Government subsidy levels both influence and are influenced by energy storage operators' engagement and power system transformation. Energy storage operators become proactive when their participation profit coefficient exceeds a critical threshold.
With the gradual increase of energy storage equipment in the power grid, the situation of system frequency drop will become more and more serious. In this case, energy storage equipment integrated into the grid also needs to play the role of assisting conventional thermal power units to participate in the system frequency regulation.
The government's incentive funds, including policy publicity and fiscal subsidies designed to encourage investment and industrial growth among energy storage operators, are insufficient compared to the national fiscal subsidies granted to the energy storage industry. Specifically, the subsidy coefficient S 1 <a D.
Additionally, the energy storage capacity subsidy is a one-time payment of 200 CNY/kW, while there are ongoing subsidies for charging and discharging (0.5 CNY/kWh) and for peak-valley arbitrage (0.7 CNY/kWh). The energy storage system is assumed to operate for 300 days annually, with two charge-discharge cycles per day.
Assuming that the bid FR power of each ES unit is its rated power in the regional power grid.
The subsidy period lasts for 3 years following the completion of the energy storage project. Furthermore, depreciation and maintenance costs for the energy storage system are estimated to be 4 % of the initial system investment cost. The relevant data are summarized and presented in Supplementary Information Table D.1.1.
