Nottingham Energy Optimisation

Energy Management – City of Nottingham

The Challenge

The City of Nottingham aims to maximise the use of locally generated renewable energy to cut the carbon emissions and costs associated with charging electric fleet vehicles, as well as reducing peak demand by using vehicles for short-term storage. This requires an energy management solution which integrates the renewable energy sources, the V2G chargers and battery.

Energy dashboard

Energy managers have continuous insight in the performance of solar power generation, the state of the electric fleet chargers, the battery charge state and the financial and carbon savings reached by using an optimisation strategy. The insights page is used to create a personalised single page view to monitor attributes like local energy, self consumption or saved costs.

Insights on the go

The mobile app allows energy managers or maintenance to evaluate the system performance at any time. They receive notifications by the system in case of malfunctioning or uncommon behavior as defined by rules. Once evaluated, they can take action immediately. Notification rules can take into account whether staff is on site or not.

Smart Optimisation

The system forecasts solar power generation, consumption and electricity pricing for the upcoming 24 hours. It’s used to define the optimal charging and discharging cycles for the battery. In addition, it uses the vehicle storage capacity, keeping in mind the minimum vehicle mileage throughout the day as set by the fleet manager per fleet category.

Connected Sources

Solar panel power meters, the vehicle to grid chargers, and the battery storage system are all connected to the energy management system. Pricing data from the supplier as well as relevant weather data is added to accommodate the predictions, while the outcome of the running optimisation routine is translated into charging and discharging commands and requested power setpoints.

Energy Management

Energy management requires monitoring of energy generation, energy consumption, and short-term storage systems, and controlling them to strive for maximum financial benefits or carbon savings.

OpenRemote manager 3.0 enables connecting energy systems and run forecast and optimisation routines, taking into account the set targets, the network mode and capabilities of the connected assets.
