Virtual Power Plant Wind & Solar Power Forecasts

Key technologies for renewable energy integration

Challenges arising from decentralized variable energy production

▪ you need to know the current production of your solar and wind plants

▪ you need to know the future production schedule

▪ you need to control your assets as far as possible

Our solution:


Solar and Wind Power forecasting service

Scope: single parks, portfolios,

balancing areas, market,

rooftop pv (estimate & forecasts)

Horizon: up to 15 days ahead

Resolution: hourly down to 5 minutes

Updates: down to every 5 minutes

Non-availabilities: consideration of outages

Service: 24/7 technical service

Monitoring: access to web portal for

monitoring real-time production

& power forecasts


Grid-related forecasts

With our predictions of weather-dependent power line capacities and grid loads

we support grid operators in their operations and ensure a smooth integration of

volatile feed-in.

Grid-load forecasts

▪ Proprietary methodology to forecast impact of

distributed feed-in on grids (e.g. substations)

▪ Goal: Avoid overload situations and plan maintenance

periods

Dynamic Line Rating

▪ Forecast of maximum current carrying capacity of

power lines based on numerical weather predictions

▪ Goal: Efficient use of weather-dependent ampacity of

overhead power lines


Virtual Power Plant (VPP) for distributed generation and load

▪ Aggregation of distributed energy

units to single portfolio

▪ Connects to unlimited number

of wind onshore & offshore,

solar, hydro, storage systems…

▪ Integrates power forecasts for

connected plants

▪ Monitors current and future power

output (considering outages)

▪ Remote-controls plants to adjust

power output (e.g. in case of grid

congestions)

▪ Direct interface with power

markets


Applications & Business Models with VPP

▪ Data acquisition & monitoring of

current and future production

▪ Control center for grid operators or

plant operators to remote-control

production/ feed-in of renewables

▪ Trading of renewable energies on

intraday and spot markets

▪ Providing ancillary services with

renewable energies

▪ Demand Side Management with

flexible consumers

▪ etc.
