A major key to the energy transition is making sure devices use energy when it is available: when the sun shines or the wind blows. A lot of flexible devices can be found in every household: by activating for example an electric boiler at the right time, a flexibility provider helps the energy system on one hand, and on the other hand the boiler owner earns some money for that. There’s one problem However: Flexibility providers have no means to know how many boilers can be activated in the same street without jeoperdizing grid integrity. Therefore they have to play it safe resulting in a lot of flexibility that is not put to good use. Soteria creates a way for parties to work together to make better use of the available devices and grids!
The Soteria concept brings existing and new building blocks together: A new market is created where flexibility providers send their aggregated bids including locational information and system operators share their grid constraints forecasts in advance. A market clearing algorithm calculates the most beneficial solution for all stakeholders. The market outcome is validated by the system operators to ensure no grid constraint are violated and finally the flexibility is activated by the flexibility providers in a grid-secure way.
Step 0: Share Virtual Power Plant (VPP) information
Step 1: Gather grid insights from devices and digital meters
Step 2: Publish grid bandwidth for flexibility
Step 3: Offer flexibility to market, after which the market clears within the specified grid constraints
Step 4: Cleared market schedule sent for validation to the system operator
Step 5: Schedule approved by grid logic agent
Step 6: Activation of residential flexibility
Step 7: Audit trail & settlement information gathered from digital meters
1 | Growth of RES is putting our grids under pressure
Electricity systems in the EU and US are “decarbonizing” rapidly. The integration of intermittent and distributed renewable energy sources is however pressuring our electricity grids.
2 | Demand response is a key enabler of the energy transition
Demand response, is a critical resource for achieving a low carbon, efficient electricity system at a reasonable cost.
3 | But there is a huge potential of unused flexibility at distribution level
But a large part of the available residential flexibility cannot be leveraged towards system operators due to the limited information sharing between the grid operators, flexibility providers and flexible consumers.
4 | Bring more revenue streams to prosumers
Within the IO.Energy Soteria project, Belgian energy leaders will connect all stakeholders to transform uncoordinated activations by residential assets (e.g.DR-ready electric boilers) into grid-secure demand response, maximizing the value for residential electricity consumers and stabilizing the energy system.
Fluvius is the Distribution System Operator for Flanders, with the mission to sustainably connect society through multi-utility solutions. As founding father of IO.E it will co-create a grid logic agent for IO.E that solution providers can interact with, enabling them to develop new services for customers in coherence with the physical grid. In doing so, IO.E becomes an infrastructure connecting the digital and the physical world.
