Renewable Electrical Energy Laboratory (REE LAB): Scaling Version of Cyber-Physical Energy System

DESCRIPTION

The growing amount of renewable energy sources leads to wheeling electrical power over long distances and to the growth in power electronics-based generation. Both affect the behavior of the electrical power system. The objective of this testbed, scaled version of the cyber-physical energy system, is to investigate operation and control possibilities of future power systems. This setup allows to change the rotational inertia, analyze all terminal quantities with phasor measurement units, define different operational states and scenarios. With this laboratory implementation, electromechanical swings such as inter-area oscillations after disconnecting a tie-line, changing loads and generation or tripping a synchronous machine can be shown. Based on this implementation, it is possible to study the influence of important quantities such as inertia. This testbed can be used to test PMU behavior, SE techniques, PSS control of WADC.

AREAS OF SPECIAL COMPETENCE

Cyber-physical energy system: Testbed combines electrical energy system with ICT system. It allows investigating technologies behavior close to a real environment.

WHAT CAN BE TESTED

Investigation of RES/BESS (low inertia) impact on power system dynamics.
Investigation of equipment/protection behavior in cases with high ROCOF
Testing and validation of advanced wide-area measurement, control and damping systems
Validation of data-driven solutions - oscillation detection, classification and source allocation

AVAILABLE INFRASTRUCTURE

The testbed consists of four identical synchronous machines with variable inertia, scaled electricity transmission network, resistive and inductive loads, four PMUs connected to WAMS.
