Stochastic Stability Analysis of New Energy Power System Based on Entropy

Power system as an open dynamic system, on the one hand, it must always ensure the quality of power; On the other hand, it suffers from constant interference, and its location, type and severity are quite uncertain. With the development of new energy generation, the traditional power system model and the analysis method of entropy criterion can not reflect the stochastic problem of power system with new energy generation, and is no longer suitable for the actual system. Taking wind power generation as the representative of new energy power system, this paper summarizes the entropy stability criteria of stochastic power system by using differential equation and combining with the existing stability discrimination methods such as mean stability and mean square stability, analyzes the application scope of various kinds of stability, and carries out simulation analysis with specific examples.
