STRATEGIES FOR AN EFFICIENT INTEGRATION OF WIND POWER CONSIDERING DEMAND RESPONSE

Two recently published studies are addressing impacts of wind power on the German and the Austrian power system [4, 5] respectively. In [4] among other issues of wind power integration additional requirements for balancing power up to the year 2015 and an installed capacity of 36 GW are analysed respectively. With the increasing penetration of wind power, a maximum of 19.4 % and an average of 9 % of the installed wind capacity would have to be added to existing positive balancing power. For the additional negative balancing power required, the corresponding values are 15.3 % or 8 % on average. In [5] additional reserve requirements are assessed for an installed wind power capacity of up to 1.7 GW and corresponding cost are estimated based on historic market prices for balancing power in Austria in order to forecast future expenditures for the Program Responsible Party (PRP) concerned. Additional balancing power requirements are ranging from 19 to 29 % of installed wind power capacity depending on the accuracy of wind power forecasts. Future annual balancing cost are indicated in the range of €75m to €105m and 22 to 31 €/MWh(wind) respectively.
