| 摘 要： | 储能设备成本不断降低,为配电网的削峰填谷和经济运行提供了新的思路。首先研究了储能设备的充放电模型和充放电策略,在此基础上建立了含储能电力系统的多时段优化运行模型,并利用稀疏自动微分技术减少代码编写工作量、通过储能电量约束缩减降低微分计算量的方式,有效地提升了模型求解的可行性与高效性。最后,通过某实际配电网储能示范工程的算例仿真,验证了模型的准确性、算法的高效性与策略的可行性。

| Abstract: | The cost of energy storage equipment is decreasing,which provides a new idea for load shifting and economic operation of distribution network.This paper studied the charge/discharge model and strategy of energy storage,and constructed a multi period optimal operation strategy model of distribution network with energy storage.Sparse coding automatic differentiation technology was applied to reduce coding workload,and constraint reduction of energy storage was proposed to reduce differential calculation,which enhanced the feasibility and efficiency of the model solving.Finally,the simulation results of an actual distribution network with energy storage demonstrated the accuracy of the proposed model,the efficiency of the proposed algorithm and the feasibility of the proposed solving method. |
