Landis+Gyr ANM solution validation report 4. Validation results The objective of the project is to demonstrate the capabilities of the TOSHIBA / Landis+Gyr solution and show how it can be used to remove the technical barriers associated with connecting DER to distribution networks. For this purpose, different scenarios have been tested using the laboratory setup. The use cases are representative of the real challenges of operating a distribution feeder with renewable generation and variable load. Extreme scenarios in which both voltage and feeder currents exceed set limits have been created. Each use case is defined by: a load profile; a renewable generator’s power generation profile; line characteristics; list of field devices available for the μEMS to control. 4.1 Voltage fluctuation Figure 4 shows the programmed load profile and power output from the generator connected to Bus-3 (end of the feeder) for the test period. Figure 5 shows the resulting Bus-3 voltage profile measurements if no control action is performed.
