The German National Meteorological Service has partnered with the Institute of Wind Energy and Energy System Technology (IWES) to better predict renewable energy output.The collaboration of the two parties has led to the development and launch of a new system to help predict the feed of power from wind and solar energy resources, in line with weather conditions.
The system - EnergyForecaster - helps transmission system operators (TSO) to meet grid load demands by providing insight into how much power is and can be generated, according to local media.
[quote]The forecasting service reportedly provides 20 different displays of weather forecasts and alerts for each quarter hour to predict power generation within hours or days.
The partnership falls under the German Meteorological Department led EWeLINE project, which seeks to develop new forecasting products to enhance power generation form wind and solar resources.
The project was kickstarted in 2012 and includes the Fraunhofer IWES and German TSOs Amprion GmbH, TenneT TSO GmbH and 50 Hertz Transmission GmbH, as partners.
Commenting on the development, Dr Malte Siefert of IWES, said: “It’s crucial for us to interconnect both worlds – forecasts of weather and power – more closely than before, tailoring them better to the requirements of the transmission system operators.
“It’s crucial to calculate precisely how the 1.9 million photovoltaic facilities and wind farms operating in the country will convert the weather into electricity,” added Siefert.
Renewable energy storage
The launch of the new forecasting system follows a late May announcement by the global power conversion systems (PCS) company Nidec ASI that it has partnered with German utility STEAG to construct a 90MW energy storage plant in Lünen town in Germany.
The Italian based PCS solutions provider said it has started the development of the system for a secure and efficient storage and conversion of power generated from renewable energy sources into the grid. [How weather forecasting can impact solar diesel hybrid systems].
The plant will consists of Nidec ASI’s energy conversion technologies and LG Chem batteries and is part of the utility’s effort to stabilise the grid by providing TSOs with backup power generated from renewable energy sources.
In addition to the Lunen storage plant, STEAG said it will add in some five more plants in the North-Rhine- Westphalia and Saarland regions.
