Titel
Online-monitoring and prediction of wind power in german transmission system operation centres
Abstract
Electrical systems must be designed and operated in order to accommodate the changes in the consumption, a trip of a conventional production unit or a fault on a transmission line. Normally, they are able to absorb a certain amount of unregulated and fluctuating production from renewable energy sources (RES), especially wind power. For systems with a high penetration of wind power, the most significant difference is that in addition to forecasts of the consumption, predictions of the unregulated wind power production are also to be prepared. Such predictions are necessary for the Transmission System Operator (TSO) and for players on the power market that owns significant wind power production sites as well. By July 2003, more than 14000 Wind Turbines (WTs) with a capacity of 12,850 MW have been installed in Germany [1]. Windgenerated power provides a noticeable percentage of the total electrical power consumed. This indicates that wind is a significant factor in electricity supply, and in balancing consumer demand with power production. In the control areas of the German Transmission System Operators (TSO) E.ON Netz and Vattenfall Europe Transmission GmbH more than 100 % of the electricity consumption has been covered by wind power at times. This aspect will be distinctly strengthened when the offshore potential in the North and Baltic Seas is developed to the extent that is predicted in many scenarios. A well-established and scientific analysis of the time response of wind power as well as the accurate determination of the current and expected wind power will lead to an improved integration of wind generation into the electrical power system and reduce CO2 emissions sustainable. In frame of governmental and EC funded projects and in co-operation with the German TSOs E.ON Netz, RWE Net and Vattenfall Europe Transmission, ISET has developed a new planning tool to support large scale wind power integration into the electrical energy supply system - the Wind Power Management System WPMS. This tool provides the current level of wind power generation (online-monitoring) as well as the short-term prediction from 1 hour up to 72 hours.
