Peak-valley electricity price difference energy storage system

In terms of economic optimization, the core economic indicators for energy storage configuration depend on three main variables: 1) Peak-valley price difference (δp): the larger the difference, the greater the arbitrage potential for energy storage; 2) Limit electricity rate (γ): for every 1% increase in limit rate, project revenue decreases by approximately 0.02 RMB/kWh; 3) The cost of the energy storage system itself.
