Energy System Flexibility
|
|
The use of renewable energy sources is key to reducing the carbon footprint of energy systems, though given their variable nature they generate difficulties in balancing the production and demand. Combining multiple energy carriers can provide the system with the needed flexibility. As the EU strategy on energy system integration states, "linking sectors will allow the optimisation of the energy system as a whole, rather than decarbonising and making separate efficiency gains in each sector independently."
This May the Celsius Initiative is partnering up with the Flexi-Sync and MAGNITUDE projects in the hope of shedding some light on how sector integration can improve the flexibility of district energy systems. For an even deeper dive into the subject, you are cordially invited to join the discussion during the Celsius Talk: Energy System Flexibility on Tuesday May 25 at 10:00 CET.

Flexibility Through Multi-Energy System Integration
The Horizon 2020 project MAGNITUDE addresses the challenge of integrated energy systems to bring under a common framework, technical solutions, market design and business models, to maximise flexibility provision. The goal is to enable an improved level of flexibility for the European electricity system by increasing and optimising synergies among electricity, gas and heat systems.

To foresee rapid changes in consumption and weather conditions and adjust the delivery in a district heating system with an inherent inertia is quite an art to master. There are some strategies and tools that are developed to aid the system optimisation on the utility-side.

Friendly Sam is a toolbox developed to formulate optimisation-based models of energy systems, so-called dispatch models. By creating models with an overarching system perspective on the energy system, different sectors can be integrated, such as heating, cooling, and electricity.

District energy utilities and property owners can both benefit from the optimisation of demand-side flexibility, for example by investing in thermal storage and buildings with both district heating and heat pumps. This approach can enable the optimisation of district energy flexibility.

When done properly, stakeholder engagement can be the key to the success of a district energy network. Yet, there are many different stakeholders, and each is to be engaged in a particular way. In the framework of the 2021 Euroheat & Power Congress Virtual Thursdays, the Celsius Initiative is partnering up with the REWARDHeat and ReUseHeat projects to address the question of how utility companies can better engage with the end-users.
