This research project aims to address and solve one of the most paramount and pressing topic the Singapore power grid operator and regulators face in the next decade: how to ensure a stable and reliable grid operation with an increasing share of electricity generation coming from widely-distributed, intermittent renewables, especially solar photovoltaics (PV). The goal of this research is to analyze the Singapore Power grid for its suitability for a large share of energy supply from intermittent generation. The project will identify and address the potential for optimisation in system design, components and system management, and to develop suitable innovative solutions for the required operations management, as well as for balancing demand and supply during times of intermittency.
