Experiment Realisation

The experiments require testing Raspberry-based MAS communicating to a grid simulated in a real-time simulator via power amplifiers. All PV systems are implemented and embedded in the real-time simulator along with the studied grid.

Experiment Setup (concrete lab equipment)

The experimental setup is as shown in the figure below.

The following lab equipment are included in the experiment:

  • OPAL-RT eMegaSim OP5600 (or OP-5700)
  • A cluster of Raspberry PI 4 Model B 4GB
  • Ethernet switch
Experimental Design and Justification

Different operating conditions will be applied in order to generate under/over voltage issues within the simulated grid. Consequently, the MAS will react to these voltage violations, process the measurement input and then communicate with each other to generate appropriate controlling output signals to their corresponding PV inverters simulated inside the real-time simulator.

The time delay and packet loss will be also created to test the performance of the proposed MAS and the implemented distributed voltage control under different communication scenarios. The ability of the MAS-based distributed voltage control system with a lack of information has an advantage over the centralized voltage control strategy.

Precision of equipment and measurement uncertainty
  • OPAL-RT simulation time step: Ts = 5e10-6 s
  • Packet losses due to the limitation of transmission rate of network cards
