Innovation pilot - Grid support battery

Posted by Karolis Mirinavičius

In highly regulated energy industry, electricity Distribution System Operators (DSO) are obliged to compile with existing grid codes and have to maintain specific quality voltage standards for all customers, either they are located in urbanistic or rural areas. For this reason, Ignitis group DSO “Energijos Skirstymo Operatorius” (ESO) together with Ignitis Innovation Hub has launched a pilot project to test grid support battery systems in distant rural locations with weak low voltage grids.

The aim of the project is to evaluate the technological feasibility of grid storage solution to delay costly and time-consuming grid reconstruction. Grid storage is seen as an opportunity to tackle voltage quality problems at the end of the long 2-4 km low voltage power lines. The 5kW unit with 10 kWh of storage in this particular case is used as flexible asset in peak-shaving mode.

The first battery test we tested have stopped - the battery became obsolete to solve customer problems. However, we continued to refine our vision and the second test has improved - it is possible to connect one or two users to it and thus expand the relevance of the solution, test the technological limits.

Innovation expert Karolis Gesevičius sends us greetings from the fields of Lithuania and presents implemented innovation - power maintenance system, otherwise, the battery.
