BESS Engineer Internship

The opportunity

The internship aims to develop new functionalities for the tool used by Hitachi Energy to configure Battery Energy Storage Systems (BESS) and perform techno-economic analysis for several grid codes of different regions.

How you'll make an impact

The selected candidate will work on the Power Store Selector tool developed by Hitachi Energy, analyze the code written in Matlab® and improve it in order to make the User Interface more user friendly and add new functionalities to the tool.

This tool is used by the Sales team, so it has to take into account all the main project requirements and product features. Some of the additional functionalities to be implemented are:

-      BESS design with mixed configurations

-      PCS Power derating due to the temperature, altitude.

-      Grid code compliance.

The selected candidate will first become familiar with the tool and the its code, running multiple simulations for different scenarios. Then he/she modifies the code and at the end will test it with the same scenarios to verify the improvements.

During the internship, in order to reach the objectives, the selected candidate will perform some BESS market analysis to get costs and product features which will be used as input of the PSS tool. Moreover, he/she will use also the Hitachi Energy Power Converter sizing tool to check the capability of Hitachi Energy products for different grid codes.

Your background

  • Completed or ongoing Master Degree in Electrical/Electronic/Energy Engineering;

  • Fluency in Italian and English;

  • Interest for BESS sector.

  • Proactivity, willingness to learn and ability to work in a fast paced team are required.
