Outline of Research at the Start

To achieve the goal of this study, LGU initiatives will be extracted from their respective websites and used to model solar PV growth. An energy model will be created, and several deployment scenarios that could reduce the impact on transmission lines will be evaluated to identify the country’s optimal use of transmission lines. The results of this research are expected to reduce the financial burden on transmission lines by promoting energy decentralization through the optimal distribution of solar PV deployment.
