Bachelor Thesis: Entwicklung und Implementierung von Analysekonzepten für das fortiss Smart Energy Living Lab

Abstract:

Im Rahmen dieser Bachelorarbeit wurde eine Erweiterung für den fortiss Smart Energy Demonstrator entworfen und implementiert. Diese Erweiterung ermöglicht dem Nutzer, sich verändernde Werte der hauseigenen Sensoren und Aktuatoren, zu beobachten. Dabei wurden sowohl Langzeitbetrachtungen als auch Methoden zum Vergleich unterschiedlicher Sensoren oder Zeitpunkte implementiert.

Zusätzlich wurden mit Hilfe einer Mustererkennung, bei gemessenen Signalen, Spitzen- werte erkannt. Diese Spitzen stellen beispielsweise Indikatoren zum Energiesparen dar.

Anschließend wurden die implementierten Funktionen mittels der vorhandenen Daten im fortiss Smart Energy Demonstrator evaluiert und bewertet.

Bachelor Thesis: Design and realization of a smart energy prosumer interface for user interaction with the Living Lab

Abstract:

With the decision of the German government to completely switch to renewable energy sources until 2025 and only using conventional power plants to kick in if there is to much drain on the grid. To make this plan a reality the power grid has to be turned into a so called smart grid that not only carries the power but at the same time is self aware and self healing. To bring this concept further the consumers have to be smart as well and at best tell the grid when they need the energy. This thesis will present a possible user control system for such a smart office environment developed by fortiss called Living Lab. The control will be developed for an Android mobile device.

Bachelor Thesis: Design and Implementation of an Android Application to Control and Monitor the fortiss Smart Energy Living Lab

Abstract:

The Smart Energy Living Lab is a demonstrator for a Smart Micro Grid, consisting of sensors, actuators and smart meters, which are in- terconnected via a messagebus to a server application and a database. The aim of this Smart Micro Grid is to measure and control the energy flow. In the context of this thesis an Android application was developed that provides the user with an overview of the device states and allows him to alter those states.

Bachelor Thesis: Design and Implementation of a Right and Role Management System for the fortiss Smart Energy Living Lab

Abstract:

This thesis introduces concepts regarding access control for the Smart Energy Lab. Implementing a straightforward right and role management, along with a low-level permissions checking mechanism, this design addresses safety and security concerns while conforming to the central principles of Smart Grids, such as high extendibility. Along with the technical solution, a first analysis of the typically encountered actors and their functional permissions is presented.

Bachelor Thesis: Smart Grid-Demonstrator: Office Employee Module

Abstract:

This thesis introduces an IT-system controlling a Smart Micro Grid – the Living Lab demonstrator. The demonstrator is set up in an office environment consisting of a set of home automation devices and external systems. A Service Oriented Architecture was realized following several design principles for a highly extendable distributed system. The whole system is designed to control all connected devices in a way that puts the ideas of the Smart Grid which are focused on energy efficiency and communication between different participants of the grid into practice and will be the base for research projects approaching the subject “Smart Grid” and “Smart Micro Grid” from multiple points of view.

Paper: Smartphones as Multisensors in Smart Building Environments

Abstract:

This paper aims to integrate smartphones into a smart building environment. Stress is laid upon integrating the sensor capabilities of the smartphones which has not been done previously. In addition a profile system is introduced to allow users to automatically adjust room settings. To assign users and data to the room they are currently located in, a localization mechanism is proposed. After presenting relevant aspects of the system a proof of concept is evaluated.

Paper: An Energy Management System for a Smart Office Environment

Abstract:

The evolution of the electricity grid towards the smart grid paradigm is fostering the integration of distributed renewable energy sources in Smart Buildings: a combination of local power generation, battery storage and controllable loads can greatly increase the energetic self-sufficiency of a Smart Building, enabling it to operate in islanded mode or to participate in an Automatic Demand Response framework, thus taking advantage of time-variable tariffs to achieve economical savings.

This paper proposes an energy management system specifically tailored for a Smart Office building, which relies on actual data and on forecasting algorithms to predict the future patterns of both local energy generation and power loads. Performance is compared to the optimal energy usage scheduling, which would be obtained assuming the exact knowledge of the future energy production and consumption trends, showing gaps below 10% w.r.t. the optimum.

Paper: Advancement of a Sensor Aided Smart Grid Node Architecture

Abstract:

Flexible, extensible and lightweight architectures are necessary to allow the participation of small energy producers in the smart grid. In addition to an intelligent energy management system on top of a home control system these nodes exchange information with other smart grid components to establish energy trading as well as a stable and scalable smart grid subsystem. In order to support future developments in the areas of communication protocols, sens- ing and metering devices, actuators, production and stor- age technologies a flexible and extensible design is essential. The proposed enhanced architecture supports a distributed deployment on small and energy-saving computing devices to decrease visibility and energy consumption as much as possible. In the further implementation of the layered approach we distinguish between core components and func- tional components. Connected via an enterprise message bus the components can be implemented using different programming languages and deployed on various networked devices following the SOA principles. The core components form a consistent system including authentication, configuration, persistent storage and registration of functional com- ponents. Hereby, the registration component allows for the easy integration of different sensors and actuators and is responsible for the interaction of the core system and the lower device layer. Other functional components support energy production and consumption forecasting, analysis of historical data, and self-optimization capabilities. In this paper, the design and functionality of our layered and component based architecture is presented. The implemented system provides open interfaces for the integration and utilization of additional smart grid and smart home components in a plug and play manner.

Paper: Establishing a Smart Grid Node Architecture and Demonstrator in an Office Environment Using the SOA Approach

Abstract:

The introduction of low-cost renewable energy production, e.g., by photovoltaic, has turned classical grid nodes like homes and offices in prosumers, taking an active role in smart energy systems by merging home-automation and energy production functionality. However, to become a self-balancing element of a stable smart grid, supporting the energy-aware cooperative production, storage, and consumption, a scalable software is needed, tailored for smart micro grids and their integration in large-scale systems. In the following, the imple- mentation of a layered SOA-based distributed architecture is presented, that provides open interfaces simplifying the plug- and-play of hardware and software components.
