How Can Energy Storage Help the Stability of Future Grids?

EnerSys Webinar

Energy storage is an established technology. Therefore, the dynamic behavior of storage is even more important than its long term capacity. Energy storage needs to be integrated in network-based energy systems, in the electrical grid system, heat and cooling network and gas networks. It can also provide an important contribution to the development and emergence of the Smart Grid concept at all voltage levels.

Power disturbances are a major cost and concern for today’s utilities and industries as they struggle to cope with growing demand, an aging infrastructure and the challenges of incorporating renewable resources. In fact, over the past 20 years, blackouts have increased 124%. Frequent and potentially destructive disturbances from power grids are also resulting in voltage sags, brownouts, over voltage conditions and power outages. Stabilizing the power grid means preparing for voltage regulation, frequency regulation, ramp control and peak shaving. Increasingly, utilities are discovering significant benefits through the integration of large battery systems into their power grid architecture

In time when renewable energy sources as part of the electricity network is higher than ever before we start to see multiple implications caused by voltage drops or frequency variations. This may have a significant impact, for example, to sensitive process industry or even actual grid balance. Correctly located storage with proper technology selection might be a solution to overcome some of these challenges.

Existing energy storage offerings currently on the market vary from relative small electrochemical storages up to MWh scale CAES (Compressed Air Energy Storage) and Pumped Hydro storages. The crucial thing for DSOs and TSOs is to understand the application they need to support it with. Is it then load profile, reaction time, frequency of the events for example, but all these should affect storage (technology) selection to maximize the benefit resulting in the best possible reliability and availability of the grid.

EnerSys is the global leader in stored energy solutions for industrial applications. For over 100 years, EnerSys and its predecessor companies have been manufacturers of industrial batteries which are used in applications such as telecom, utilities, aerospace and defense, forklifts, industrial vehicles, rail equipment, cars, and boats.
