Microgrids in interconnected and islanded modes - WG 2018-3

TECHNICAL REQUIREMENTS FOR THE OPERATION OF MICROGRIDS IN BOTH INTERCONNECTED AND ISLANDED MODES
 

Background

Microgrids may offer a number of important advantages for the end-user and for the network utility. They have an impact on the way distribution systems are controlled, operated and protected. Proper technical solutions have to be designed to allow microgrids to bring the expected benefits to the various stakeholders, while making sure there is no negative impact on the overall cost base, power quality and person safety.
Specific technical challenges may arise with microgrids mostly or fully based on power electronics interfaced distributed generators.


Scope

The working group will cover issues related to both isolated microgrids (i.e. those that only function in an islanded mode), and embedded microgrids (i.e. those which can be operated either while connected to the surrounding power system or while islanded)

The working group will investigate the following issues :

  • Frequency control and voltage regulation,
  • Protection and safety issues, including network protection solutions for microgrids with low short circuit currents,
  • Black start capabilities
  • The design of control systems able to face the requirements of both islanded and interconnected operation and during transitions between the two modes
