Apart from cost, the net production of energy is the most important factor in evaluating the feasibility of producing renewable fuels from woody biomass. Unlike sugar, the effort required to make woody materials fermentable is considerable, and has been a major barrier to the use of such...

Apart from cost, the net production of energy is the most important factor in evaluating the feasibility of producing renewable fuels from woody biomass. Unlike sugar, the effort required to make woody materials fermentable is considerable, and has been a major barrier to the use of such...

The liberalisation of the West European electricity and gas markets, technological developments in power technology and environmental policies are expected to stimulate continued strong growth in power generation gas consumption. This paper examines the importance of three frequently disregarded...

This comment discusses in more detail one of the primary messages in the paper by David Humphreys and Keith Welham, namely the fundamental shift in the steam coal industry away from security of supply concerns and national focuses towards an international and cost-driven perspective. On the...

The Southern African Region has been experiencing power shortages due to increased demand with static power supply as a result of limited investment in both generation and transmission infrastructure across the region. This paper discusses how the power utilities in the region plan to cope with...

In this paper, the protection issues related to distributed generation in distribution networks are considered. Especially, the requirements for the generation unit's protection are discussed. A new graphical approach is used for finding the unambiguous limits of operation. The method is based...

This paper presents a new approach to solve the short-term unit commitment problem using genetic algorithm-based simulated annealing method for utility system. The objective of this paper is to find the generation scheduling such that the total operating cost can be minimised when subjected to a...
