Voltage Performance Analysis with Integration of Utility Scale Solar PV Plant in Bangladesh National Grid

Abstract

The aim of this paper is to analyze the voltage performance due to integration of an utility scale Solar Photovoltaic Generation (SPVG) in Bangladesh national grid. Voltage profile in a power system is a major concern for supplying quality power to consumers. Integration of SPVG in a relatively weaker part of a grid may require reactive power compensation to retain acceptable voltage level. In this paper, detailed investigations are carried out to explore the impact of 8 MW SPVG at a 33 kV bus of northern zone of Bangladesh power system. In addition, static voltage stability analysis is executed using continuation power flow method. Afterwards, reactive power compensation is done using capacitor bank to maintain the required voltage to integrate SPVG to the grid. All the simulations are performed based on practical operating scenarios of Bangladesh power system using DIgSILENT PowerFactory software.
