technical challenges
T1 : Power system design is a key parameter for the introduction of Distributed Energy Resources(DER)
T2 : Existing distribution networks present a significant “hosting capacity” for Distributed Energy Resources
T3 : The “hosting capacity” of present networks can be extended based on “static” voltage adjustment or on active management
T4 : Further increasing the ”hosting capacity” implies active management and new design criteria
T5 : A new “symmetrical” and “flexible” design is proposed as an example allowing for higher Distributed Energy Resources (DER) penetration
T6 : In the long run the “hosting capacity” for RES could be extended further with RES most often considered as a source of power than as a source of energy
T7 : Power System controls can be deeply affected by DER, requiring adequate system integration
energy value
E1 : A load demand database has been set up permitting the detection of high potential demand segments for DER
E2 : Physical model of end uses have been set up for modelling electrical and thermal load demand
E3 : Simulation tools have been developed or upgraded for modelling the impacts of DER on thermal and electrical load demands
E4 : As a first step to profitability, the energy value of a single DER unit must be optimised
network value
N1 : The current “Use of System” charge schemes cannot valorise DER that represents value for the system
N2 : Efficient “Use of System” tariffs can be set up to unveil the value of DER as a “network replacement”
N3 : New tariffs for “Use of System” should lead to a long-term reduction of system costs
service value
S1 : in the present status of the electricity market, DER are already able to deliver services to the system
S2 : in the future additional services could be delivered by DER because distribution networks will no longer be designed following the "fit & forget" principle.
aggregation
A1 : Aggregation scenarios and their commercial value
A2 : Four sources of values can already be captured by aggregation businesses
A3 : Appraising today’s consumer acceptance of innovative DER offers in 3 countries (UK, Greece, Germany)
A4 : Expansion of DER aggregation needs minimum common requirements in ICT infrastructure
A5 : A 50-parameter analysis allows DER aggregation business models in a given local context to be assessed
A6 : Four potential scenarios for 2020 picture different future outcomes for DER aggregation businesses
A7 : A validated toolbox allows the economic evaluation and optimisation of DER-portfolio operation
field tests
Test 1 : Testing the integration of a composite CHP system for market interaction, “office buildings” segment, Grenoble France
Test 2 : Testing the integration of a composite tri-generation system for market interaction, “educational buildings” segment, Athens Greece
Test 3 : Testing the technical feasibility of aggregating 10 kW to 1.5 MW scale DER in the UK commercial market segments
Test 4 : Testing the technical feasibility of aggregating Micro-CHPs in the German residential sector
Test 5 : Testing the technical feasibility of a decentralised control architecture for aggregation of load and generation
business model 1
i1 : A promising business based on balancing intermittent generation by aggregating demand response in the UK
i2 : Aggregating Demand Response can be profitable in the UK under current regulation
i3 : Demand Response aggregation businesses rely heavily on customer portfolio characterisctis and market conditions
i4 : Germany and France could become two interesting countries for businesses based on aggregation of Demand Response
i5 : Extrapolation to 2020 shows that aggregation of Demand Response looks even more promising for the future
business model 2
ii1 : An aggregation business case for residential-scale flexible CHP integration in electricity markets
ii2 : The Micro-CHP aggregation business model is difficult to implement under the current German regulatory regime
ii3 : Micro-CHP aggregation business can be profitable under certain conditions
ii4 : Micro-CHP business is more profitable in Germany than in France and in the UK, while the added value of aggregation is higher in the UK
ii5 : Flexible support schemes and investment cost reduction would guarantee interesting rates of return in 2020 for micro-CHP aggregation business
business model 3
iii1 : Leveraging on the flexibility of aggregated CHP units and demand response to extend the conventional Energy Service Company business
iii2 : Flexible ESCO aggregation business can be profitable in Belgium today
iii3 : Flexible Distributed Energy Resources (DER) can offer risk-hedging opportunities for portfolio management
iii4 : Flexible ESCO aggregation business can be profitable in Belgium, UK and Germany, while the structure of the support schemes makes such business unfeasible in France and Spain
iii5 : Flexible ESCO aggregation business will experience more profitability in the future
Recommendations
R1 : Recommendations for future large scale experiments
R2 : Distribution regulation and network design represent key parameters for the integration of Distributed Energy Resources
R3 : Beyond EUDEEP: Recommendations to standardisation bodies
