INTERCONNECTION FACILITIES STUDY AGREEMENT,ATTACHMENT C LODI ENERGY CENTER 7.3 System Protection Analysis Preliminary system protection requirements will be provided based on the scope and assumptions outlined in this study plan and technical information provided by the IC. 7.4 Reactive Power Deficiency Analysis With the proposed project included in the system model, CAISO Category"B"and "C contingencies will be analyzed to identify any reactive power deficiency: • Whether the results show voltage drops of 5% or more from the pre-project levels, or • Whether the results fail to meet applicable voltage criteria. A post-transient power flow analysis will be performed, if deemed necessary, after considering the network topology or power transfer paths involved when a significant amount of power transfer occurs. 7.5 Dynamic Stability Analysis Dynamic stability studies will be conducted using the 2012 Summer Peak Full Loop Base Case to ensure that the transmission system remains in operating equilibrium through abnormal operating conditions after the new facility begins operation. Disturbance simulations will be performed for a study period of up to 20 seconds to determine whether the new facility will create any system instability during the following line and generator outages: 7.5.1 CAISO Category"B" • Full load rejection of 280 MW of the Project. • Three phase fault with normal clearing time at Eight Mile Road 230 kV bus, Section E,followed by the loss of the Lodi Stig— Eight Mile Road 230 kV line. • Three phase fault with normal clearing time at Gold Hill 230 kV Bus#1, followed by the loss of the Gold Hill—Lodi Stig 230 kV line. 7.5.2 CAISO Category"C" • Three phase fault at Eight Mile Road Substation 230 kV bus, Section E, with normal clearing time 8
