Can a joint planning and reconstruction strategy enhance power supply capacity?
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.
Does a network and energy storage Joint Planning and reconstruction strategy achieve cost minimization?
Additionally, the network and energy storage joint planning and reconstruction strategy proposed in this study achieves cost minimization under the constraint of limited resources and simultaneously enhanced both capacities. The strategy provides feasible solutions for power grid planning in actual applications.
Does network and energy storage Joint Planning and reconstruction account for source-load uncertainty?
To achieve this, a network and energy storage joint planning and reconstruction strategy that accounts for source-load uncertainty is proposed. The main conclusions are as follows:
However, most existing studies on the coordinated planning of energy storage and transmission lines are based on static planning. They implement a one-time planning process from the current state to the target year, failing to consider the gradual growth of load demand and renewable energy capacity.
Effectiveness of Joint Planning and Reconstruction Strategy: The proposed joint planning and reconstruction strategy effectively facilitates the optimal allocation of distributed generation and energy storage systems while reconfiguring the distribution network topology.
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.
