Economic Analysis of Transactions in the Energy Storage Power Market: A Life-Cycle Cost Approach

Aiming at the impact of energy storage investment on production cost, market transaction and charge discharge efficiency storage, a research model economic boundary taking into account whole life cycle cost was proposed. Firstly, peak-valley filling time division method based equal capacity is proposed, which effectively improves accuracy ES should scene switch. On this basis, control strategy “off-time reuse” proposed to give full play function “one standby multi-purpose” utilization rate benefits. Secondly, an life-cycle evolution constructed solved by improved genetic algorithm. Finally, simulation results show that compared with mono-peak control, UTILIZATION increased 16.25% recovery shortened 1.17 years strategy. Compared fixed method, “peak clipping valley filling” period 1.75 years. In 2022, critical value 0.76 yuan/kWh for charge-discharge 0.8 yuan/kWh, error up 5.26%.
