In test system-II, primarily a two area multi source power system is considered with three GENCOs and two DISCOs in each area is shown in Fig. 8. The control area 1 and control area 2 comprises of reheat thermal, hydro and gas power system with the inclusion of non-linearities such as boiler dynamics, time delay (TD), governor dead band (GDB) and generation rate constraint (GRC). Boiler dynamics configuration is incorporated in thermal plants to generate steam under pressure. Changes in the steam flow and deviations in pressure are sensed, and the corresponding action is initiated by the turbine control valves and boiler control the steam flow and deviations in pressure are sensed, and the corresponding action is initiated by the turbine control

It is assumed that the two DISCOs in control area-1 demands 5% p.u.MW of power from the GENCOs of the same control area and the DISCOs in control area-2 have not any contract with the GENCOs in area-2. Hence, the load disturbance in area-1 is 10% p.u.MW and the load disturbance in area-2 is zero. A particular case of Poolco based contracts between DISCOs and available GENCOs is simulated based on the following …show more content…
As STPP included in the area-1, contracts between DISCOs and available GENCOs can be modified as given in the following DPM but a care has taken while choosing the contracts between DISCOs and GENCOs such that the there is no deviation in tie-line power. Further, the TCPS is incorporated in the tie-line to analysis its effect on the power system performance. Then SMES units are installed in both the areas to study the effectiveness of TCPS-SMES coordinated system on system performance. The final optimized gain values with proposed technique under this transaction are shown in Table 5 and the corresponding performance index values are given in Table 6. It is clear from Table 6 that the objective function ISE value is minimized to 1.8098 by integrating STPP and it is reduced to 1.6137 when TCPS is coordinated in the system. The objective function value further reduces to 0.6660 when the system coordinated with both TCPS and SMES. It can be seen from Table 6 that with TCPS and SMES, the settling times, peak and under shoots of change in area frequencies and change in tie-line power are improved greatly compared to others. The dynamic performances of the system are shown in Fig. 11 (a)-(c). It is clear from Fig. 11 (a)-(c) that better dynamic performance is obtained with TCPS and SMES coordinated system
