The electrification of transportation, and especially aerospace transportation, increases the demand for high performance electrical machines. Those machines often need to be fault-tolerant, cheap, highly efficient, light and small, and interface well with the inverter. In addition, the development time and cost are usually limited, with little...

Should risks always be quantified before being managed? The answer is “yes” in the opinion of most asset managers in today’s electricity transmission and distribution companies, but “no” in modern theories of risk management. When the risks refer to reliability hazards of high-voltage assets, the answer to the above question is “yes, it should...

It has been predicted that due to the population growth the energy demand is increasing faster and faster. It has been well recognized that depleting fossil-fuel resources will not fulfill the energy need of the future world. Not to mention the problem of global warming caused by its combustion, and of energy security as a result of geopolitical...

Teixeira Pinto, R. (author)
When large amounts of electricity need to be transported for long distances, or when underground or submarine cables are involved, using direct current high-voltage transmission systems is more efficient and cost effective than using traditional high-voltage alternating current transmission. Therefore, the main thesis objective is to study to...

Building-integrated photovoltaic systems (BIPV) are able to improve the energy balance of buildings. However, this improvement can be analyzed quantitatively only if the electricity yield generated by the BIPV system is calculated. This PhD thesis presents a simulation program that calculates the electricity yield generated by BIPV systems,...

Service interruptions have a significant impact on society and therefore the main objective of power system planning and operation is to ensure that they do not happen. Because voltage instability is one of the dynamic phenomena that may result in a system-wide blackout, this type of stability problem has been an important research topic for...

Wind energy accounts for an increasing percentage of the energy supplied to the electricity network. Electricity generation from wind is now cheaper than other renewables and almost cost competitive with other conventional sources of electricity generation. However, this impressive growth is largely due to advances in large wind turbines,...
