Demonstrating Interactions of Distribution Network and Local Energy Communities Operating in Hierarchically Autonomous Control Architecture Paradigm
Challenge and objective
There are limited physical implementation cases of LECs from which distribution network operators and policy makers can learn.
The operational interaction between LECs and the distribution network remains largely unaddressed.
Work performed
A real-time simulation approach is discussed and implemented as a supplementary approach to account for the operational impacts of LECs.
Hierarchically autonomous Energy Management Systems (EMSs) are implemented together with simulated network to highlight some of the benefits of such high-fidelity simulation studies.
Specifically, a CIGRE LV network with a LEC on one feeder is studied under different operational scenarios.
Significant results
The results highlight issues which might be overlooked when doing active-power-based battery and flexibility scheduling to solve the overloading of MV/LV transformer.
The simulation results reveal that active power scheduling and planning of flexibility activation based solely on active power may result in overloading or voltage limit violations.
Impact for distribution system innovation
A simulation platform has been esablished to study and demonestrate impact of LECs on distribution network operation.
