Impacts of increased photovoltaic panel utilisation on utility grid operations : a case study

Renewable energy is starting to be used as the panacea for solving climate change or global warming problems. Therefore in the starting of 21st century, government, utilities and research communities are working together to develop a climate-friendly power generation systems for a sustainable society by increasing large-scale energy generation from renewable energy sources. However, due to the intermittent nature of renewable energy sources creates a number of potential challenges in integrating renewable energy with the existing grid. Harmonic distortion, voltage fluctuation, voltage management, demand assessment, and load rejection are the major potential issues concerning the application of photovoltaic-distributed generation. This paper develops a model using PSS SINCAL to investigate the impacts on integrating photovoltaic panel on the utility grid.
