Main purpose
The Hungarian demonstration main purpose is to illustrate the operational capabilities of a mobile electricity storage with an improved DLC (Direct Load Control) system to allow for more planned flexibility and to make PV generation integration more cost-effective.
Zánka is a holiday spot located near Lake Balaton with very high line load overnight in the summer. The grid is therefore approaching the line limit due to the overnight peak load occurring in the summer season. Additional requested PV plants cannot be connected to the MV (due to the voltage change rule stated in the Distribution Code). In this area the grid requires a solution to reduce both the peak load and the voltage change due renewable generation.
Implementation
Within the IElectrix project the following use case scenarios will be implemented and tested in Zánka:
- Evaluation of business cases and benefits of integrating mobile battery systems into networks that would otherwise require reinforcement.
- Evaluation of the possible flexibility within the network, the operation of the current DLC system and the implications on customer behaviors and the potential benefits of more sophisticated load control.
