Landis+Gyr ANM solution validation report 3. Validation setup In order to test the functionalities of TOSHIBA’s µEMS in a real and controlled environment, TECNALIA’s smart grid laboratory is used. TECNALIA’s laboratory features flexible, low-voltage infrastructure that can adopt different network topologies and run either connected to or isolated from the main power grid. It includes different renewable generators, storage technologies, loads and controllable equipment. For this project, a particular laboratory setup representing a distribution feeder with renewable Figure 1: View of one part generation and loads connected at various points to this feeder (Figure 2) has been selected. of TECNALIA’s smart grid Different scenarios were generated and analyzed by programming the power output from the laboratory generator and the loading profiles. The characteristics of the line impedance have been taken into account as well: All of the tests are performed with purely resistive, purely inductive and mixed-line impedance. Bus-1 Bus-2 Line simulator Bus-3 Tap Simulation Data Setting Load 2 for each equipment model Load 3 Gen 3 TVR simulator L 4 G 4 Storage simulator TOSHIBA’s µEMS is capable of sending control commands to a wide variety of field devices. For Figure 2: Simplified one-line this demonstration project, a Thyristor Voltage Regulator (TVR) and a Battery Energy Storage diagram of the test feeder System (BESS) have been used. In order to test the capabilities of the control system under extreme conditions, load and generation control capabilities have also been implemented for those extreme scenarios. It was impractical to move a TOSHIBA TVR and battery energy storage system to TECNALIA’s premises, which is why a TVR and a BESS have been simulated using laboratory hardware and specifically designed software. The TVR simulator is implemented by means of two laboratory 6
