DTU Intelligent control laboratory

The intelligent control lab (ICL) of PowerLabDK was used for the lab demo of dynamic tariff. It is a full scale power system control room for technology development without disturbing real power system operation or real customers. The system setup of the ICL is shown in Figure 1.

Figure 1 The ICL system setup

The ICL comprises a real time digital simulator (RTDS), a full-scale SCADA system and full-scale experimental power system control room, with a link to the Bornholm power system data, an IBM blade centre for optimization and control implementation, and different hardware interfacing with the RTDS for hardware-in-the-loop (HIL) and power-hardware-in-the-loop (PHIL) tests. The hardware in the Electric Lab integrated with the ICL is an Spitzenberger & Spies power amplifier with 150 kW continuous power supply capability, a LabGrid with 21 LabCell boards, Omicron amplifiers, relays, an electric vehicle with vehicle-to-grid (V2G) capability, , photovoltaic (PV) panels, and micro combined heat plant (µCHP) units.

 

Lab Demonstration of Dynamic Tariff

The demo setup is shown in Figure 1. It consists of a real time digital simulator, three desktops representing the DSO and two aggregators and the communication channels by DNP3 and OPC protocols.

The lab demo of the dynamic tariff (DT) aims to achieve the following goals.

  1. Test the convergence of the centralized and distributed optimization in an environment close to real life
  2. Test the efficiency of the prices determined by the DC OPF in the AC power system;
  3. Test the impact of uncertainties on the efficacy of the DT concept
