Smart Grid Deployment and Climate Change Response: Evaluating Climate Change Integration in Ontario's Smart Grid Deployment Regime

Smart grid (SG) is modern electricity infrastructure that has the capacity to facilitate mitigation and adaptation to climate change through technological, institutional, and behavioral interventions. However, despite the capacity to respond to climate change, development and deployment of SG technology also has the potential to facilitate increased GHG emissions or result in the development of a maladaptive grid. By formally integrating climate change considerations into SG deployment regimes, electricity stakeholders can mitigate the risk of contributing to GHG emissions or implementing a maladaptive grid as well as ensure that SG deployment facilitates a comprehensive and efficient response to climate change. The purpose of this research was to explore the SG deployment regime in Ontario between 2004 and 2013 within the context of climate change. Specifically, this thesis aimed to evaluate evidence of climate change integration within Ontario’s SG deployment regime and identify gaps in climate change integration. Ultimately, the objective was to identify areas of SG deployment where climate change integration could be strengthened to assist stakeholders in implementing a SG that results in a positive and comprehensive response to climate change. Through a content analysis of publically available documents published by electricity stakeholders, it was found that several SG initiatives inadvertently demonstrated climate change integration or an inadvertent response to climate change. There was no evidence that electricity stakeholders explicitly considered climate change in SG deployment activities. In particular, gaps were identified in components of climate change integration related to climate change impact assessments, project evaluations, long-term planning, and consumer education and public awareness. Overall, it is recommended that electricity stakeholders take measures to explicitly consider climate change in future SG deployment activities. As Ontario is a global leader in SG deployment, climate change integration in Ontario’s electricity sector could set a precedent and inspire other jurisdictions pursuing SG technology to do the same, both across Canada and globally

An assessment framework for walkability in Libyan city centres: public spaces in Tripoli

Libyan civic and urban centres are increasingly suffering from unwalkable places due to the lack of legislation for accessibility, multiplication of unregulated car traffic, and the absence of adequate urban and spatial planning. In the last few decades, there has been an increasing interest in the field of walkable public open space as a key driver of sustainable urban development and redistribution of land use, to ensure pedestrian and walkable routes between sites of living and workplaces, and to reduce dependence on automobiles. However, in most developing countries, including Libya, there is limited a comprehensive approach and framework to enable and facilitate walkable public open spaces in urban centres. This research analyses factors and identifies barriers related to walkability in public open spaces in Tripoli (Libya) in two phases: exploring the consistency and validity of effective walkability factors related to the context, using surveys with 25 Libyan specialists, experts, and decision makers; and developing a mixed methodological approach to assess and evaluate current perceptions, attitudes, and aspects involved in determining what makes an accessible and walkable urban space in Tripoli. The empirical study included analysis of a questionnaire survey (using SPSS version 20.0) of 427 users and 108 professionals, and observation of spatial practices and attitudes in four different public spaces in the city. Focus group discussions were used to validate the results, which showed that safety and security; lack of facilities, and physical barriers; institutional, legislative, management and financial barriers; social and cultural barriers; and transportation system barriers, with varying weights, hinder people's decisions to walk in public open spaces in Tripoli. A framework was developed to assess the significance and extent of these walkability problems that can be used as a basis for public open space making and management in developing countries' urban planning

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

Förderung des Aufbaus von Smart Grids in Thailand als Zusammenspiel von intelligenten Gebäuden, intelligenten Verbrauchern und einer intelligenten Energiepolitik

Smart grid technology can enhance renewable energy in the electricity system by integrating information communication technology (ICT) into the existing electricity network. Residential and commercial buildings can perform as a power plant with an energy design concept by integrating renewable energy and energy storage system. However, there has been relatively little focus on how to enhance the residential sector in smart grid development in the context of Thailand. This research focuses on residential buildings only. The technology assessment shows that energy efficiency measures (EEM) must be implemented to reduce the energy demand of the building. The Ice thermal energy storage system (ITES) is an appropriate energy storage system application that can provide cooling energy, which is the major energy consumer in residential building. The integration of EEM, the PV system, and the ITES system can reduce the primary energy demand by 87%, compared to the reference building without comprehensive energy concept design. The power quality assessment shows that the PV hosting capacity is limited up to 75%, which keeps the voltage level in the permissible range. The distributed energy storage system allows the PV prosumer to perform an active role by providing reactive power service to the system at the critical electricity feeder. The economic assessment reveals that the ITES is the most cost-effective investment option, where the battery energy storage (BES) system can become more attractive with incentive support and future cost reduction. The results from the consumer survey reveal that the willingness to pay (WTP) of the EEM and PV system in the detached single-family house is higher than the investment cost, which benefits both consumer and house developer. Technology is a key driver for providing the energy service to the energy system, while consumer behavior and acceptance can increase technology adoption. The Thai government should encourage the residential sector to become a smart user by taking technology, consumer behavior background, and essential energy policy into account.Intelligente Netztechnik, sogenannte Smart Grid-Technologie, kann durch die Einbindung von Informations- und Kommunikationstechnologie die Integration von erneuerbaren Energien in das bestehende Stromnetz verbessern. Wohn- und Gewerbegebäude können mit Hilfe eines Energiekonzepts durch die Integration von erneuerbaren Energien und Energiespeichern als Kleinkraftwerk fungieren. Allerdings gibt es in Thailand bisher wenig Analysen, wie man den Wohnungssektor für die Entwicklung intelligenter Netze nutzbar machen kann. Diese Forschungsarbeit konzentriert sich daher ausschließlich auf Wohngebäude. Die Technologiebewertung zeigt, dass Energieeffizienzmaßnahmen (EEM) umgesetzt werden müssen, um den Energiebedarf der Gebäude zu reduzieren. Ein thermischer Energiespeicher basierend auf Eis (ITES) ist eine geeignete Speicheranwendung, um Kühlenergie bereitzustellen, die der Hauptenergieverbraucher in Wohngebäuden ist. Durch die Integration von EEM, dem PV-System und dem ITES-System kann der Primärenergiebedarf um 87% reduziert werden, verglichen mit einem Referenzgebäude ohne umfassendes Energiekonzept. Die vorliegende Forschungsarbeit zeigt, dass die PV-Aufnahmekapazität auf bis zu 75% ausgeweitet werden kann, ohne dass Spannungsgrenzen verletzt werden. Der dezentrale Energiespeicher ermöglichst es zudem dem PV-Prosumer, durch Blindleistungseinsatz eine aktive Rolle im Stromsystem einzunehmen und Spannungsprobleme in kritischen Leitungssträngen zu reduzieren. Die wirtschaftliche Bewertung zeigt, dass das ITES die kostengünstigste Investitionsoption ist und das Batteriespeichersystem (BES) durch Anreize und künftige Kostensenkungen an Attraktivität gewinnen kann. Die Ergebnisse der durchgeführten Verbraucherbefragung zeigen, dass die Zahlungsbereitschaft für die EEM und das PV-System in Einfamilienhäusern höher ist als die Investitionskosten, was sowohl dem Verbraucher als auch dem Bauherrn des Hauses zugutekommt. Neue Technologien sind zentrale Elemente, um die Bereitstellung von Energiedienstleistungen im Energiesystem zu ermöglichen. Jedoch sind auch Nutzerverhalten und -akzeptanz wichtig, um die Verbreitung der Technologie zu erhöhen. Die thailändische Regierung sollte den Einsatz von Intelligenz im Wohnungssektor fördern und dabei Technologien, Verbraucherverhalten und wesentliche energiepolitische Aspekte berücksichtigen
