The Singapore Energy Market Authority’s ‘Intelligent Energy System’ pilot project is creating a ‘living laboratory’ for smart grid systems.
By Dr Denis Gross
Conventional electricity grids pose various challenges, not least of which is the inherent wastage in centralised generation models due to losses in conversion, transmission and distribution. Industrial and commercial users are generally ‘savvy’ about consumption, and for the most part their usage patterns are steady and controlled. Domestic consumption, however, tends to display high volatility, with sharp peaks and troughs. These challenges alone might underpin the case for a ‘smart grid’. Add rising electricity prices, the need for energy security, growing levels of generation of intermittent renewable energy and the anticipated growth of electric vehicles, and it becomes clear that traditional grids must change if the world is to avoid energy rationing and power outages.
