The invention discloses an evaluation method for adequacy of a wind generation and energy storage hybrid power system. According to the evaluation method, a deterministic criterion and a probability method are combined on the basis of a Well-being theory, the running state of the system is divided into a healthy state, a boundary state and a risk state by adopting a deterministic method, and then, the probability method is adopted to evaluate the adequacy of the system. The division of the system state is realized under the consideration of the adequacy of a power generation system and the adequacy of a power transmission system, so that the calculated adequacy indexes under the various states are more scientific, and can reflect the running condition of the actual system better.
