摘要:

在综合考虑调峰补偿收益和节煤收益情况下,提出了计及最小运行成本的储能参与电网辅助调峰协调优化控制方法。以系统净收益最大为目标,建立了储能参与电网辅助调峰的容量优化配置模型,分别利用人工蜂群(ABC)算法和粒子群优化(PSO)算法对模型进行求解,得到最优储能容量配置。以系统运行成本最小为目标函数,建立了储能参与电网辅助调峰的优化控制模型,协调优化后的系统弃风率降低为1.078 8%,系统总运行成本降到1 401.08万元。最后,通过某省电网实际运行数据仿真分析验证了所提方法的有效性和正确性。

Abstract:

From the point of view of peak shaving compensation and coal saving,a capacity configuration and coordinated control method of energy storage participating in power grid auxiliary peak shaving based on the minimum operating cost is proposed.Aiming at maximizing the net profit of the system,the optimal capacity configuration model of energy storage participating in auxiliary peak shaving is established.ABC and PSO algorithms are respectively used to solve the model for the optimal capacity configuration of energy storage systems.With the minimum operating cost of the system as the objective function,an optimized control model for energy storage to participate in the auxiliary peak shaving of the grid is established.After coordination and optimization,the system wind abandonment rate is reduced to 1.078 8%,and the total system operation cost has been reduced to 1 401.08 million yuan.The validity and correctness of the method are verified by simulation analysis of the actual operation data of a power grid in a province.

Key words: energy storage system, auxiliary peak shaving, capacity optimization configuration, coordinated optimization
