Problem make different sources working together

• without power quality loss
• keeping efficiency as high as it is possible
• keeping costs as low as it is possible
• Electronic power converters give possibility to
  make efficient link between different type of
  sources
• The system of different sources connected to
  DC-link needs to be designed, built and examined
• Power of sources should be at least few hundred
  kW per unit

3
Problem efficient power conversion

• bidirectional AC/DC converters for energy storage
  systems
• AC/DC converters for variable frequency systems
• DC/AC converters working with grid or
  stand-alone
• all the rest you need

4
Strategy

• We would like to find out
• how sources work with power converters
• how sources work together
• how to operate them to minimise costs
• We are going to do this by building and practical
  examining the DC-linked system

5
Work plan

• control strategy design
• remote control system design
• about 2 MW power converters design (DC/DC, DC/AC,
  AC/DC)
• converters construction
• system construction
• system operating examination
• approximately 5 years

6
Partners

• power electronic company(APS Energia Ltd.)
• distribution company
• industry electrical engineering institute (i.e.
  Magdeburg University of Technology, Aachen
  University of Technology)
• budget should be about 1,5 Million for power
  electronic converters and control systems project
