The invention relates to a method for photovoltaic grid connected coordination control based on the MAGA. The method for photovoltaic grid connected coordination control based on the MAGA is characterized by comprising the following steps that large-scale photovoltaic grid connected coordination control architecture composed according to the MA technology is established; parameters of each Agent are collected and each Agent is controlled; information is transmitted and fed back; photovoltaic grid connected coordination control is achieved through the MAGA; the information is fed back and further optimization is achieved. According to the method for photovoltaic grid connected coordination control based on the MAGA, a micro-grid system composed of a large-scale photovoltaic power generation system, a fuel cell, a storage battery and the like is controlled through the MAGA technology according to the characteristic that the photovoltaic power generation system has access to a power distribution network, the maximum-efficiency output of the photovoltaic power generation system is achieved, the power supply reliability of the system is improved, and the efficient use of energy is achieved.
