Applications for this project have now closed.
Recent studies estimate that close to two-thirds of the world’s population live in rural areas and around 1.3 Billion people, mainly living in South Asia and Sub-Saharan Africa, have little or no access to electricity.
As an alternative to conventional large-scale electricity grid infrastructure is the use of off-grid integrated renewable energy systems (IRES) coupled with community scale microgrids, which can offer low-carbon electricity supply using locally available renewable resources.
Biogas, produced though anaerobic digestion from local biomass resources which are abundant across much of the global south, can play a role in electrification whilst delivering additional benefits such as improved indoor air quality, public health and sanitation, reduced gender inequality and promotion of sustainable agriculture.
This PhD project will investigate the design, operation, implementation and long-term community acceptance of rural electrification systems using biogas and other renewable technologies and will involve both modelling and field-based investigation.
The project will involve an interdisciplinary approach and would seek to understand the interrelated criteria for successful IRES based energy projects. For example: (1) appropriateness of technology and optimised system scaling, (2) quantification of the electrical demand and its links to current and future behaviours, (3) understating criteria for community uptake and long-term acceptance of the technology and, (4) the provision of a dependable electrical supply by robust control of the microgrid and component energy systems.
- Investigation and assessment of renewable resource availability in Sub-Saharan Africa and South Asia, in areas where biogas based rural electrification projects could be feasible.
- Development of electricity demand prediction tools based on community type, economic activity, population and wealth, including how demand changes over time e.g. based on changing attitudes or increased economic activity.
- Optimisation of microgrid operation, component scaling and reduction in energy storage, using modelling tools, based on a variety of resource availability and electrical demand scenarios.
- Design of advanced hierarchical control strategies for high quality electricity distribution across a variety of timescales.
Investigation of the key factors that promote acceptance or rejection of electrification in non-electrified communities
Through the existing international collaboration between the University of Sheffield and Visva Bharati in India, the work will benefit from access to a rural electrification site that is currently powering 45 households across two Indian villages. The student will be expected to travel to India in order to perform technical and social field studies on both this system as well as other non-electrified villages nearby.
