Due to the climate crisis, the importance of reducing greenhouse gas (GHG) has been recognized by governments, private companies and the general public alike. Yet carbon capturing-based approaches are difficult to integrate with transportation, which is one of the largest GHG producing sectors, Therefore, electrification is the only viable approach to reduce emissions from transportation, by greatly increasing the market share of electric vehicles (EVs). However, the mass adoption of either (or both) of battery EVs (BEVs) and fuel cell EVs (FCEVs) require a large amount of supporting infrastructures, particularly the construction of EV charging stations (EVCSs) for BEVs and hydrogen refuelling stations (HRSs) for FCEVs. The goal of this study is to provide effective approaches for the sizing and sitting of EVCSs and HRSs to facilitate the deployment of BEVs and FCEVs. The background and an overview of the thesis are provided in Chapter 1, where the gaps in the current research are pointed out and the objectives of the thesis are formulated. Chapter 2 reviewed the current state of technologies regarding the hydrogen life cycle as well as the popular planning models for EVCSs and HRSs. In Chapter 3, to achieve a competitive strategy from the perspective of private companies, a market-based framework is proposed for the problem of EVCS planning by leveraging Graph Convolutional Network (GCN) and game theory. In Chapter 4, a multi-objective planning model is developed for EVCSs and the expansion of distribution network with significant renewable components while considering uncertainties in EV charging behaviour. Additionally, in Chapter 5, a planning model of HRS maximises the long-term profit while considering different practical constraints. The HRS planning model also addresses short-term demand uncertainty via redistribution. The models that are developed in this study are validated using either synthetic or real-world case studies, and the simulation results showed the effectiveness of the proposed models. ...

Ethics is the science that studies the theoretical part of the human condition and its values. The individual has the responsibility to conduct ethic decisions and to have an ethical behavior. This article presents the ethics from the research and engineering perspective, its main characteristics; lack of honesty, confidentiality, conflict of interests and intellectual property. The engineering teaching is the act which includes multiple ethic subjects in order to educate the student about the importance of ethics and its repercussions. The students have the right to benefit of ethical behavior from their teachers from the staff of the school. The ethic is essential in all the educational and working fields, but we insisted specially on the electrical engineering field.

The professional role of electrical services engineers is evolving and changing to meet the needs of industry, both national and internationally. The current demands throughout the built environment are primarily driven by European Directives and Government policies pertaining to sustainable design, energy reduction and energy efficiency. Thus, it is essential that Ireland's Higher Education Institutions meet these challenges head on by developing diverse programmes which have sustainability at the core of curriculum design. Moreover, programmes of this nature will ensure that young engineers of the future command key transferable skills and enhance their lifelong learning which is required for today's competitive labour market. What will the engineers of the future look like – would they be recognisable from today? This pedagogical research intends to examine the development and restructuring of an existing curriculum for a level 7 degree in Sustainable Design in Electrical Services Engineering in Ireland. The programme maintains the core learning outcomes, which have been reviewed by an accreditation body, while providing engineering graduates with a host of diverse multidisciplinary skills. This curriculum development has been tailored to meet the needs of industry, but more importantly the needs and expectations of future students. How does a programme ensure students are employable? This paper offers a unique insight into engineering education as both authors are graduates of the aforementioned programme and have subsequently returned to lecture on the programme. Moreover, they have been heavily involved in the curriculum development.
