Abstract

This paper details a Smart Grid Laboratory for the study of modern house distribution systems with multiple energy sources and energy regeneration capability. The laboratory is designed to perform real-time simulation of a realistic distribution system connected to multiple houses. In addition, a real house with typical appliances and power sources is connected to the eMEGAsim real-time simulator with a Power- Hardware-In-the-Loop (PHIL) interface. Such PHIL interface enables the simulation of a simulated plant and real devices at a connection point where actual energy is exchanged between the two parts. Because of the coupling delays and the bandwidth of the plant and real devices, the stability of such a PHIL connection is not guaranteed. This paper will have a special emphasis on the stability of such power-HIL simulation.

Abstract

Real-time simulation requires the use of fixed step integration methods, capable of achieving accuracy with a time step range larger than 10 μs to 100 μs, to enable the use of standard processors and IO systems. Simulation accuracy increases when the time step value decrease but the processing power and number of processors increase when the time step decreases. The choice of integration techniques is also important. Simulation specialists must therefore select the best integration technique and time step that will yield to acceptable results. This document provides a comparison between simulation results obtained by using a classical 2nd order Tustin integration solver (also known as the Trapezoidal method) and the ARTEMIS 5th Order integration Method). The TUSTIN 2nd order method uses two terms of the Taylor series of the exponential function, while ARTEMIS 5th order uses five terms. Tustin is used by conventional electrical simulation software using the nodal technique such as PSCAD and EMTP while SimPowerSystems and eMEGAsim use ARTEMIS 5th order method in addition to the TUSTIN method.
