Multi-Timescale Volt/VAR Optimisation with Battery Energy Storage in Smart Distribution Grids

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

Competitive advantage

  • Providing predictive control where there are forecasting uncertainties. Slow and fast timescale controls are coordinated using two-stage stochastic programming
  • Expertise in this multi-dimensional optimisation area

Impact

  • The rapid increase in the integration of intermittent renewable energy sources into existing distribution grids has brought 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, and improves the steady-state stability of distribution grids.

Successful outcomes

  • Proven advantages on simulated distribution feeders including IEEE benchmarks

Capabilities and facilities

  • Tools, software and real-time simulation capability
