Abstract

The invention discloses a method and a system for active distribution network energy storage configuration. The method comprises steps: according to the target chance constraint risk cost for active distribution network power demands, the target chance constraint risk cost for active distribution network flexibility demands, the output cost for active distribution network generator units and the loss cost of an active distribution network energy storage unit in the whole operation cycle, the energy storage capacity optimization target value of the active distribution network energy storage unit is determined; and when the active distribution network is judged to meet preset power balance constraints, node voltage constraints and branch current constraints, the capacity of the active distribution network energy storage unit is configured according to the minimum value of the energy storage capacity optimization target value of the active distribution network energy storage unit. The active distribution network power demands and the flexibility demands are considered comprehensively, reasonable energy storage configuration is carried out on the active distribution network, the consumption capacity of renewable energy by the power grid can be effectively improved, the electric energy quality is improved, and the operation stability of the power system is improved.

Description

technical field

[0001] The invention relates to the technical field of power grids, in particular to an active distribution network energy storage configuration method and system. Background technique

[0002] With the development of renewable energy technology, a high proportion of renewable energy power generation has become a future power system scenario that is widely concerned around the world. As typical high-proportion renewable power generation resources, wind power and photovoltaic power generation have the characteristics of randomness and volatility due to their dependence on natural conditions. Especially in the active distribution network (ADN), the volatility and uncertainty of high-penetration renewable power generation resources have brought great challenges to the operation and scheduling of the active distribution network. With its fast power adjustment capability, the energy storage unit can not only improve the characteristics of renewable energy power g...
