Distributed real-time simulation allows the sharing of simulator equipment and components connected in Hardware-In-the-Loop experiments. In this paper, we analyze the challenges of geographically distributed real-time power system simulation and how dynamic phasors could be applied to improve the accuracy of the simulation results for large time steps. The time step is of particular interest since...
Approximate analytical solution of linear or nonlinear ordinary differential equations (ODE) can be obtained by Adomian decomposition (ADM) method. The nonlinearities in the ODEs are approximated by Adomian polynomials and a rapidly convergent sequence of approximate functions will be obtained as a solution. The ADM is widely used for numerical simulations of real-world systems in the applied sciences...
This paper proposes a new method of decoupling and subdividing electrical circuits, containing power-electronics devices, in order to achieve fast and accurate real-time simulation. In this technique, each state variable can be discretized using different discretization methods. Combining implicit and explicit ODE solvers, state-space equations are decoupled while remaining accurate and stable. Unlike...
This paper presents a real-time simulation of a synchronous generator using real-time application interface (RTAI) on Linux. Different generator controllers such as exciter and power system stabilizer are also included in the real-time simulation. The Forward Euler method with a suitable step-size has been employed for obtaining the solution of differential equations after justifying its applicability...
