Abstract:

Active distribution networks often face power fluctuation due to intermittent and stochastic characteristics of distributed generations (DGs), as well as uncertainties associated with the spatial and temporal distributions of charge and discharge of electric vehicles (EVs). Energy storage systems (ESS) provide an effective mean to mitigate the power fluctuation in such distribution networks. This paper analyzes the connotation of active distribution networks and the origin of the power fluctuation, and reviews the status of ESS for mitigating the power fluctuation. This includes optimal configuration and control of ESS, and dispatch and control strategy of electric vehicles. The results indicate that the power fluctuation could be successfully mitigated through selection, optimal configuration, and effective control of ESS.

Key words: active distribution networks, power fluctuation, energy storage system, fluctuation mitigation
