This report discusses the design and implementation of a subsystem required for the Illuminator, which is an energy system integration demonstrator. The purpose of the subsystem discussed in this report is visualising incoming simulated power flows, visualising the output data of various emission and finance data and also change various input parameters. This system has been realised using Dash, which is the python framework used for building the dashboard web application. A study case is provided to better understand the use of the demonstrator.

To follow the rapid advance of the Energy Transition, the technology and application of the renewable energy resources and energy storage devices have been developed in an unstoppable speed. When the application of energy storage technology starts to prosper gradually over the world, there are some problems showing up while lots of advantages are being advocated. There are plenty of batteries staying unused or being wasted for over half of the lifetime of the system, especially for the behind-the-meter energy storage system. The business models are usually built just for one or two primary services for customers and grid that makes only a limited part of time occupied, leaving the essential untapped values aside. And also, it is common that the energy storage system is coupled with PV panels or wind turbines. In this case, how to increase the on-site solar energy self-consumption becomes an attractive issue considering the sizeable financial benefit it can bring. What is more, when putting the attention on the neighborhood or community level where there is more than one participator in this picture, how to create the extra value or bonus benefit using the existed system and equipment can be an interesting topic. This report will focus on the grid-size battery installed behind the meter within a commercial community. A methodology of the energy hub with two different lays providing all kinds of services will be proposed. As the result, the value of grid-size energy storage in enabling a community-level energy hub for both battery-owner and neighbors will be explored to cope with all the above problems. There will be a case study conducted in the selected Zuid-Oost Amsterdam region. In the end, how much benefit the energy hub can create for not only the battery-owner but also for the whole community and society will be discussed.

The growing global population combined with improved prosperity has increased the energy demand. The consequence of this growing energy demand is an increase in greenhouse gas emissions leading to climate change. The irreversible and worrying consequences of climate change have led to various national and international targets. In the Netherlands, national targets are integrated into policy making in 2019, distinguishing between five sectors. This study aims to describe a systematic approach that contributes to facilitating decision-making in the heat transition in the built environment. The approach consists of three steps, considering the system elements of a socio-technical environment. The first step of the systematic approach is formed by an actor analysis, where through an actor identification and categorization the non-rational aspects are mapped. These non-rational aspects, consisting for example of willingness to participate in the heat transition and underlying technological preferences, can be used to determine the social feasibility of a heat transition vision. The second step in the systematic approach is the application of the techno-economic Vesta MAIS model. This model can calculate at a neighborhood level per heat transition vision the national cost and share of energy carrier. In this way, the model contributes to facilitating decision-making at the municipal level. To enrich the technical aspects of the Vesta MAIS model with insights into grid congestion, this study proposes a power flow analysis as the third step in the systematic approach. This power flow analysis enables municipal decision-makers to analyze the impact of the heat transition on the existing power grid at an early stage.
