Most of current demand response schemes assume that the operation of DER (Distributed Energy Resources) will be centrally managed by an aggregator or a cooperative utility. However, this centralization of the control suffers from scalability issues when the number of DER increases. B-DER wants to decentralize the control to avoid these problems and manage the energy as locally as possible.Increase the value of local energy
Currently in The Netherlands, prosumers are selling a kWh produced with solar panels in the centralized energy market for the same price than consuming a kWh. This will change for sure in a near future, decreasing the value of solar production in the utility market. Then, an alternative local market would let the prosumers to establish the energy value they want, giving priority to the local energy over the utility energy.Solutions
A peer-to-peer energy trading platform will empower end-users
allowing them to sell their surplus energy (produced by their PVs) to
other households in the neighbourhood or to EV charging stations.
The algorithm will maximize the use of locally produced energy while
minimizing electricity costs. The platform will be tested using PV
production data and EV charging station demand from a residential
neighbourhood in Amsterdam. The resulting algorithm will use a
block-chain architecture to enable secure and verifiable
decentralized energy transactions.
The analysis has been done with a prosumer community of 23 households with solar panels, 3 of them with a domestic EV charger and another 3 with heat pumps. Check the project website
- Analysis of hourly energy data (consumption and solar production)
- Study the impact of EV’s demand in a prosumer community
- Definition of a local market with simple energy-exchange rules
- Study the effect of local EV demand shifting on increasing the community self-consumption ratio and users cost
- In sunny months, the production rate is similar to consumption rate at the end of the day, so the introduction of energy flexibility elements and a local market would make a change
- The introduction of 3 EVs’ demand suppose an increase of 20% the households demand
- From the energy point of view, most of the year the EV’s could charge during the day, when there’s no households demand, increasing the use of local solar energy
- From an economic point of view, with a local market this flexibility on EV’s demand would be translated to less cost for EVs’ users and more benefits for the prosumers with energy surplus.
