INCREASE - INCREASING THE PENETRATION OF RENEWABLE ENERGY SOURCES IN THE DISTRIBUTION GRID BY DEVELOPING NEW CONTROL STRATEGIES AND OFFERING ANCILLARY SERVICES
KOMUNALNA ENERGETIKA / POWER ENGINERING, 7
The INCREASE project is investigating ways to manage renewable energy sources in Low- and Medium Voltage networks, to provide ancillary services towards distribution- and transmission system operators, in particular voltage control and provision of reserve. The project will investigate the regulatory framework, grid code structure and ancillary market mechanisms, and propose adjustments to facilitate successful provisioning of ancillary service, necessary for the operation of the electricity grid.
The project will enable distributed renewable energy sources (DRES) and loads to go beyond just exchanging power with the grid which will enable the system operators 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.
A simulation platform will enable the validation of the proposed solutions and provides the distribution system operators with a tool they can use to investigate the influence of DRES on their distribution network. The solutions will be validated by lab tests, as well as in field trials in the real-life operational distribution network of Elektro Gorenjska (Slovenia), Stromnetz Steiermark (Austria), and Liander (the Netherlands).
The project runs from September 2013 till August 2017, co-ordinator is Gent University

GROUNDS FOR INTRODUCING PERMANENT CONTROL IN
THE TRANSFORMER STATIONS

Electricity consumers are becoming more aware of their rights regarding the quality of electricity. Distribution companies must take care of the uninterrupted supply of electricity, both in terms of ensuring the continuity of supplies and the compliance with the SIST EN 50150. New technologies, used by business users and by households, put distribution companies against new challenges and compel them to ensure the quality of electricity.
In Slovenia the standard EN 50160, which defines 13 parameters of quality of electricity, is used to ensure the quality of electricity and is described in the following paper.
