The invention relates to the technical field of electric power engineering, and discloses a multi-scene charging facility overload early warning method comprising the following steps: collecting historical power grid load information of a target charging system in a specific time period, and presetting a standard interval according to the historical power grid load information; real-time power grid load information of a target charging system is obtained, whether the real-time power grid load reaches a preset standard interval or not is judged, and if yes, a corresponding early warning signal is sent to a charging main control system; transmitting power distribution information to a vehicle-mounted charging facility according to the early warning signal; and the vehicle-mounted charging facility receives the power distribution information, calculates a limited charging current according to the power distribution information, and judges the current charging current and the limited charging current. Periodical division is performed on historical power grid load information, and the current charging condition is regulated and controlled according to the division condition, so that the current charging system is regulated and controlled according to different scenes.
本发明涉及电力工程技术领域,公开了一种多情景充电设施的负荷过载预警方法,包括:采集目标充电系统在特定时间周期内的历史电网负荷信息,并根据所述历史电网负荷信息预设标准区间;获取目标充电系统实时电网负荷信息,并判断所述实时电网负荷是否达到预设标准区间,如果是,则向充电主控系统发送相应的预警信号;根据所述预警信号向车载充电设施传递功率分配信息;所述车载充电设施接收所述功率分配信息,并根据所述功率分配信息计算限定充电电流,并判断当前充电电流与所述限定充电电流大小。通过对历史电网负荷信息进行周期划分,并根据划分情况对当前充电情况进行调控,从而根据不同的情景对当前充电系统进行调控。
