As wind energy becomes a larger portion of the world’s energy portfolio there has been an increased interest for wind turbines to control their active power output to provide ancillary services which support grid reliability. One of these ancillary services is the provision of frequency regulation, also re­ ferred to as secondary frequency control or automatic generation control (AGC), which is...

With the aggregation of distributed generators and loads, a Virtual Power Plant (VPP) can participate on electricity markets and provide ancillary services. This paper describes technological control capabilities of distributed energy resources (DER) to provide future ancillary services for distribution and transmission network operation. The analysed future ancillary services comprise frequenc...

Batteries can be used to provide ancillary services, such as primary frequency response. However, their energy capacity is limited. Therefore, set-point adjustments are necessary and the energy for this has still to be provided by power-plants that do not face energy constraints. This paper investigates various aspects of and potential benefits for power system operation and stability, if energ...

The current power systems, namely the low voltage distribution networks, have been suffering considerable changes in recent years. What appeared to be innovation trends nowadays due technological advances and manufacturing cost reduction has become new reality coming Thus, growing trend of generation by renewable sources posed challenges opportunities. Furthermore, wide installation “smart mete...

In this paper the problems of market monitoring and control of ancillary services of a future energy systems are presented. We envision that future system operation of electric power systems will evolve into completely unbundled ancillary service markets that are governed by spot price signals. The grid operators need to acquire ancillary services through competitive markets for control of the ...

The flexibility provided by prosumers is recognized as a key element for the management of electrical grids, in particular distribution changing scenario electricity generation and consumption. useful to Distribution System Operators (DSOs) strongly local, it necessary identify busses grid where can be usefully service requested DSO. For this purpose, concept perimeter adopted; defined set such...
