“…Further, the P/f control strategy is selected as the f control. Also, the variation of generators speed across the two areas is defined as the input signal of the WMFOPID controller 28,30 . Based on the LPF position in the power system, the signal transmission delay among PMU, PDC, and WMFOPID controller should be defined as a constant time delay, T m .…”

Summary In recent years, the installation of large‐scale photovoltaic (PV) farms (LPFs) is expanding around the world. Due to the addition of LPFs to the power system and increasing their penetration level, they should be able to undertake the most common tasks of conventional power plants in coordinated with other devices in the power system. Damping of low‐frequency oscillation (LFO) through the power system stabilizers (PSSs) is regarded as one of these common tasks. Therefore, the LPF must be able to damp the LFO in coordinated with the PSSs. This paper proposes a new method for LFO damping in power system which is based on optimal coordination of wide‐area measurement‐based fractional‐order proportional‐integral‐derivative (WMFOPID) controller as an auxiliary controller for LPF and PSSs of synchronous generators. The performance evaluation of the optimal coordinated WMFOPID controller is performed in a smart two‐area power system and is compared with other controllers in terms of LFO damping. The simulation results show the better performance of the optimal coordinated WMFOPID controller compared to the uncoordinated case and determine the effectiveness of the novel proposed method for LFO damping. The results also show the high robustness of the optimal WMFOPID controller compared to previous controllers, against some uncertainties in the power system.

Summary The penetration of large‐scale photovoltaic farms (LPFs) is ever increasing. Given that LPFs are added to power systems or replaced by conventional power plants, they should undertake the most common tasks of synchronous generators. One of these tasks is the low‐frequency oscillation (LFO) damping using power system stabilizer. This paper proposes a general method for LFO damping using LPFs by designing an optimal proportional‐integral‐derivative (PID) controller as a power oscillation damper in the nonlinear control loop of LPF. Considering the need for a valid LPF model, therefore the second generation generic model, developed and approved by western electricity coordinating council, is used. The PID controller is optimally tuned using the particle swarm optimization algorithm in order to produce an effective LFO damping. Finally, the performance of this controller is investigated in the modified two‐area test system, showing the proper performance of the LPF for LFO damping using the proposed optimal PID controller in the various operating condition and different short circuit ratio values.

“…Thus, this method cannot be implemented here. In the present study, the frequency difference of two areas is considered to be the OPOD input signal [26,29]. In the next step, the K OPOD ,T 1 , T 2 ,T 3 , and T 4 are determined.…”

Global warming, increase in environmental pollution, and high cost of electrical power generation using fossil fuels are considered the most important reasons for the application of renewable energy power plants (REPPs) around the world. In recent years, a new generation of REPPs called hybrid renewable energy power plants (HREPPs) has been implemented in order to have higher efficiency and reliability than conventional REPPs such as wind power plants and photovoltaic power plants. The HREPPs include two or more renewable energy generation units such as wind turbine generation units, and PV generation units. In case of high penetration of these types of power plants, the most common tasks of synchronous generators should be supported by them. One of these tasks is the ability to reduce the low-frequency oscillation (LFO) risk through power oscillation damper such as the power system stabilizers of synchronous generators. In this paper, a novel method is proposed for LFO damping by HREPPs, which is based on the design of an optimal power oscillation damper (OPOD) implemented in the generic HREPP controller model. The structure of the proposed OPOD is a 2nd-order single-input lead-lag controller, and its performance is investigated in a modified two-area test system. The simulation results show the proper performance of the HREPP for LFO damping using the proposed OPOD in the various loading levels and different short circuit ratio values.
