Study on optimization model control method of light and temperature coordination of greenhouse crops with benefit priority.

•An optimization model control method expands the research on coordinated energy conservation and optimal control of greenhouse environment.•Based on the NSGA-II genetic algorithm, Pareto’s optimal frontier is obtained with the objective of minimizing energy consumption and maximizing the predicted crop yield.•The results showed that the average power consumption before and after optimization was about 4.31 % when Pn was basically unchanged. When the power consumption is basically the same, the average Pn increase is about 9.59 %.
