A new algorithm for isolated electricity supply system control

... systems and their control, including emergency control, represent a difficult problem that needs to be studied. Generation from wind power plants, however, is a vivid example of stochastic operation of generators. The research is aimed at developing algorithms for the construction of automated systems to control active components of the electrical network. The method applied in the research to describe the object of control is based on the universal approach to the mathematical modelling of nonlinear ...
