The Danish Cell Project - Part 1: Background and General Approach

The paper presents the current situation in the Danish power system, which is unique as more than 50% of the total production capacity is dispersed throughout local distribution grids of 60 kV voltages and below. This characteristic has lead to the cell controller pilot project which aims at developing a new solution for optimal management and active grid utilisation of the large amount of distributed generation present in Western Denmark.

I. Introduction

The power systems of Denmark are characterised by a high penetration of distributed generation (DG) comprised of small to medium scale combined heat and power plants (CHP) and wind turbines (WTs). This is especially true in the western part of Denmark where 75% of all Danish WTs are situated. In 2004 local CHP made up 30% and WTs 23% of the electricity consumption of that area.
