The invention discloses a power system intermittent renewable energy consumption capability evaluation method considering frequency safety. The method comprises the steps of obtaining structure parameters, load data, synchronous generator set parameters and intermittent renewable energy electric field parameters of a power system; constructing linear frequency constraint of the system according to a first-order constant coefficient differential equation of system frequency deviation dynamics; defining an intermittent renewable energy output robust feasible region and establishing a system operation risk model, and then establishing a power system intermittent renewable energy consumption capability evaluation model considering frequency constraint; the evaluation model is converted into a solvable compact mathematical model, and a column and constraint generation (Column and Constraint Generation, Camp; and the CG algorithm is solved through a solver, and an evaluation result is obtained.
