The ever-increasing electrification of society has been a cause of utility grid issues in many regions around the world. With the increased adoption of electric vehicles (EVs) in the Netherlands, many new charge points (CPs) are required. A common installation practice of CPs is to group multiple CPs together on a single grid connection, the so-called charging hub. To further ensure EVs are adequately charged, various control strategies can be employed, or a stationary battery can be connected to this network. A pilot project in Amsterdam was used as a case study to validate the Python model developed in this study using the measured data. This paper presents an optimisation of the battery energy storage capacity and the grid connection capacity for such a P&R-based charging hub with various load profiles and various battery system costs. A variety of battery control strategies were simulated using both the optimal system sizing and the case study sizing. A recommendation for a control strategy is proposed.

More and more local bottom-up energy initiatives are emerging. Those involved encounter many barriers during the realization of their ideas. As the generation of renewable energy is mostly included, these local initiatives contribute to the targets set at regional, national & EU level. At the same time, they are an indication that end-users themselves want to be part of the energy transition. What are the reasons for citizens to organize themselves and start and initiative? What kind of barriers do they encounter? What does this mean for roles and responsibilities of professionals? And to what kind of opportunities does this lead for products and services? Answers to these questions provide a solid starting point to develop methods and instruments to stimulate,facilitate and upscale local energy initiatives. This paper bundles the outcomes of three workshops and three additional interviews in the Netherlands as part of the European E-hub project. Conclusions can be drawn on needs and drivers, barriers, risks and solutions (lessons learned), possible roles for professionals and opportunities for new products and services.

New technologies or approaches are being widely developed and proposed to be deployed in real energy systems to improve desired objectives; however, supporting decision making processes to select best solutions in terms of performance and efficiently following cost-benefit analysis require some sort of scientific evidence based tools. These tools should be reliable, robust, and capable of demonstrating the behaviour and impact of newly developed devices or algorithms in different pre- defined scenarios. Therefore, new approaches and technologies need to be tested and verified using a safe laboratory test environment.This report is about the development and realisation of some major tools and reliable methods to calculate risks and opportunities for integrating of new energy resources into the European electricity grid. Hanze University Groningen and Politecnico di Torino worked together within the STORE&GO project sharing laboratories, knowledge, hardware facilities and researchers for the realisation of the characterisation and mathematical modelling of renewable resources. Needed to realize a stable and reliable environment for remote physical hardware in the loop simulations.For this realisation we started with the local characterisation of a PV-Field and a PEM electrolyser at Entrance Groningen by logging and measuring the electric behaviour and specific device parameters to integrate and convert these into working mathematical models of a PV-Field and electrolyser prosumer. After testing and evaluating these models by comparing the results with the real-time measurements, these test and modelling is also realised from the remote laboratory in Torino. To achieve dynamical physical hardware we also realised dynamic mathematical model(s) with real-time functionality to interact directly with the remote electrolyser. To connect both the laboratories with full duplex communication functionalities between physical hardware and models we have also realized a network which is able to share network resources on both local and remote sites.

Hanze Entrance participeert in een ISPT project met 15 deelnemers uit de industrie om te onderzoeken welke routes richting elektrificatie werken voor de industrie. Met meerdere cases wordt data opgehaald om generieke vergroeningspaden d.m.v. elektrificatie binnen de industrie te realiseren.Beoogd projectresultaat:Een functionerende ‘eerste opstelling’ van een prosumer heathub op EnTranCe. Dit Warmte Ontvangst Station kent meerdere facetten van lokaal hergebruik en herdistributie na opslag van warmte. Daarvoor wordt de ringleiding, WKO en andere facetten op Entrance volledig geïntegreerd. Deze integratie geeft Warmtestad de mogelijkheden om Entrance als een wijkstation te ontwikkelen. Het eindresultaat is een beslisboom en business case voor meerdere wijkstations op basis van de use-case EnTranCe.
Hanze Entrance ontwikkelt in een consortium een onderwijs infrastructuur voor de toekomstige ‘Heat Heroes’. Het bedrijfsleven wil samen met het MBO en HBO onderwijsveld een opleidingsomgeving creeren die de warmtetransitie in de gebouwde omgeving middels warmtenetten kan versnellen. Dit doet zij door een bi-directionele warmteverbinding tussen Hanze Entrance en Warmtestad aan te leggen en de infrastructuur op Entrance vergaand onderling te integreren en digitaliseren. Entrance fungeert hier met meerdere bronnen (electrolizers, H2-WKK, warmtebuffers) als een ‘prosumer’ die warmte kan afnemen en terugleveren aan warmtestad. Het project wil met een interdisciplanaire aanpak alle aspecten van warmtetransistie op Entrance kunnen testen, emuleren en/of onderzoeken. Hiermee wordt deze infrastructuur een uniek ontwikkelplatform en het fundament waarmee het consortium onderzoek doen en onderwijs-ontwikkelingen worden gestoeld.Beoogd projectresultaat:Een functionerende ‘eerste opstelling’ van een prosumer heathub op entrance.
