作为能耗第三的交通行业,由于用能需求的增长以及疫情的影响,能源结构面临转型升级。光伏与储能技术的发展,为其在交通行业的应用提供了可靠支撑。该研究提出了一种考虑储能动态特性应用于高速公路场景的光储协调配置方案。首先,基于储能的物理放电特性,建立了储能寿命模型与等效寿命损耗成本。然后,提出了协同配置方案的优化模型,将等效寿命损耗成本考虑进了优化模型中。最后,使用一种改进的量子粒子群算法,以新疆地区高速公路场景作为案例进行仿真,验证了模型的可行性,对于可靠性要求较高的场景具有参考价值。

As the third energy consuming industry,the transportation industry is facing the transformation and upgrading of energy structure due to the growth of energy consumption demand and the impact of the epidemic.The development of photovoltaic and energy storage technology provides reliable support for its application in the transportation industry. In this study,a co-configuration operation scheme of pv and energy storage in highway energy consumption scenario consideringthe dynamic characteristics of energy storageis proposed. Firstly,the energy storage life model and equivalent life loss cost are established based on the physical discharge characteristics of energy storage. Then, the optimization model of the cooperative configuration scheme is proposed,and the equivalent life loss cost is taken into account. Finally,an improved quantum particle swarm optimization(QPSO)algorithm is used to verify the feasibility of the model by taking xinjiang expressway scenario as a case,which is of great reference value for scenarios with high reliability requirements.
