Grid code compliance for grid-connecting a PV system to an existing facility in Singapore

Grid-connected Photovoltaic (PV) system is a most promising renewable energy source in Singapore. This paper presents how Singapore ensures a safe and secure power system network on connecting a PV system in parallel to the main power grid. This research project was carried out under the supervision of a registered Professional Engineer (PE) from Singapore together with an academic Professor. A scenario was setup in this research based on a client with an existing facility who wished to install a PV system at their premises of 600m2, in parallel to the power grid. In order to achieve that, research on Singapore grid code is mandatory so as to comply with it. A feasibility research has been done for satisfying the expectations of the client based on the rules and regulations of Singapore power industry. ETAP has been used for the analysis of technical parameters. Based on the comprehensive studies and analysis, it has been reflected to proceed with the installation of the PV system to low tension of the grid in parallel with the Singapore power grid.
