同时，边缘物联代理装置还接收区域能源光控装置下发的并网点功率控制指令，接收到该指令后，通过调度光伏设备发电功率、储能设备充放电功率、电动汽车充电功率，优先满足并网点功率要求，将并网点功率控制在目标区间，当分布式光储充装置统一并网接入点功率联合控制不满足并网点功率控制要求时，可以及时反馈区域能源管控装置，区域能源管控装置接收到反馈信息后，完成并网点功率控制指令调整并再次下发。At the same time, the edge IoT agent device also receives the power control command of the grid connection point issued by the regional energy light control device. After receiving the command, it dispatches the power generation power of photovoltaic equipment, the charging and discharging power of energy storage equipment, and the charging power of electric vehicles to give priority to meeting the requirements. The power requirements of the grid-connected point, and the power of the grid-connected point is controlled within the target range. When the unified control of the power of the grid-connected access point of the distributed optical storage and charging device does not meet the power control requirements of the grid-connected point, the regional energy management and control device can be timely fed back to the regional energy management and control device. After the device receives the feedback information, it completes the adjustment of the power control command of the grid connection point and sends it again.
