive power and capacity limits of DG, respectively.…”

“…Conventional voltage regulation measures of distribution networks include the utilisation of on‐load tap changers, capacitor banks, tie switches, and other primary equipment [4, 5]. However, meeting the requirements of rapid voltage regulation is difficult because of the slow response of this equipment.…”

Co‐optimising distribution network adequacy and security by simultaneous utilisation of network reconfiguration and distributed energy resources

“…Network reconfiguration is represented as the action of changing the topological structure of feeders by intelligently changing the status of tie and sectionalising switches from open to close and vice versa, without altering the radial structure of the network. The reconfiguration must be done for a number of reasons, including loss reduction [6,7], voltage profile improvement [8,9], reliability enhancement [10,11], etc. With active DERs in the network, reconfiguration will become more complex especially if security is a concern.…”

Dynamic Robust Reconfiguration of Distribution Network with Low-wind-speed Wind Turbine Integrated

“…The main difference is that the dynamic distribution network reconfiguration (DDNR) takes into consideration the time-varying nature of loads [1]. Some researches have been done on static distribution network reconfiguration (SDNR) from the perspective of strategy improvement and solving algorithm [2][3][4][5][6][7][8][9]. However, with the loads of distribution network varying, SDNR cannot guarantee the optimal operation economy of the network since only a single time section is considered.…”
