“Batteries will play a central role in accelerating renewable energy deployment”

By Mari Kristine Buckholm, Smart Innovation Norway 13. April 2018

New battery technologies are expected to offer higher energy density, faster charging, extended lifetime, and lower cost – which will be demonstrated in the INVADE pilots.

As the INVADE project seeks to integrate electric vehicles and batteries to empower storage in distribution grids, the status battery technologies and prices is worth having a look at.

In general, lithium-ion battery technologies have reached a commercial phase. There are lots of battery manufacturers and system integrators, who provide battery packs or complete energy storage systems.

Declining prices

“With current technologies, the performance is good and the cost is reasonable for many business cases. However, the technology is not fully matured yet. This can be seen, e.g., in lack of standardized products and in rapid decline of prices,” explains Ari Hentunen, Research Scientist, DSc (Tech), at VTT Technical Research Centre of Finland Ltd.

He reveals that the current prices of battery packs and complete energy storage systems for stationary applications are in the order of 600 $/kWh and 1000 $/kWh, respectively. The prices have fallen on average 10% annually and are expected to further decline at a lower rate.

“The levelized cost of stored energy is decreasing as a result of lowering prices and improvements in technology, especially in improvements in cycle life and calendar life,” Hentunen points out.

Batteries in INVADE

The VTT research scientist emphasizes that batteries can provide the flexibility that future electricity systems will need to balance the fluctuating generation of solar and wind energy.

“Batteries will play a central role in accelerating renewable energy deployment,” he states. Which is why the use of batteries as flexibility sources will be demonstrated in the INVADE pilots.

“Lithium-ion battery is a versatile energy storage technology that can be used in a wide range of applications from fast-acting power quality to daily energy storage,” explains Hentunen.

Developing our future society

As huge amounts of lithium-ion batteries are needed in the ongoing shift from the use of fossil fuels towards sustainable transportation and renewable energy production, it is important to develop battery technologies even further.

“For example, the battery technologies need to be improved for large-scale adoption in transportation and storage,” notes Hentunen. He adds:

“New battery technologies are expected to offer higher energy density, faster charging, extended lifetime and safety, and lower cost.”

@INVADEH2020 : In the INVADE project, a central delivery is the cloud-based Integrated INVADE platform, which will be used by the Flexibility Operator to manage #flexibility from flexibility providers and offer this to flexibility customers. It is crucial to specify how data can be sent to and from the Integrated INVADE platform through its communication platform API pilot by Pilot.

@INVADEH2020 : Communication technology is not only what type of data will be shared between different users, but also identifying the steps to follow to achieve a total and bidirectional integration between cloud platforms and field devices and systems at consumer’s sites, taking also into account that it should be scalable enough to accept new devices in a simple way. In INVADE, the protocols and standards of the different equipment and systems which can be installed at pilot sites have been defined, as well as all types of existing communications both with the cloud system for flexibility services, as well as between the devices themselves.

@INVADEH2020 : Deliverable D5.3 provides a simple model for flexibility operation and planning to serve distribution system operators (DSO), balance responsible parties (BRPs) and Prosumers. This is a simplified model that will be initially implemented in the integrated INVADE Platform (IIP). This report contains the first version of flexibility management allocation and operation algorithms. The first part of D5.3 contains a description of the flexibility management algorithms that is used in the daily operations of the Integrated INVADE Platform (IIP). First, the basic modelling concepts are proposed and discussed with regards to flexibility from stationary batteries, loads, EVs and flexible generation. This is followed by a discussion of possible approaches for handling uncertainty, including the length of the planning horizon and how detailed the time resolution should be. Finally, the simplified version of the mathematical formulations of flexibility assets is given. A key finding in the document is that the way to model flexibility and how much value that can be extracted from the flexible sources, are tightly connected to the amount of information that is available The second part of D5.3 focuses on models and algorithms for optimal decision on battery size and placement by considering the operational constraints. A simplified planning strategy that leverages the control strategies of battery charging and discharging to find the optimal location and size of batteries in distribution system is presented from both prosumer and DSO perspectives. This is complemented with illustrative examples on battery-PV sizing analyses for prosumers. You can access D5.3 at https://h2020invade.eu/deliverables/ ( - 2 weeks ago)
