Abstract
- • The active and reactive power coordinated dispatching is decoupled to obtain the dispatching scheme rapidly. • The reactive power optimization model is established to adjust transformer tap and change capacitor output capacity. • Active power dispatching model of active distribution network is set considering network reconfiguration. • The DMA is used to solve the model, among which PSO is embedded to deal with the sequential coupling problem. • The voltage quality can be improved and DTC grid loss can be reduced effectively just by several equipment adjustments. The operation and dispatching pressure of active distribution network is gradually increasing with the integration of distributed generators into urban distribution network unevenly. It is necessary to carry out research on active and reactive power coordinated dispatching. In order to obtain the coordinated dispatching scheme rapidly, the active and reactive power coordinated dispatching is decoupled in this paper. Reactive power optimization and active power dispatching are carried out respectively. The final coordination dispatching scheme is formulated through the cross iteration of active power dispatching and reactive power optimization. Firstly, the reactive power optimization model is set by mainly considering adjusting transformer tap and changing capacitor output capacity. The model is solved by a two-stage method to obtain the dynamic dispatching scheme. Secondly, active power dispatching model of active distribution network is set considering network reconfiguration. To obtain the solution quickly, the discrete monkey algorithm is used to solve the model, among which particle swarm optimization algorithm is used in the climb process to solve the sequential coupling problem of switch state variables. Finally, the node voltage quality can be effectively improved and grid loss of distribution transformer cluster can be significantly reduced by a few of adjustments of transformer taps, shunt capacitors and switch. The practicability of dynamic coordination dispatching method is proved. [ABSTRACT FROM AUTHOR]
