PHOTOVOLTAIC POWER GRID CONTROL METHOD AND DEVICE

A photovoltaic power grid control method and control device. The control method comprises: obtaining a control instruction of a photovoltaic power grid (S10); obtaining current state information about the photovoltaic power grid (S20); calculating, according to the control instruction, the current state information and a pre-set regulation strategy to obtain a target instruction of each node in the photovoltaic power grid (S30); and regulating the output power of each node according to the target instruction of each node (S40). The method and device can automatically control the switch-on and switch-off of an inverter of a photovoltaic power grid; remote control is realized, the response time is short, the regulation error rate is small and the labour cost can be reduced; and meanwhile, the operation safety of the power grid is improved. La présente invention concerne un procédé de commande et un dispositif de commande de réseau électrique photovoltaïque. Le procédé de commande consiste à : obtenir une instru
