摘要

结合储能寿命等效全循环模型,提出考虑储能循环里程成本的风-火-储协调优化调度方法。首先,结合全寿命等效全循环次数计算模型,进一步完善储能装置在不同充放电深度的循环里程中的寿命损耗评估模型;然后,在精准核算储能循环里程成本的基础上,构建考虑储能运行成本、火电机组运行成本、弃风损失等因素的风-火-储协调优化调度模型;最后,通过算例分析验证了所提出方法的正确性与有效性,并与传统的以度电成本结算储能运行成本的调度方法相比,有效避免低估低荷电状态下放电对储能寿命的影响,保障了储能使用寿命。

Abstract

This paper proposes a wind-fire-storage coordinated optimal scheduling method considering the cycle mileage cost of energy storage by combining the full-life equivalent full-cycle model of energy storage. Firstly, in conjnnction with the calculation model of the full cycle number of the entire life, the life loss evaluation model of the energy storage device in the cycle mileage of different charge and discharge depths is further enhanced. Then, on the basis of accurately calculating the cost of energy storage cycle mileage, we constructed a wind-fire-storage coordinated optimization scheduling model considering factors such as energy storage operating cost, thermal power unit operating cost, and wind curtailment loss is constructed. Finally, the correctness and effectiveness of the proposed method are verified through example analysis, and compared with the traditional scheduling method of settling the operating cost of energy storage by kWh, this approach effectively avoided the negative impact of discharging under low charge on energy storage life, thereby ensuring the service life of energy storage system.
