- Abstract:
- In order to provide voltage sag compensation in distribution network, a model to optimize the alloca�1Ftion of distributed energy storage system ( DESS) and a control strategy incorporating DESS and dynamic volt�1Fage restorer (DVR) was formulated and solved have been formulated and solved. In this paper, a double-layer DESS allocation model based on minimize the installation cost of DESS, voltage sag detection equipment and voltage sag of sensitive load was formulated to find optimal configuration of DESS. Then, the minimization cost of DVR, DESS and maximization of voltage for sensitive loads were achieved by joint compensation control model combining DESS and DVR. Moreover, the particle swarm optimization algorithm with random mutatio was employed to seek optimal solution of the proposed model. This approach was tested on the IEEE 33 bus system integrated with DESS and sensitive load. The results revealed that the optimal allocation model could re�1Fduce storage capacity, and dispatch model could successfully meet the demands when considering voltage sag and further reduce the investment of the compensation equipment.
