Abstract: Agricultural greenhouse integrated energy system（AGIES）is a multi energy complementary agricultural greenhouse system that requires in-depth consideration of environmental conditions for safe crop growth, in order to optimize regulation of multi-source equipment power and achieve economic and low-carbon operation of the system．Low-carbon control method for AGIES considering crop safety was proposed．Electricity, gas and heat energy structure of AGIES was established．Power model of agricultural equipment was also established．Energy conversion mechanism of energy flow and power coupling devices was clarified．Safety boundaries of light, temperature and water supply for crop growth were studied．Reasonable range of sunlight and light exposure for crops, indoor constant temperature heating power range, scientific water supply and electricity power range and electricity time range were proposed, and mathematical models were used to describe in detail．Carbon emission accounting indicators for electricity, gas, and heat were proposed．Power optimization control model with the lowest comprehensive operating and carbon emission costs was established．Particle swarm optimization algorithm was used to solve and optimized energy consumption plan was obtained．Feasibility and effectiveness of proposed method were verified through numerical simulations．
