Calculation of the Limit Acceptance Capacity of Renewable Energy

Due to the randomness and uncertainty of wind power, the integration of wind power into the grid will increase the insecurity factors of the power system, so it is necessary to study the impact of wind power on the power system. In this paper, the maximum active power output of the new energy unit is solved under the combined action of frequency constraint and short-circuit ratio constraint, and the simulation and verification are carried out in MATLAB using the actual system example.
