Optimising Renewables Imports and Exports with Dynamic Operating Envelopes

Optimising Renewables Imports and Exports with Dynamic Operating Envelopes

Australia leads the world in rooftop solar energy adoption, however the capacity of our local distribution networks is limited when trying to safely accommodate rooftop solar. To support the growth of solar and clean energy resources, distribution networks are shifting toward adopting Dynamic Operating Envelopes.

The objective of Dynamic Operating Envelopes is to calculate exactly how much energy can be safely imported from and exported to the grid at all times, and to communicate these dynamic boundaries to clean energy resources. This ensures the safe integration and operation of renewables connected to the grid.

Currently, networks apply static export limits, which define a fixed maximum amount of solar power that a customer can send to the grid based on conservative long-term modelling. Dynamic Operating Envelopes, however, aim to allow more solar to be exported at times where the network can safely accommodate it. Rather than static limits, Dynamic Operating Envelopes change over time based on dynamic real-world conditions such as weather and customer loads. They can be thought of as traffic lights, which allow more renewable power to be exported at certain times, while restricting exports at other times when there is too much solar for the grid to handle.

One of the key challenges in energy management is enforcing Dynamic Operating Envelopes while also coordinating Solar, Batteries, Electric Vehicles, and flexible loads to all work together, which is where Mondo’s Ubi Platform can help. The Mondo Ubi Platform uses advanced forecasting and modelling capabilities to optimise return for customers, ensuring batteries are charged when there are cheap renewables available in the grid and then discharged when the grid needs that power, while enforcing Dynamic Operating Envelopes. This ensures our customers maximise their renewable energy, save on their energy bill and earn more from their renewable energy that is sold back to the grid.
