PowerMatching City

PowerMatching City is part of the Integral Project: a consortium of eleven European partners seeking to build and demonstrate an industrial-quality reference solution for the aggregation level control and coordination of distributed energy resources, or, in other words, a smart grid. The Integral Project gets its name from the project partners’ ambition of designing an integrated coordination system for three typical network situations: 

•          Normal operation 
•          Critical situations 
•          Recovery from blackouts

For each of these three situations, a demonstration project is being built. The results of the field tests will be used to realize a generic coordination mechanism.

PowerMatching City is one of the three demonstrations, focusing on ‘normal operation’. The demonstration has been realized by DNV KEMA in cooperation with ECN, Essent and Humiq. The coordination mechanism developed by the means of this field test addresses the question of how a market can be structured, so as to promote the interests of all stakeholders: 

•          Prosumer: maximizing economic benefit 
•          Network operator: reducing peak loads 
•          Producer/Supplier: minimising imbalance costs by using the cluster as a virtual power plant                                                                                   

In Hoogkerk, a suburb of the Dutch city of Groningen, 25 homes have been equipped with a mix of decentralized energy resources (PV-solar, microCHP and hybrid heat pumps), smart appliances, smart meters and electric vehicles. Together they are called the PowerMatching City project. Wind energy is also supplied by the Kreileroord wind farm. Stabilization and optimization of the network are realized by trading energy on a local market, based on a realtime price signal using the PowerMatcher concept.
