Energy-economic model for transition to renewables
… of extraction. The production of energy from renewables is dependent on investment, innovation, and a natural limit to energy production. We also seek to include an aspect of investment in technology through the inclusion of e ciency and innovation factors. Two models of growth are examined …

Renewables Integration Challenges of the Energy Transition
… in Britain, as well as some potential solutions. Renewables integration is investigated using a multidomain methodology to process and model live data. Using a knowledge graph supported infrastructure, the British energy network is modelled. This consists of a representation of Britain’s …

Nuclear-renewables energy system for hydrogen and electricity production
… mix of energy technologies. Nuclear and renewables attract attention because of their ability to produce electricity while cutting carbon emissions. However their output does not match demand. This thesis introduces a nuclear-renewables energy system, that would produce electricity and …

Frequency Stability Constrained Grid Operation with High Penetration of Renewables
<p>Achieving carbon neutrality necessitates a significant integration of renewable energy into power systems. However, the swift implementation of fluctuating renewable energy (VRE) sources such as solar photovoltaics (PV) exacerbates real time power imbalances due to the randomness and uncertainty …

Sustainable Operations of Production and Service with Onsite Renewables Integration
… energy technologies is an increase in the renewables share of the electricity generation from the demand side and a reduction of the systems' environmental footprint. In particular, we apply techniques of optimization under uncertainty to determine the optimal operation of manufacturing and …

Implementing community renewables: institutional work in South Africa's renewable energy procurement programme
… the implementation of South Africa's community renewables, government and companies dominate institutional work efforts in the stages of policy formulation and project development. But communities, the least informed and capacitated actor among the three, face the results and they have …

Risk implications of the deployment of renewables for investments in electricity generation
… of plants in a system where the intermittency of renewables accentuates nonconvex costs, without over-increasing the cost paid by consumers for electricity. Additionally, the analysis quantifies the potential losses incurred by different thermal technologies if renewable deployment occurs without …

Global Capitalism and the Energy Crisis: Challenges and Opportunities Associated with a Transition to Renewables
… and direct investment. With reference to renewables, a transition to hydroelectricity, in particular small-scale hydropower plants, could decrease long-term energy costs, aid in providing a secure energy supply and reduce the effects of climate change. Energy and natural resources are a …

The synthesis of Combined Heat and Mass Exchange Networks (CHAMENs) with renewables considering environmental impact
Process synthesis is used to evaluate different potential designs to select the most suitable that fulfils some process goals. There is ever-increasing pressure to reduce operating cost and emission of pollutants as energy prices continue to increase and more regulations are set by government. To …

Distinct roles for energy storage and transmission infrastructure in a renewables-based electric power system
… components in the system are dependent on the renewables penetration toward total demand—known as the energy availability factor (EAF). When the EAF is sufficiently low, the cost of a cost-optimized system is driven solely by generation costs. For low to intermediate EAF, both generation and …

Early detection, classification and proactive mitigation of cyberattacks in microgrids embedded with renewables and electric vehicles charging infrastructure
Microgrids are localized energy systems that can operate independently or in conjunction with the main utility grid. Microgrids incorporate renewable energy resources such as solar panels, wind turbines, and increasingly support the deployment of Electric Vehicle Charging Stations (EVCSs). This …

The benefits and challenges of renewables on the electric grid and opportunities for systems integration and demand side management
Environmental policies, reduced manufacturing costs, and technology improvements have all contributed to the growing installation of wind turbines and solar photovoltaic arrays in the electric grid. While these new sources of renewable electrical power provide environmental and economic benefits to …

Modelling and optimisation of the dynamic performance of a reversible solid oxide fuel cell system for the grid intergration of renewables
Along with the increasing concerns on environmental issues, the penetration level of renewable energy is growing fast, e.g. wind, tide and solar energy. However the impact of renewable energy on the conventional power grid is increasing due to their intermittent characteristic of power supply. As a …

A stakeholder-grounded evaluation of the seven functions model of technological innovation systems theory in UK offshore wind and marine renewables.
… thirty influential participants in the offshore renewables sector - including project and technology developers, policy makers, supply chain, support organisations and other stakeholders - the thesis examines whether the seven functions provide a "necessary and sufficient" framework, to …

Energy and sustainability transitions: the case of community renewables for off-grid rural electrification in Nigeria with emphasis on Shape community project.
The transition from one energy system to another has been analysed by many researchers especially in the context of developed countries. Community renewable energy transition in rural areas is largely under-researched, particularly in developing countries. This study developed a model based on …
