“Battery-based energy storage is critical to increasing the share of renewables and decarbonizing island power systems. Fluence is proud to have collaborated with Siemens to support EDA in their drive to innovate and lead the energy transition,” said Paul McCusker, SVP & EMEA President at Fluence.
The Azores have nine isolated autonomous energy
systems with great potential for renewable energy, mainly from wind, solar, and
geothermal sources. The challenge was to find the right balance between energy
production and consumption in the face of sharply fluctuating feed-in and
demand cycles. The project team worked with the customer with the goal of
providing a more secure power supply for island residents while steadily
increasing the share of renewables in the electricity mix to up to 50 percent.
Since 2018, based on
their knowledge and experience in the field of Battery Energy Storage Systems
(BESS), the consulting team of Siemens Power
Technologies International (PTI) has performed
several BESS sizing and integration studies for EDA. These studies aim to find
the solution that is best suited technically and economically, assess
viability, and specify the sizing and technical requirements
as a basis for tenders. During the implementation stage, PTI is supporting EDA
with BESS dynamic and integration studies. Different sets of scenarios are
considered in order to evaluate BESS response and ensure reliability, stability
and safety of the entire electrical system.
The Spectrum Power
Microgrid Management System (MGMS) from Siemens deployed on Terceira ensures
optimal interaction between all power generation assets, battery storage and
power consumption. It enables real-time monitoring and control of the entire
infrastructure as well as hourly or daily forecasts regarding production,
consumption, and storage use. These forecasts are based on a variety of data,
including weather information and historical data. The software allows the
operator to manage and optimize the complete microgrid.
The 15-megawatt battery-based storage system
supplied by Fluence is one of the largest stand-alone projects of this type (on
an island) in Europe. Fluence’s Gridstack system will deliver grid forming,
reactive power and short circuit capabilities. This allows excess renewable
energy to be captured and then fed back into the grid when not enough power is available
to meet demand, reducing the production of energy from fossil fuel sources. The
modular battery storage system can be expanded as needed.
