Free QuoteTo address these challenges, the future power system must have sufficient flexibility. The Energy Storage System (ESS) is an important flexible resource in the new generation of power systems, which offers an efficient means to address the high randomness, fluctuation, and uncertainty of grid power.
Trackside energy storage systems (TESSs) can be an alternative solution for the creation of new substations. A TESS limits contact line voltage drops and smooths the power absorbed during peak traffic. Thus, the efficiency of the power system can be increased while limiting costs and the environmental impact.
To address the issues of limited Energy Storage System (ESS) locations and the flexibility unevenly distributed in the large-scale power grid planning, this paper introduces the Dynamic Programming (DP) theory into flexibility planning, and proposes a DP-based ESS siting and sizing method.
Energy and power capacity of candidate storage plants are unconstrained and optimized by the model from the perspective of the grid, such that the model may build storage of any duration and size in each load zone.
By combining the state transition equation and the DP basic equation, the proposed method culminates in the energy storage allocation dynamic programming model, which determines the optimal locations, capacities, and rated powers of ESSs, along with the construction cost.
First, our results suggest to industry and grid planners that the cost-effective duration for storage is closely tied to the grid's generation mix. Solar-dominant grids tend to need 6-to-8-h storage while wind-dominant grids have a greater need for 10-to-20-h storage.
