Training Example 1

DER Management

Introduction

This exercise demonstrates an ANM project on a small rural distribution network.

 

It focuses on the fundamentals of DER control and integration to the wider enterprise, addressing real time network analysis and comparing effectiveness of manual and automatic thermal and constraint management.
