Test Specification TC9.TS02

Test Rationale

The goal of this Test is to evaluate the performance of the indirect method considering the impact of the communication latency and packet losses on a LV grid congestion management.

Specific Test System

The Test System includes a LV (0.4 kV) network with realistic data provided by a local utility company. This network consists of three feeders with various loads and PV systems connected along the feeders.

In addition to the above network, a market model is also developed.

Target measures

Voltages, currents of all grid components and grid services cost.

Input and output parameters

Weather condition (hence DER production), grid topology, household load profiles, controllable generation production

Test Design

Initialize the simulation; achieve a steady state condition; trigger a congestion condition (peak of load or peak of generation); evaluate the response of the DMS controller; reinitialize the simulation and repeat the test with different congestion condition and the baseline.

Initial system state

Transformer and feeders loading in permissible ranges.
