“…Generally, each REPP consists of three essential components including energy converter such as PV arrays or turbine generators, inverters, and controllers. The HREPPs also have these three components, but they use two or more types of REGUs [5]. In these power plants, each REGU has its own special controller.…”

“…These models had their own problems although they could satisfy the study requirements in many cases. However, the lack of a generic, accessible, and flexible model, which could be used for a variety of REPPs, was evident before expanding the establishment and development of REPPs [5]. Although different models have been presented by well-known companies and institutes later [14][15][16][17], the model introduced by Western Electricity Coordinating Council (WECC), called first-generation generic model, is regarded as the leading one [19].…”

“…Due to the increasing tendency to use the HREPPs, WECC and Electric Power Research Institute (EPRI) conducted some studies to present a generic model for this type of power plants. Ultimately, an initial model called GHCM was presented by them in 2016 [5,21]. This model, which is based on the SGGM, is currently under development [5].…”

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.

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.

Computer models designed to assess harmonic levels created by renewable energy sources (RESs) need to reproduce the converter operation effect. However, only a few simplified time‐domain models have been developed to predict harmonics while reducing simulation time, which is one of the main limitations of detailed models. This paper presents a novel time‐domain model, called the harmonic average model (HM), to estimate harmonic currents generated by inverters. The superposition principle is applied to include dead time and switching effects in the average model. In addition, the snubber effect is considered by introducing snubber circuits in the HM. Time‐domain simulations of a type‐IV wind turbine are executed with existing models and then with the HM to evaluate the proposed model. Field measurements in a wind power plant and in a photovoltaic plant are used to validate the HM under different power injection scenarios. The results indicate that the HM follows reference currents while accurately estimating the harmonic spectra. Further, the HM is relatively simple to deploy and reduces computation time. A comparison between the HM results and field measurements suggests that the simulated spectra are an adequate approximation of the measured spectra. These results confirm that the HM can be used by transmission system operators to support the prediction of harmonic currents generated by inverters and to estimate the impact of RESs on voltage quality.
