The textbook presents a brief outline of the basic engineering in design and analysis of PV - diesel hybrid power system. The study has been taken from the point of view of introduction, literature review, pre-design preparation, system design and simulation, simulation results and discussions, conclusions and recommendations. Most of electrical power supplied in Darfur regions are mainly generated by diesel generator units isolated from the national grid. Although those generating units has also received a complete maintenance overhaul, However, capacity problems, such as generator...
