风光储 Droop 控制策略改成了 V/f 和 PQ 控制策略，并应用 MATLAB/Simulink 进行了仿真(The Droop control strategy of the system is changed into V/f and PQ control strategy, and the simulation is carried out by using MATLAB/Simulink)

Since the first edition of this book was published seven years ago, the field of modeling and simulation of communication systems has grown and matured in many ways, and the use of simulation as a day-to-day tool is now even more common practice. With the current interest in digital mobile communications, a primary area of application of modeling and simulation is now in wireless systems of a different flavor from the `traditional ones. This second edition represents a substantial revision of the first, partly to accommodate the new applications that have arisen. New chapters include material on modeling and simulation of nonlinear systems, with a complementary section on related measurement techniques, channel modeling and three new case studies a consolidated set of problems is provided at the end of the book.

this code is an feature extraction called histogram of gradian(HOG)

ast Algorithm estimating the number of sinusoids in a white Gaussian noise. This algorithm use a sub-space method based on chi-square statistics of eigen values of the Autocorrelation Matrix.
