PARTIAL SHADING AND ITS IMPACT ON PHOTOVOLTAIC PANEL PERFORMANCE

This experimental study investigates the impact of partial shading on the performance of photovoltaic (PV) solar panels, specifically comparing mono-crystalline and polycrystalline types. Three different covering materials with varying transmittance levels—white leaf, tree leaf, and transparent paper—were used to create shading conditions. The shaded cell area varied by 20%, 50%, and 100%, and

MINIMIZATION OF THE IMPACT OF THREE PHASE FAULTS ON THE VOLTAGE PROFILE OF THE NIGERIA 330kv TRANSMISSION NETWORK USING CAPACITOR COMMUTATED CONVERTER-BASED HIGH VOLTAGE DIRECT CURRENT (CCC-HVDC)

This research paper presents the minimization of the impact of three phase fault on the voltage profile of the Nigeria 330kV transmission network using Capacitor Commutated Converter-based High Voltage Direct Current (CCC-HVDC). Power system disturbances caused by loss of generation, switching actions, change in loads, and majorly faults lead to various degrees of voltage instabilities.
