“…Here a performance index calculation for PJM 5-bus test system is performed to see how security considerations affect the utilization performance for branches of the system. according to [24] the smaller the PI MW in one scenario the better the performance of system branches utilization and the lower the risk of the system operation in a scenario. shows that when ESS units being discharged at hours 11, 14, 23 and 24 the line flows get slightly higher.…”

This study is focused on assessing the effect of energy storage system (ESS) presence on security improvement of power systems hosting remarkable renewable energy resources. To this end, ESS presence is suitably included in security-constrained optimal power flow (SCOPF) model; the required technical amendments are hence considered. To launch a realistic model, ramping constraints of thermal units are also taken into account, which, limit the generators from completely responding to power shortfalls. Considering a high penetration level of renewable generations, different scenarios of outages in transmission lines and generators are simulated to measure the line outage distribution factor (LODF) and power transfer distribution factor (PTDF). Also, in order to illustrate the economic impact of wind power generation curtailment and load shedding, two penalty parameters value of wind curtailment (VWC) and value of loss of load (VOLL) are considered in the model. Two test systems, including a PJM 5-bus system and an IEEE 24-bus RTS, are put under numerical studies to assess the possible impact of ESS on security improvement of the investigated systems. The obtained results are discussed in depth.

“…Literature shows the various needs of the index, some of them are listed as follows: To improve the ability of the system to withstand particular equipment outages without loss of service [8]. To improve secured power dispatch and control. To ensure corrective rescheduling. To make preventive control actions [10].…”

“…Day‐ahead and hours‐ahead generation schedules are achieved by the decomposition algorithm which significantly reduces the computation time to meet the requirements of assessment. To monitor exponential divergent power flow, apart from the usual MW performance index for dynamic SA, a discrete Largest Lyapunov Exponent as a supportive chaotic index is discussed in [8]. Ranking the overall performance index for line outage based on the active power, and the voltage performance index using Newton Raphson load flow method is mentioned in [9].…”

Several power system networks exhibit bifurcation, chaos and instability behavior for some specific values of initial conditions and parameters. Angle and voltage instability behavior of power system is prone to such specific values and parameter variation. This paper proposes fractional order proportional integral controller (FOPI) based state feedback for precise and robust control of such undesirable behavior. This paper proposes first ever use of FOPI for precise rotor angle control leading to instability in power system dynamic behavior. FOPI controller is applied on generator connected to IEEE-14 bus benchmark model. The ripple frequency of turbine torque is chosen as one of the cause of instability behavior of power system, which has the potential possibility to push system behavior to chaos and instability mode. The proposed FOPI controller design will inhibit the dynamic behavior of power system to safe and stable bounds. Proposed strategy can be applied to other large power system models as well due to its simplicity in design philosophy. Several phase plane trajectories with and without FOPI controller are used to support the viewpoint.
