Lyngby, Denmark 1 Introducton The sngle-area verson of the IEEE Relablty Test System [1] s updated to a verson that can be readly used for electrcty market and power system operaton studes. The 24-bus power system was updated based on data from [1]-[5]. Addtonally, t s properly modfed to accommodate sx wnd farms n order to enable the use of the power system n case studes wth hgh renewable energy penetraton. 2 System Descrpton The 24-bus power system s llustrated n Fgure 1.

3 2.1 Unt Data Tables 1-2 present the generatng unts data of the power system. The generatng unts offer a sngle block of energy, up and down reserve capacty. Table 1 provdes the techncal data of generatng unts and Table 2 provdes the costs and ntal state of the generatng unts at the begnnng of the schedulng horzon. The data s based on [1]-[5].

A negatve one shows the tme perods that the generatng unt has been offlne at the begnnng of schedulng horzon. 2.2 Load Data In Fgure 2, the load profle s llustrated. Table 3 provdes the total system demand per hour and Table 4 presents the node locaton of the loads, as well as the load at each node as a percentage of the total system demand. The load data s based on [2]. C ī C su P n U n T n (h) 2

5 2.3 Transmsson Lnes The transmsson lnes data s gven n Table 5. The lnes are characterzed by the nodes that are connected, as well as the reactance and the capacty of each lne. The data s based on [2]. Table 5: Reactance and Capacty of Transmsson Lnes From To Reactance Capacty Reactance Capacty From To (p.u.) (MVA) (p.u.) (MVA) Implementaton Includng Wnd Power Producton It s recommended to nclude sx wnd farms of 200 MW capacty at dfferent locatons throughout the grd. It s proposed to locate the wnd farms at 3, 5, 7, 16, 21 and 23 nodes. In ths case, as proposed n [7], the capacty on the transmsson lnes connectng the node pars (15,21), (14,16) and (13,23) s reduced to 400 MW, 250 MW and 250 MW, respectvely. Ths s done n order to ntroduce bottlenecks n the transmsson system. Moreover, a set of avalable wnd power scenaros s provded at [6]. The 24-bus power system or a modfed verson s used n varous publcatons, such as at [4], [7] and [8]. References [1] C.
