摘要
近年来,极端天气对高速公路电网系统造成严重破坏,如何合理调配移动电源车是目前高速公路故障抢修中亟须解决的难题。因此,本文提出了一种极端天气下高速公路移动电源车的优化调度方法。首先,利用蒙特卡洛模拟方法,通过历史天气数据和实际线路参数,构建极端天气下覆冰载荷、风力载荷和绝缘子闪络的数学模型,得到输电线路脆弱性模型,进而确定整个系统的故障情况;其次,通过蒙特卡洛模拟方法和目标函数收敛条件,求出移动电源车的最优接入点,调度移动电源车提高系统弹性;最后,利用新疆某高速公路服务区自洽能源系统数据进行仿真分析。结果表明,相比于目前常用的移动电源车接入点固定不变的方法,本文提出的调度方法使恢复供电的负荷比例提高了12%,提升了移动电源车的工作效率和自洽能源系统的弹性性能。
Extreme weather in recent years has caused serious damage to the highway power grid system,how to reasonably deploy mobile power vehicles is the current highway fault repair in the urgent need to solve the problem.Therefore,this paper proposes an optimal scheduling method for mobile power vehicles on highways under extreme weather.Firstly,the Monte Carlo simulation method is used to construct mathematical models of ice-covering load,wind load and insulator flashover under extreme weather through historical weather data and actual line parameters,to obtain the vulnerability model of the transmission line,and then to determine the fault conditions in the whole system.Secondly,the Monte Carlo simulation method and the convergence condition of the objective function are used to find out the optimal access point of the mobile power vehicle,and the mobile power vehicle is dispatched to improve the system resilience.Finally,the simulation analysis is carried out by using the data of the self-consistent energy system of a highway service area in Xinjiang.The results show that compared with the commonly used method of fixing the access point of mobile power vehicles,the dispatching method proposed in this paper increases the proportion of loads that are restored to the power supply by 12%,which enhances the efficiency of mobile power vehicle and the resilience performance of the self-consistent energy system.
