Abstract:
Sudan is a vast country with grid-power limited to urban areas. The network experiences power cuts and blackouts occasionally. In this context, water pumping in rural areas relies on diesel driven systems which, in turn, faces fuel shortage and maintenance problems sometimes extending to long periods. PV solar pumping systems represent, a reliable alternative with very low maintenance requirements. Such systems suit the water supply requirement in situation where the need is not high. This makes them suitable for rural village water supply as well as small scale farming practiced in such areas. This paper investigates the suitability of PV pumping to rural needs with respect to Sudan climate. Also, it is intended to review the current operational PV pumping system installed so far.

Abstract:
The National Grid of Sudan represents a system that is unique both in its topological layout and operational practices. While the current generation capacity does not exceed 500 MW divided almost equally between Hydro and thermal sources, it is surprising that such a small system is marred by a number of operational problems. The problems can be categorized in descending order with respect to their severity as transmission difficulties, hydro generation availability, stability problems, transmission and distribution losses and primitive monitoring and control functions. Some of these problems have been addressed in the recent years by a limited number of international firms and local advisors, and plans for transmission reinforcement and hydro reservoir enlargements have already left the drawing table and entered the execution phase. This paper discusses to what extent would the system performance be expected to improve on completion of such plans and whether more needs to be done and the primary areas targeted for enhancing the stability, security and reliability of the system.

By Amel Sheikheldin Mohamed Abdulla
Presented by Dr Yousif H. Ahmed (SESUKI's Vice-chairman and Academic Secretary)
Abstract:
Houses, contributing more than 65% of the built up areas in developing countries, are key consumers of energy and natural, non-renewable resources. This paper explores the prospects of designing ecological and energy efficient (eco-efficient) dwellings within the urban context of Khartoum City. The paper investigates the efficient utilization of renewable energy and the conservation of natural resources, through the architectural design of dwellings. The main areas of investigation are: a) Dwelling Compatibility with the Climate and Natural Environment; b) Choice of Building Materials and Construction Techniques; c) Utilization of Solar Energy & Photovoltaics; and d) Water Conservation & Recycling Technologies.
