“…which is based on pole placement 8,9 ; and the other one is related to wide-area measurement system (WAMS). 10,11 In the small-signal stability analysis, due to linearization around the operating point, the nonlinear factors are not considered. However, the validity limitation of the model and parameter of the WAMS is not under consideration, and this can be regarded as an advantage.…”

“…In this scenario, a permanent three-phase fault occurs near bus 4 (in line [4][5][6][7][8][9][10][11][12][13][14] at the time of 2 seconds, and as the fault is not cleared after 0.1 seconds, the line 4-14 is gotten out of the circuit. The wind speed and solar irradiation patterns are considered similar to the first scenario.…”

Summary The main purpose of this article is to design a wide‐area damping controller (WADC) considering time delay compensator (TDC) in large‐scale power systems in the presence of renewable energy sources. The TDC is designed to create an opportunity for compensation of uncertainty caused by the phase delay. Then, considering the retrieved uncertainty, H∞/H2 synthesis method is used to make robust the WADC so that the controller can compensate long and continuous delays. This design is done for two hybrid renewable energy systems (HRESs) connected to a 16‐machine, 68‐bus power system. The first HRES includes photovoltaic and permanent magnet synchronous generator (PMSG) fields in which a super‐capacitor‐based energy storage system is used in the DC link in order to improve the oscillations of the injected power resulted from the variations of wind speed and solar irradiation. The second HRES includes offshore wind farm and shore wind farm with double‐fed induction generator units, and also, offshore tidal farm with PMSG units. This HRES delivers its generated power to the system through a high voltage direct current (HVDC) line. The design of the damping controller is implemented based on WADC and local control on HVDC and super capacitor converter. The simulations have been carried out in different scenarios in the MATLAB environment to demonstrate the robustness of the proposed approach.

“…In this section, an objective function based on eigenvalue is used to optimize parameters of damping controller . In this objective function, the real parts and the damping ratio of nondamping modes are formulated as follows:

Summary The present article aims to improve the small signal stability in a large‐scale network using model predictive control (MPC). The predictive strategy is based on the Laguerre function so as to reduce computational time in MPC and increase precise detection of control signals. This strategy is implemented in such a way to control the active and reactive power on rotor‐side converter (RSC) and increase RSC yield in the presence of uncertainties through application of appropriate switching to inverter. Therefore, static synchronous compensator is used in a way that the reactive power is compensated and by designing a damping controller the interarea oscillations will be reduced in New England large‐scale system. The simulation results were evaluated using MATLAB software in the field of time and frequency under different scenarios. Moreover, the proposed method was compared with conventional MPC and proportional‐integral controller while its superiority to stabilize and reduce the computational time is clearly shown.

Summary The contribution of hybrid controller of large‐scale wind power generation system (LWPGS) in system stability and profit is discussed throughout the paper. To this purpose, it is necessary to formulate the impact of high infiltration of wind turbines on the dynamic stability of power networks. A mathematical model of a multi‐machine power network is developed first, based on which an extended small‐signal stability analysis procedure is projected and discussed to handle the influence of LWPGS on oscillatory modes. This model is then applied for analyzing the damping impact of the LWPGS and ancillary service (AS) associated with its controller. After the model creation, the profit created by LWPGS hybrid controller as AS is analyzed by multi‐objective optimization based on low‐frequency oscillation stability criterion and generation cost. Two scenarios for the valuation of small‐signal stability as an AS provided by LWPGS controller are considered. The study is based on a changed 16‐machine 5‐area network. The comparative analysis of the results is also presented to elucidate the suggested approach. Copyright © 2015 John Wiley & Sons, Ltd.
