Toshiba ESS conducts trials on batteries to enhance renewable energy generation

Toshiba Energy Systems & Solutions Corp (Toshiba ESS) and Next Kraftwerke Toshiba Corp (TNK) have announced the successful completion of a demonstration project focused on improving renewable energy power generation forecasting and reducing imbalances through the use of storage batteries. The trial involved more than 200 energy resources, which included solar and wind power, as well as storage batteries. The project utilized the REBSet platform, which is an innovative renewable energy balancing system. The results of the trial were promising, with Toshiba ESS reporting up to 70% reduction in renewable generation imbalances through the use of cloud-controlled storage batteries.

As part of the trial, the teams sought to improve the accuracy of solar and wind power forecasts by developing novel forecasting methods that relied on frequent updates that were closer to actual power generation. The teams also used charge/discharge plans for storage batteries, which were based on generation forecasts and day-ahead market price forecasts, to increase the profitability of renewable energy aggregators.

The consortium that conducted the project included 14 renewable energy aggregators, including Toshiba ESS, and nine partner companies. The Japanese Ministry of Economy, Trade and Industry also provided support for the project. Overall, the trial reflects an important step towards improved renewable energy power generation forecasting, which is critical to the widespread adoption of renewable energy sources, particularly given the variability in power generation that is characteristic of renewable energy systems.
