The interest in energy storage is situated at the core of countries with climate change commitment and renewable energy policies.
Energy storage plays a main role bringing grid stability and electrical availability
Li-Ion technology is the most appropriate technology to solve the mentioned problematic for the following reasons:
- Li-Ion has the capability to respond to electrical curtailments in millisecond time frame, and is able to provide energy during minutes until the grid stability is reached.
- This Li-Ion characteristic is favourable to reduce curtailments in weak grids.
- Li-Ion power technology has a very high energy density, for example a system of ~5MW will need approximately 40 m2 to be installed.
- Li-Ion technology has high efficiency, more than 90%, and thus offers the possibility to use the electricity when prices are more beneficial, increasing the incomes of the traditional business model.
Australia´s energy storage market presents an opportunity for a large addressable market for storage system vendors and developers
Special mention has to be done with South American countries. This is a very interesting market because of the weakness of the current infrastructures and geological characteristics (islands, isolated areas, etc.) and their potential growth
Chess will generate following opportunities and challenges:
• Current distribution: There are many paralleled strings and is critical to accurate an equal current distribution. It is necessary to model the final solution to define and apply the installation procedure.
• To monitor (in local and remote) all the important values, voltage, current, temperature, …, in order to get information and feedback.
• The converters' response time during the different power requirements.
• Communication isolation against Electromagnetic emissions, this type of emissions is critical in this type of installation because of the voltage, current and converter’s frequency.
