摘要:

随着电动公交数量的迅猛增加以及光伏能源的大力发展,建设光储充电站成为了更好的方案。针对电动公交大规模接入的同时提高光伏储能的回报率和减少充电站的成本问题,建立了以公交充电成本最低和光储联合收益最高为目标的光储电动公交充电站优化模型,引入交替方向乘子算法(ADMM)将集中优化问题转换为以公交车和光储为主体的子优化问题求解,减少了计算复杂度。通过真实数据进行仿真,结果表明所提模型在减少充电成本的同时可以有效地最大化光储的回报率,相比集中式优化算法收敛更加迅速。

Abstract:

With the rapid increase of the number of electric public transport and the vigorous development of photovoltaic energy,the construction of optical storage charging station has become a better solution.Aiming at the problem of improving the return rate of photovoltaic energy storage and reducing the cost of charging stations while large-scale access of electric bus,an optimized model of optical storage electric bus charging station with the lowest cost and the highest combined benefit of light storage is established.The algorithm of alternating direction multiplier method (ADMM) is introduced to transform the centralized optimization problem into the sub-optimization problem based on the bus and the optical storage,which reduces the computational complexity.Simulation by real data shows that the proposed model can effectively maximize the return of photovoltaic energy storage while reducing charging costs,and converges more quickly than centralized optimization algorithms.

Key words: electric bus, photovoltaic electric bus charging stations, alternating direction multiplier method (ADMM), distributed algorithms
