Description

To meet the European 20-20-20 targets, the share of renewable energy needs to be 20% of the electric energy demand in 2020. This ambitious objective can only be met if the number of distributed renewable energy sources (DRES) at the low voltage (LV) electric distribution grid will significantly increase and large wind or solar plant farms will be installed at the medium voltage (MV) level.

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 systemand the distribution system operators. The massive increase of the intermittent Distributed REnewable Sources (DRES) in Low Voltage (LV) and Medium Voltage (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 consumers with reliable supply of electricity at an acceptable power quality level and cost. INCREASE wants to focus on how to manage renewable energy sources in LV and MV networks, provide ancillary services towards Distribution System Operators (DSOs) but also towards Transmission System Operators (TSOs), in particular voltage control and the provision of reserve.

Five scientific and eight industrial partners are participating in the new ambitious research project INCREASE (“Increasing the penetration of renewable energy sources in the distribution grid by developing control strategies and using ancillary services”) which aims to solve these problems with innovative three-phase grid-connected inverters and 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.

INCREASE investigates the regulatory framework, grid code structure and ancillary market mechanisms, and proposes adjustments to facilitate successful provisioning of Ancillary Services (AS) necessary for the electricity grid operation, including flexible market products. It enables DRES and loads to go beyond just exchanging power with the grid which will enable the DSO to evolve from congestion to capacity manager. This will facilitate higher DRES penetration at reduced cost. The simulation platform will enable the validation of the proposed solutions and provides a tool for the DSOs to investigate the DRES influence in their network. Not only by lab test at TU/e and at Lemcko (UGent), but also real field trials in Austria, Slovenia and the Netherlands will validate the INCREASE solutions.

The aim of the project is to develop control strategies, test them and assess options to provide ancillary services.
