Proposing a network and energy storage joint planning and reconstruction strategy: This paper innovatively proposes a bi-level optimization model that combines network structure optimization with energy storage system configuration, achieving a simultaneous improvement of power supply capacity and renewable energy acceptance capacity.
The distribution network is assumed to operate under steady-state conditions, with no consideration given to the impact of extreme conditions. The charging and discharging efficiency of the energy storage system is modeled using a simplified approach, without accounting for complex behaviors.
Although it helps mitigate the uncertainty of distributed generation output, it does not directly increase the maximum power supply capacity of the distribution network.
Based on the data provided by the upper-level planning layer, which are transmitted to the lower-level for calculation, the distribution network undergoes reconstruction at the lower level. The power supply capacity and the renewable energy acceptance capacity for distributed generation are then calculated using Equations (24) and (25).
Addressing this strong coupling while enhancing both capacities presents a critical challenge in modern distribution network development. This study introduces an innovative joint planning and reconstruction strategy for network and energy storage, designed to simultaneously enhance power supply capacity and renewable energy acceptance capacity.
