Wind Tutorial

Ancillary Services and Wind Power Plants: Status and Experiences

On Tuesday afternoon, 16 October 2018 (14:00 – 18:00), prior to the start of the Wind Integration Workshop, a tutorial will be held by international experts on “Ancillary Services and Wind Power Plants: Status and Experiences”.

Online booking is now closed! You can still purchase a tutorial ticket on-site in Stockholm.

High share of renewables in the power system can only be achieved if wind power plants also offer ancillary services, e.g. voltage control, balancing services and frequency control. Within this tutorial technical solutions and practical experiences are presented and discussed.

Lecture 1: Balancing Response with Wind Power Plants
Andreas Linder (ENERCON, Germany)

Control Reserve as a System Service has the important role to stabilize the grid / the frequency whenever an incident occurs in the grid. As of today 3 GW of Primary Control Reserve are necessary in Continental Europe to compensate the first loss of generation or consumption. Further Control Reserve products help longer-lasting incidents. Diverse remunaration schemes are in place to give the System Responsible Parties access to adequate Control Reserve which also gives owners of Power Plants access to a source of revenue. How may Wind Energy be used to offer Control Reserve? What technical solutions exist and which are possible? Which regulatory and technical boarders exist that hinder Wind Energy from offering Control Reserve? This talks wants to give answers to these questions along with presenting finished and actual pilot and research projects.

About the lecturer:

Andreas Linder, born in 1984, studied Industrial Engineering at KIT Karlsruhe, specialized in renewable energies, did his Diploma thesis within the Smart Grid project “MeRegio” at ABB Mannheim and works since 2012 at ENERCON in Bremen within the Sales – Grid Integration team, elaborating the grid integration of wind energy in general and in particular specializing in SCADA and Control Reserve.

Lecture 2: Inertia Response with Wind Power Plants

Nicholas Miller (HickoryLedge, USA)

Inertia-based controls for wind turbines provide an opportunity to help address concerns associated with the decline in synchronous inertia and displacement of traditional sources of frequency sensitive generation.  This lecture will examine the fundamental enabling technology for frequency sensitive controls that depend on turbine inertia. Topics will include variations in control philosophy; discussion of why these controls are not exactly the same as synchronous inertia; examples of system performance impacts; and review of some emerging grid requirements.

About the lecturer:

Nicholas Miller is Principal at HickoryLedge and a retired Senior Technical Director from GE Energy Consulting. He has over thirty years of experience on integration of new technologies into bulk power systems. He has lectured on Wind and Solar Power integration to governments and institutions in more than two dozen countries. He holds twenty US patents for wind or solar technologies, and power control devices. Nick is a Fellow of IEEE, New York Professional Engineer, and has authored over 150 technical papers and articles. He holds a B.S. and M.Eng. in Electric Power Engineering from Rensselaer Polytechnic Institute, Troy, New York, received in 1979 and 1980.

Coffee Break

Lecture 3: Renewable Energy and Ancillary Services in Spain
Juan Julián Peiró Peña (Red Eléctrica de España, Spain)

Firstly, the presentation gives an overview of the Spanish Electricity System and its main characteristics. It shows also the specific Control Centre for Renewables (CECRE) and the great level of observability and controllability reached for renewable energies in Spain. Further on, the presentation gets deeply in which is the actual situation of ancillary services: last regulatory changes, mandatory prequalification tests to participate and real participation of renewable energies. Lastly, we will talk about the necessary coordination to avoid impact in congestion management from the units participating in balancing markets.

About the lecturer:

Juan Peiró works from 2008 in the Electrical Control Centre of REE (Spanish TSO) focusing on power system stability, voltage control and renewable, cogeneration and waste large-scale integration. He is participating as well in the commission of the Biscay Gulf HVDC interconnector between Spain and France. Juan holds a MSc in Electrical Engineering from Comillas University. He did his master thesis about power system stability of the future European Supergrid in Chalmers University, Sweden. Nowadays, Juan is a lecturer of the European Master in Renewable Energy Research coordinated by CIRCE and an associate collaborator of Comillas University as a lab teacher of Electrical Power Systems Analysis.
