Community energy management with FlexMeasures, fully scriptable

AW1.126
Nicolas Höning
<p>Optimally planning the energy flows across multiple sites becomes more important, e.g. for orchestrating the aggregated flows due to grid congestion, or for implementing energy sharing. This approach can break bottlenecks and increase savings - as such, energy communities are an important topic for the European Commission.</p> <p>In this talk, we present our ongoing work towards a Community Energy Management System (CEMS) with FlexMeasures. We discuss our architectural approach: optimizing the flows for each sites by themselves and then adding an orchestration layer on top. This approach is being tested in a project with TNO in the Netherlands. The goal is to manage neighbourhoods as well as commercial sites optimally.</p> <p>In addition, we want to discuss how scalable any CEMS system can be, as many circumstances and conditions often vary, per site and per energy community. We chose our CEMS architecture approach for this reason, but versatility has been a design principle for FlexMeasures since the beginning. In this talk, we will showcase a complete example script of a setup orchestrating a few homes. This script is written with the FlexMeasures client and is also open source. FlexMeasures being 100% scriptable is a design choice that lets many developers built just what they need in energy intelligence.</p> <p>This is also an opportunity to visit some fundamental improvements we have made in the last year in the documentation of FlexMeasures and its flexibility options - both for developers and users.</p>

<p>In France, thanks to the deployment of 37 million Linky smart meters, a vibrant open-source community has emerged, developing smarter, greener, and more open energy-management systems powered by Linky’s locally emitted data. Enedis, the main French DSO, now works alongside this community to accelerate the use of its meters’ data for the energy transition. Open hardware, open software, open data—all of this is key to meeting the challenges !</p>

<p>Presenting the Energy System Description Language (ESDL) open-source community, which is currently being built around the open standard ESDL and the ecosystem of open-source tools that work with ESDL. There is a dozen tools that are being used by several companies and initiatives to design energy hubs, heat networks and develop scenario's to best integrate new battery, hydrogen, solar and wind assets within grid with limited available capacity.</p>

<p>Solar energy is predicted to be the largest form of power generation globally by 2040 and having accurate forecasts is critical to balancing the grid. Unlike fossil fuels, renewable energy resources are unpredictable in terms of power generation from one hour to the next. In order to balance the grid, operators need a close estimate of when and how much solar and wind power will be generated on a given day. </p> <p>Open Climate Fix (an open source AI company) developed and deployed PVNet, a ...

<p>Storing energy reversibly is useful. For clean energy, electrochemical batteries are one of the most attractive options. Most battery technology is proprietary, hard to recycle, and complicated to manufacture. What if that wasn't the case?</p> <p>We will present our collective and individual efforts with the Flow Battery Research Collective (https://fbrc.dev/) to build open-source batteries for stationary storage applications. This includes our flow battery work, such as efforts to build a ...

<p>Standards like OCPP and ISO 15118 describe how EV charging should work, yet real-world deployments often behave differently. This session explains why a full stack of tools, testing methods, and feedback loops is essential for true interoperability, and how the open-source EVerest ecosystem has become a practical integration point for these technologies. We will show how Software-in-the-Loop testing, Golden SUT validation, conformance tooling, virtual charger parks, testing-hackathons, and ...
