The significant rise in distributed renewable energy sources has placed an enormous burden on the secure operation of the electrical grid, impacting both the transmission system operators (TSOs) and distribution system operators (DSOs). The massive increase of the intermittent DRES in low (LV) and medium (MV) networks has led to a bidirectional power flow which raises the urgent need for new operational and control strategies in order to maintain the ability of the system to provide the consumers with reliable supply of electricity at an acceptable power quality level.
Technically, INCREASE will focus on how to manage renewable energy sources in LV and MV networks, to provide ancillary services (towards DSO, but also TSOs), in particular voltage control and the provision of reserve. INCREASE will investigate the regulatory framework, grid code structure and ancillary market mechanisms, and propose adjustments to facilitate successful provisioning of ancillary services that are necessary for the operation of the electricity grid, including flexible market products.
INCREASE will enable DRES and loads to go beyond just exchanging power with the grid which will enable the DSO to evolve from a congestion manager to capacity manager. This will result in a more efficient exploitation of the current grid capacity, thus facilitating higher DRES penetration at reduced cost. Because of the more efficient use of the existing infrastructure, grid tariffs could decrease, potentially resulting in a lower cost for the consumers.
The INCREASE simulation platform will enable the validation of the proposed solutions and provides the DSOs with a tool they can use to investigate the influence of DRES on their distribution network. The INCREASE solutions will also be validated (i) by lab tests, as well as (ii) in three field trials in the real-life operational distribution network of Stromnetz Steiermark in Austria, of Elektro Gorenjska in Slovenia and of Liander in the Netherlands.
