The invention relates to an optimization method and system for a biogas co-generation system of a farm. The method comprises the following steps: constructing an energy supply side heat model and a heat demand quantity model; the energy supply side heat model represents the relationship between the provided heat and the biogas amount and the feed amount for biogas power generation; the provided heat comprises heat provided by a generator and heat provided by a boiler; the heat demand quantity model represents the relationship between the heat demand quantity and the feeding quantity of the anaerobic fermentation tank; determining a heat demand constraint model according to the energy supply side heat model and the heat demand model; constructing a heat supply model by taking a heat demand constraint model, a generator set power constraint model, a gas-fired boiler power constraint model and a biogas amount constraint model for power generation as constraint conditions and taking the maximum investment yield a
