A Calculation Method of the Characteristic Quantity of a New Energy Power System Considering Complex Influencing Factors

The input of a traditional power system is usually deterministic, but with the increasing installed capacity of new energy access systems such as wind power and photovoltaic, its energy sources are random and fluctuating, which makes the uncertainty of the power system significantly enhance. In this paper, the limitations of traditional methods in analyzing power systems containing new energy are introduced. With the aim of solving the problem that it is difficult to investigate the influence of various system characteristics on random input, a calculation method of new energy power system characteristics considering complex influencing factors is proposed. By combining the Taguchi orthogonal test method and the Gaussian mixture model, the calculated system characteristics can reflect the characteristics of a new energy power system under various working conditions.
