高速公路微电网研究

Research on Microgrid of Expressway

针对高速公路供电呈带状、供电距离长、负载耗电量小、地理位置分散等造成的供电难且费用大的问题,介绍了微电网的概念及其特点,并对现有微电网的优势进行了分析;结合高速公路现状给出了高速公路微电网管理系统结构模型,对风电互补设备、储电设备、负载进行系统论述;研究高速公路微电网在孤岛和并网两种运行模式下电源、负载、储电池的运行状态,给出相应的运行策略。分析表明,高速公路微电网可实现。

In order to solve the problems of difficulty in power supply and high cost because of the long distance, low power consumption by the load and the sprawling of expressways, microgrid and its characteristics were introduced, and the advantages of current microgrid were analyzed. Structural model for the management system of microgrid was proposed for expressway. Wind power complementary equipment, power storage equipment and the load were related. The status of power, load and the battery of microgrid in island mode or connected to the grid was studied, and corresponding operation strategies were put forward. The analysis shows that the idea of microgrid for expressway is feasible.
