| 摘 要： | 随着电动汽车渗透率的增加，电动汽车的无序充电会给区域配电网的运行带来很大压力。为了减小电动汽车负荷对电网的影响，提出了一种电动汽车智能充电的调度策略。在分时电价的基础上，将充电成本最小化和负荷方差最小化作为目标函数，考虑了充电机最大充电功率限制等约束条件，建立了电动汽车集中充电的多目标优化调度模型。采用了非支配排序遗传算法(NSGA-II)对优化模型进行求解，通过Matlab算例的计算结果验证了该策略的可行性和有效性。分析了不同数量电动汽车和不同时间窗口的取值对优化结果的影响，并据此给出了相关建议。

| Abstract: | There is no common accepted way for calculating the valve power loss of modular multilevel converter (MMC). Valve power loss estimation based on analytical calculation is inaccurate to address the switching power loss and valve power loss estimation based on detailed electro-magnetic simulation is of low speed. To solve this problem, a method of valve power loss estimation based on the detailed equivalent simulation model of MMC is proposed. Results of valve power loss analysis of 201-level 500MW MMC operating at 50Hz~1000Hz are presented. It is seen that the valve power loss of a MMC increased by 12, 40 and 93 % under 200Hz, 500Hz and 1000Hz operating frequency. The article concludes that in a device with solated inner AC system, MMC operating at higher frequency will be more competitive than typical 50Hz/60Hz MMC with moderate increase of operating power loss and significant reduction of the size of the AC components. |
