1. Hybrid energy storage systems : Capacity optimization and environmental implication of hybrid energy storage systems in renewable power systems
Abstract : Electricity production contributes a large share of greenhouse gas emissions that lead to climate change. At present, power generation in many parts of the world still heavily depends on fossil fuels. To prevent global warming, the electricity sector is supposed to transition from the current fuel mix to renewable energy sources. READ MORE

2. On Stability Enhancement in AC/DC Power Systems through Multi-terminal HVDC Controllers
Abstract : Due to the increasing share of renewable energy sources in modern power systems and electricity market deregulation, heavy inter-regional and cross-border power flows are becoming a commonplace in system operation. Moreover, large-scale integration of renewable energy sources is expected to pace up, therefore new solutions have to be developed to integrate these intermittent sources, which are also characterized by being distributed over large geographical areas, such as offshore wind farms.

4. Active High Voltage Insulation - A New Hybrid Insulation Concept with Dynamic and Active Features
Abstract : In this thesis, the concept of a new environmental-friendly and high-performance high voltage insulation is presented. Basically, it is an electric field steering technique where the dynamic process of charge accumulation, actively and advantageously, re-distributes the electric field within an insulation system.

5. Sustainability and development impacts of off-grid electrification in developing countries : An assessment of South Africa's rural electrification program
Abstract : Previous studies have shown that provision of sustainable electricity supply to rural households is essential to bring development to off-grid populations. For this reason, most developing countries put large efforts into rural electrification programs to stimulate development and reduce poverty. READ MORE
