Multi-Timescale Volt /

VAR Optimisation in
Smart Distribution Grids

Within an advanced distribution management system , multi-timescale Volt / VAR functionality enhances the efficiency , sustainability , stability and security of a grid . Its impact can be further improved with fast-acting smart inverters and battery energy storage systems .

Competitive Advantage

• Providing predictive control where forecasting uncertainties exist – slow and fast timescale controls are coordinated using two-stage stochastic programming
• Expertise in this area of multi-dimensional optimisation

Impact

• The rapid increase in the integration of intermittent renewable energy sources into existing distribution grids has presented technical challenges , such as voltage rise events
• The multi-timescale operational approach increases the hosting capacity of distribution grids for intermittent renewable energy sources by coordinating the timescales for corrective action across multiple systems – this improves the steadystate stability of distribution grids
