储能火电联合调频的容量优化配置研究

  目的  为储能火电联合调频项目合理配置储能容量，建立联合调频的收益模型，提供储能功率选择的依据。  方法  基于广东某电厂机组的历史运行数据和市场出清价格，对机组和储能联合调频进行仿真计算，分析储能功率选择对联合调频性能和收益的影响。  结果  仿真结果表明:储能系统通过提升机组的调频性能和增加调频里程，大幅提升调频收益，且随着储能功率的增加，调频收益逐渐增加后趋于稳定；受机组性能差异和运行状况的影响，储能对调频性能和调频收益提升的程度不同。  结论  证实通过仿真计算确定储能容量是合理可行的，可为后续联合调频项目中储能容量优化提供参考。

Research on Capacity Optimization of Generator-storage Combined Frequency Regulation System

  Introduction   The paper aims to establish the profit model of generator-storage combined frequency regulation system and give the basis for battery storage power selection to determine the optimal capacity of battery storage.   Method  Based on the historical operation data of a power plant and market price in Guangdong Province， we simulated the participation of battery storage in frequency regulation and analyzed the influence of battery storage power selection on the performance and income of combined frequency regulation.  Result  The simulation results show that the battery storage system can greatly improve the frequency regulation income by enhancing the performance of the power unit and the mileage. With the increase of the battery storage power， the frequency regulation income gradually increases and then tends to be stable.  Conclusion  The impact of battery storage power on the performance and income is different due to the unit performance differences and operating conditions. This work provides that it is reasonable and feasible to determine the battery storage capacity through simulation calculation， which can provide reference for the optimization of battery storage capacity in subsequent projects.
