The invention discloses a perovskite solar cell grid-connected control method and system, and the method comprises the steps: carrying out the energy collection of a perovskite solar cell, and calculating the output of a perovskite solar cell grid-connected controller; meanwhile, the Euclidean distance between the perovskite solar cell and the power grid voltage at the current moment is calculated, and the power control vector of the perovskite solar cell is updated; and the above process is circulated to realize real-time steady-state enhancement of the perovskite solar cell grid-connected control. According to the size of the Euclidean distance between the perovskite solar cell and the power grid voltage, the perovskite solar cell grid-connected control method can be rapidly converged and has good robustness, so that the problems of unstable power generation and power grid voltage fluctuation of the perovskite solar cell under the influence of the environment are further reduced. 本发明公开了一种钙钛矿太阳能电池并网控制方法及系统包括
