背景技术Background technique
在化石能源和环境污染的双重危机下，大力开发和利用可再生能源是解决这一问题的有效途径。受风电、太阳能资源特性影响，可再生能源发电出力具有间歇性、波动性的特点，本发明主要指风电、太阳能发电，大规模可再生能源发电并网情况下会对传统配电网的调度运行产生巨大影响。而随着电池储能技术的提高，电动汽车的大量普及，负荷侧也能体现柔性特性参与电力系统调度，成为促进可再生能源消纳、实现削峰填谷和提高配电网灵活性调节的重要手段。Under the double crisis of fossil energy and environmental pollution, vigorously developing and utilizing renewable energy is an effective way to solve this problem. Affected by the characteristics of wind power and solar resources, the output of renewable energy power generation has the characteristics of intermittent and fluctuating. This invention mainly refers to wind power and solar power generation. When large-scale renewable energy power generation is connected to the grid, it will have a huge impact on the dispatching operation of the traditional distribution network. With the improvement of battery energy storage technology and the popularization of electric vehicles, the load side can also reflect the flexible characteristics and participate in power system dispatching, which has become an important means to promote the consumption of renewable energy, realize peak shaving and valley filling, and improve the flexibility adjustment of distribution network.
现阶段国家大力推进电动汽车的普及，我国电动汽车销量在2012年到2016年持续增长，2016年电动汽车销量已达23.32万辆，纯电动汽车以电力作为驱动力，减少了传统燃油汽车对化石能源的依赖。据调查发现，用户电动汽车90％的时间都处于停放状态，利用电动汽车进行移动分布式储能潜力很大。单个电动汽车的充电功率较小，一般采用电动汽车充电站进行电动汽车充放电统一管理，实现电动汽车的有序充放电。电动汽车充电站收到电网下发的控制命令后，采集目前电动汽车充电台数和各个电动汽车的SOC值，通过优化计算得到各个电动汽车的充电功率，增加和减少负荷功率。At this stage, the country is vigorously promoting the popularization of electric vehicles. The sales of electric vehicles in my country continued to grow from 2012 to 2016. In 2016, the sales of electric vehicles reached 233,200. Pure electric vehicles use electricity as the driving force, reducing the dependence of traditional fuel vehicles on fossil energy. According to the survey, users' electric vehicles are parked 90% of the time, and the use of electric vehicles for mobile distributed energy storage has great potential. The charging power of a single electric vehicle is small, and electric vehicle charging stations are generally used for unified management of electric vehicle charging and discharging, so as to realize the orderly charging and discharging of electric vehicles. After the electric vehicle charging station receives the control command issued by the grid, it collects the current number of electric vehicle charging units and the SOC value of each electric vehicle, and obtains the charging power of each electric vehicle through optimization calculation, and increases and decreases the load power.
当前电动汽车充电站运行方式相关研究主要集中在作为可控柔性负荷的控制模式研究，其研究结果不符合实际电力系统调度情况，无法为电力系统调度运行人员提供有效依据。The current research on the operation mode of electric vehicle charging stations mainly focuses on the control mode research as a controllable flexible load. The research results do not conform to the actual power system dispatching situation, and cannot provide an effective basis for power system dispatching operators.
