规模化电动汽车的普及显著加速了交通电气化转型，给配电网带来“峰上加峰”、电能质量劣化等挑战，加之电力和交通系统隶属于2个不同的运营主体，集中式优化实施困难。为此，提出1种基于等值映射的电力-交通非迭代协同优化方法。首先，构建含充电站功率的电力-交通解耦框架，将配电网最优运行模型转化为边界充电站功率的分段成本函数和所对应的等效约束集，从而使得电力-交通系统解耦单系统优化问题。其次，利用边界成本函数与节点电价的内在联系，提出含价格信号的电动汽车优化充电策略，缓解配电网重过载。最后，通过算例验证所提方法的有效性，表明有序充电策略可有效引导电动汽车充电行为，改善电压质量。

Abstract

The widespread adoption of electric vehicles (EVs) has significantly accelerated the electrical transition of transportation, which brings challenges to distribution network such as "peak-on-peak" demand and deterioration of power quality. Moreover, the power and traffic systems belong to two different operators, so it is difficult to perform centralized optimization. To address these issues, a novel non-iterative coordinated optimization method for power-traffic based on the equivalent mapping theory is proposed. First, a decoupled framework for power-traffic incorporating the power at charging stations is established, and the optimal operation model of distribution network is transformed into a piecewise cost function with boundary charging station power and the corresponding equivalent constraint sets, thereby achieving the decoupled and coordinated optimization of power-traffic systems. Second, by exploiting the intrinsic relationship between boundary cost functions and nodal electricity prices, an optimized charging strategy for EVs which incorporates price signals is put forward, so as to alleviate the overload issues in distribution network. Finally, the effectiveness of the proposed method is validated through a case study, and results also demonstrate that the orderly charging strategy can effectively guide the EV charging behavior and improve the voltage quality.
