“…Chiandone et al [8] estimated power losses on an actual low voltage distribution network according to the distributed generation penetration and placement of the power units by using a Python-based software tool for power system analysis. Imen et al [9] analysed the influence of wind farm integration on load flow and voltage in electrical power system. An assessment framework to address the power quality issues that have arisen after integrating large-scale wind farms into weak transmission grids, especially considering inter-farm wake effect, seasonal variations, reactive power depletion, and compensation with a variety of voltage-ampere reactive devices by using MATLAB/Simulink was presented in [10].…”

<p>The rapid integration of wind power and power solar plants into the electrical power system has caused several operation issues in recent decades. To investigate the impact of large-scale renewable power plants on the tie-line loadings of a practical power grid, the 110 kV power network of Binh Dinh province, Vietnam is utilized in this paper. This power network with and without three solar power plants (including Fujiwara plant with a peak capacity of 50 MWp, Cat Hiep plant with a peak capacity of <br />49.5 MWp, and Dam Tra O plant with a peak capacity of 50 MWp) and three wind power plants (including Nhon Hoi plant with a capacity of 60MW, Phuong Mai 1 plant with a capacity of 26.4 MW, and Phuong Mai <br />3 plant with a capacity of 20.7 MW) is modeled by using the PSS/E software to examine the tie-line loadings capacity. The simulation results showed that the tie-line loadings of the current power network increase when six renewable power plants are integrated into this network. Therefore, three different scenarios to upgrade the existing power network are proposed. The final results demonstrated the efficiency of the proposed scenarios in solving the tie-line loadings issue of the practical power network.</p>

“…To maintain voltage levels under acceptable ranges, severe wind speed changes were resolved in [22], utilizing active (P) and reactive (Q) power-coordinated controllers established on multi-scale model predictive control theory. Wake effect and wind intermittency amplify PQ concerns in LSWF, resulting in variable output power that affects voltage stability [23,24], frequency stability [24], harmonics [23], fault ride-through [25], and power factor [26]. The incorporation of the LSWF into transmission grids raises the risk of Q compensation issues, which have been studied in a variety of situations for a variety of applications, most notably in FACTS.…”

“…UPFC can manage both active and reactive power flows, increasing the system's stability rapidly and constantly [30]. Furthermore, in different evaluation scenarios, the static synchronous series compensator (SSSC), UPFC, and STATCOM all result in enhanced Q compensations and have a positive impact on voltage profiles and load flows [25,31].…”

Techno-Economic and Environmental Impact Analysis of Large-Scale Wind Farms Integration in Weak Transmission Grid from Mid-Career Repowering Perspective

Repowering a wind farm enhances its ability to generate electricity, allowing it to better utilize areas with high mean wind speeds. Pakistan’s present energy dilemma is a serious impediment to its economic development. The usage of a diesel generator as a dependable backup power source raises the cost of energy per kWh and increases environmental emissions. To minimize environmental emissions, grid-connected wind farms enhance the percentage of wind energy in the electricity system. These wind generators’ effects, on the other hand, are augmented by the absorption of greater quantities of reactive electricity from the grid. According to respective grid codes, integration of commercial onshore Large-Scale Wind Farms (LSWF) into a national grid is fraught with technical problems and inter-farm wake effects, which primarily ensure power quality while degrading overall system operation and limiting the optimal use of attainable wind resources. The goal of this study is to examine and estimate the techno-economic influence of large-scale wind farms linked to poor transmission systems in Pakistan, contemplating the inter-farm wake effect and reactive power diminution and compensating using a range of voltage-ampere reactive (VAR) devices. This study presents a partial repowering technique to address active power deficits produced by the wake effect by raising hub height by 20 m, which contributed to recovering the active power deficit to 48% and so reduced the effects of upstream wind farms. Simulations were conducted for several scenarios on an actual test system modeled in MATLAB for comparative study using capacitor banks and different flexible alternating current transmission system (FACTS) devices. Using the SAM (System Advisor Model) and RETscreen, a complete technical, economic, and environmental study was done based on energy fed into the grid, payback time, net present value (NPV), and greenhouse gases (GHG) emission reduction. The studies suggest that the unified power flow controller (UPFC) is the optimum compensating device via comparison analysis as it improved the power handling capabilities of the power system. Our best-case scenario includes UPFC with hub height augmentation, demonstrating that it is technically, fiscally, and environmentally viable. Over the course of its lifespan, the planned system has the potential to save 1,011,957 tCO2, resulting in a greener environment. When the energy generated annually by a current wake-affected system is compared to our best-recommended scenario, a recovered shortfall of 4.851% is seen, with improved system stability. This modest investment in repowering boosts energy production due to wake effects, resulting in increased NPV, revenue, and fewer CO2 footprints.

Integrating wind power and solar power plants into a power system has significantly grown over the past decade and is expected to grow to unprecedented levels in the coming years. In Vietnam, much large-scale wind power and solar power plants have been built and connected to the power system in recent years. To investigate and evaluate the impact of these power plants on system power operation, the 110kV power transmission network of Binh Dinh province in Vietnam is used in this paper. In the system, the Phuong Mai 3 wind power plant with a capacity of 21MW, the Fujiwara solar power plant with a peak capacity of 50MWp, and the Cat Hiep solar power plant with a peak capacity of 49.5MWp are modeled by using the PSS/E software to simulate and analyze their impacts on power system stability of the 110kV transmission network in Binh Dinh province, Vietnam. Besides, the control strategies of these power plants are also established to investigate their impacts on the network. In addition, this paper proposes three typical scenarios for the wind power and solar power plants in the system. For each scenario, the grid's operating parameters such as voltage variations and frequency variations are acquired for analyzing and evaluating their impacts on the frequency and voltage variations of the network. The simulation results show that the 110kV power transmission network remains in a stable operation mode after the fault scenarios for the wind and solar power plants. Furthermore, these simulation results provide some guidance for the actual operation
