In addition to reducing the peak-valley difference of transformer stations, additional centralised energy storages will be allocated to realise peak-valley price arbitrage when the investment of centralised energy storage units is not less than 1400 yuan/kWh and no
The use of BESS to achieve energy balancing can reduce the peak-to-valley load difference and effectively relieve the peak regulation pressure of the grid [10]. Lai et al. [11] proposed a method that combines the dynamic thermal rating system with BESS to reduce system dispatch, load curtailment, and wind curtailment costs.

Accompanied by energy structure transformation and the depletion of fossil fuels, large-scale distributed power sources and electric vehicles are accessed to distribution network that result in the load peak-valley gap increasing. Energy storage system (ESS) possessed the characteristics such as quick response, precise control and energy bidirectional flow.
With the increase of peak-valley difference in China''s power grid and the increase of the proportion of new energy access, the role of energy storage plants with the function of "peak-shaving and valley-filling" is becoming more and more important in the power system. In this paper, we propose a model to evaluate the cost per kWh and revenue per kWh of
