Smart Grid Laboratory has been established in 2015 year.

SGLab has advanced power system components whose inter-operation can be observed:

  • Electrical energy storage (Li-Ion batteries used in electric vehicles)
  • 3 industrial inverters rated 2250 VA / 1800 W each
  • 20 PV modules:
    • 10 polycrystalline silicon modules (130 W per module for 1000 W/m2 solar irradiation with 1m2 panel area)
    • 10 monocrystalline silicon modules (140 W for 1000 W/m2 solar irradiation with 1m2 panel area)
  • Different load types (linear, nonlinear, drives)
  • Distributed generation model (5.5 kW microturbine and 1.5 kW cogeneration)
  • DC drive driven engine that simulates a 15 kW thermal power plant (busbars, protection equipment, metering equipment)
  • 20 kW hydroelectric power plant with a Pelton turbine (with turbine governor and rated flow of 27 liters/s)
  • A system of power lines with corresponding circuit breakers that simulate a transmission grid
