Abstract—We investigate the profitability and risk of energy storage arbitrage in electricity markets under price uncertainty, exploring both robust and chance-constrained optimization ap-proaches. . Peak-valley electricity price differentials remain the core revenue driver for industrial energy storage systems. By charging during off-peak periods (low rates) and discharging during peak hours (high rates), businesses achieve direct cost savings. Key Considerations: Cost Reduction: Lithium. . The energy storage system not only means storing energy and releasing it when needed, but it can also be profitable. An energy storage power station can even achieve an annual income of between 5 million and 10 million. In addition, industrial and commercial EES participates in pe in the integration of intermittent renewa al optimized operation strategy of DES. .
