Future grids with Decentralised Power Production



Objective and ApproachMain objective:• Preparation of a new distributed generation structure of

power supply in regional, local and island grids

Approach• Investigation on basic solutions for technical problems

expected from more decentralised generation in distribution networks

• Demonstration of exemplary technical solutions in test centres and at selected sites

• Restriction on medium and low voltage grids

DISPOWER – research areasGrid stability and control• Stable operation of networks with very high penetration of DG• Control of DG and storage plant• Hardware and control strategies for load management• Advanced communication and metering

Power quality and safety• Power quality of LV connected DG• Development of a power quality and management system for DG in

LV networks• Concepts and solutions for preventing unintended islanding• Protection against overload and short circuits in DG networks• Identification of requirements for new standards for DG



DISPOWER – research areas(continued)

Socio-economic issues• Evaluate the potential of the users as “controllable” load • Influence of ICT and innovative distribution networks on the

penetration of DG• Effect of institutional changes in the electricity markets and strategic

behaviour of incumbent utilities on the position of DG




Planning, trading and operation tools• Adaptation of a simulation tool for load flow calculations in DG

networks with wind power plants• Development of software tools for optimisation of grid connection

of wind farms• SCADA system for DG and controllable loads• Training facilities and programme for grid operator personal

Information, communication, and electricity trading• Standardised data structures and data bases for information services• Wind power prediction tool for wind farms in UK to improve

energy trading




Test facilities for grid stability, control and power quality • Test facility for power quality at CESI, Milano (transient and energy

flow analysis)• Test facility for grid stability and control at ISET, Kassel (test of

DG units, setup of laboratory DG grid)



Test facility for grid stability and control at ISET




Implementation of DG technology in regional power supply systems

• Case studies for DG in European interconnected networks• Case studies for DG in European islands and weak grid

Pilot installations and monitoring of DG in low voltage grids• Solar Settlement Querdeich (PV/ micro turbine / battery storage)• Technology Demonstration Centre San Agustin del Guadalix (PV/

Wind/ Battery)• Stadtwerke Karlsruhe (Fuel cell, battery storage)
