Measure of reliability tools for simulating electric power systems and alternative approach of their verification

Approach in the modeling of wind turbines for power system stability studies and evaluation of their impact on electric power systems

“…Hardware and software simulation tools appropriate for modeling failing with this problem in virtue of the limited mathematical calculations, and the impossibility of solving large systems of differential equations describing processes in EPS. Moreover, when solving the systems of differential equations by numerical methods, the computational error accumulates, which reduces the reliability of the simulation results [4][5][6]. Various scientific community and research laboratories when modeling large wind parks are necessity to apply certain limitations and assumptions, applying equivalent models in calculations.…”

The selection of interval boundaries of input and output data method for obtaining complete probabilistic characteristics

“…Unlike standard methods, the method does not require integration, transformation of the original PF. Also, unlike modifications of the Monte Carlo method [1,7], the SIBD does not require an increase in the number of tests according to the number of random arguments to obtain a statistical representation of the result with the required accuracy [6,10].…”
