Fast Power-Flow Solutions for Future Distribution Grids

Electrical grid's modernization inevitably requires higher integration of renewable energy sources and new technologies to handle their unique features that differ from conventional energy sources. Power generation that is local to the consumption is a new emergent feature when solar energy is harnessed through photovoltaic panels. Consequent to that, radial electrical networks within the distribution grids would have the potential to transform into networks that are more meshed in their topologies. The complexity introduced by such configuration change is compounded by sudden power variability inherent in the solar-based generations. The technology for computationally determining power-flow for such scenarios, to ensure adequate, safe and economic supply, needs new capabilities. In this work, the application of a fast non-iterative power-flow technique to a meshed grid among buildings, based on holomorphic embedding, is validated for the context of Singapore
