Hybrid Photovoltaic-Wind system as power solution for network operators in the D.R.Congo

Abstract: Escalating diesel prices and to a lesser extent a desire to reduce global warming gasses, have caused most mobile operators to seriously start looking at alternatives to standard diesel electric set on remote sites. This paper investigates the possibility of using a hybrid Photovoltaic-Wind power system to supply Base Transceiver Station load in the Democratic Republic of Congo. The Hybrid system has been sized using “The most unfavourable month method”. The simulation are performed using the Hybrid Optimization Model for Electric Renewable (HOMER), with wind speed, the solar radiation and the system components costs and technical data as inputs; and then compared with those of a diesel generation‥

Modeling and simulation of Umlazi suburb of Durban municipality network (South Africa)

Abstract: The main focus is to model and simulate the portion located in the ULMAZI suburb of the Durban municipality network incorporating FACTS devices, in order to improve the stability of the whole network. Instead of doing modeling and simulation for each generator while they all have the same characteristics, a simplified dynamic model of a power system is used in this study, named Single Machine Infinite Bus (SMIB) power system. This model consists of a single synchronous generator connected through a parallel transmission line to a very large network which is UMLAZI approximated by an infinite bus. For the design purpose, the model of example power system which is a SMIB power system installed with the TCSC device and SSSC connected in series is developed in MATLAB/Simulink. Simulation results in terms of power system responses prove the enhancement of power system performance and fast damping of power system oscillation.
