小型光伏发电装机容量的增加和电动汽车需求的增长为不平衡的配电网络带来了运营挑战。为了保证配电网的安全，在考虑电动汽车并网的情况下，提出了确定光伏发电可调度极限的两阶段优化问题。与以下方面有关的不确定性：a)到达和离开时的收费状况；B)电动汽车的能量和动力容量；C)考虑了最大预测太阳辐射和需求。该优化问题采用列约束生成方法求解。采用改进的IEEE 13总线测试系统对所提框架的有效性进行了评价。
The increase in the installed capacity of small-scale photovoltaic generation and the growing demand for electric vehicles introduce operational challenges for the unbalanced distribution networks. This paper presents a two-stage optimization problem to determine the dispatchability limits of photovoltaic generation considering the electric vehicles’ interconnection to ensure the security of the distribution network. The uncertainty associated with a) the state of charge at arrival and departure times; b) the energy and power capacity of electric vehicles; c) the maximum forecasted solar radiation and demand were considered. The proposed optimization problem is solved using the column-and-constraint-generation approach. A modified IEEE 13-bus test system is used to evaluate the effectiveness of the proposed framework.
