VATES. Optimal operation of power systems with consideration of production forecasts in systems with high wind and solar penetration.

Abstract

From 2010 many countries are changing theirpower generation mix from hydro and fuel-fired generatorsto hydro, wind and solar energy. In Uruguay's case, in thefirst quarter of 2017, the installed wind capacity exceededthe average energy load. Uruguay is an example of a workingsystem with a great amount of Variable Energy Resources(VER).This work shows how the optimal operation of thesystem is programmed on a weekly, daily and hourly basis todeal with the VER. The way the forecast of the wind, solarand hydro resources availability are considered and howthese uncertainties are used to generate a Spot Signal Price(SSP) that may be used to implement a Demand Responsepricing scheme is shown. The   developed   tool   is   called   VATES   and   it   isrunning continuously on ADME's servers. The forecast ofthe dispatch for the next 72 hours is continuously available athttp://vates.adme.com.uy
