Assessment of Revenue Potentials of Ancillary Service Provision by Flexible Unit Portfolios

Stephan Koch    ETH Zurich, Power Systems Laboratory, Physikstrasse 3, 8092 Zurich, Switzerland

Abstract

In this chapter, an economic evaluation of frequency control provision (primary and secondary control) by flexible unit portfolios, also referred to as virtual power plants (VPPs), is presented. VPPs consist of generators, energy-storage units, and controllable thermal loads. This investigation uses the previously developed power nodes modeling framework (PNMF). Time simulations over parameter ranges are undertaken so as to determine the control potential provided by two benchmark portfolios. Ancillary service market data from Switzerland ...
