“…These results of stability studies recommended the possibility of accommodation of maximum wind generation of 29.3% without loss of stability from previous 26.8% by comparing stability cases of operating scenario studied and increased operating scenario are given in Table 2. Further, the authors calculated the reserve margin requirement for the TANGEDCO system for the operating scenario of 26.81% wind penetration to be between 553 MW and 605 MW and the increased operating scenario of 29.29% wind penetration to be between 579 MW and 749 MW, and they advised that a reserve margin of approximately 4.7% be maintained to achieve 30% wind penetration [18], [19]. This study thoroughly examined the stability of the current system in the event of a sudden cessation of wind generation and made recommendations for the necessary variables to enhance wind penetration levels in the TANGEDCO system for stable operation of the power system network.…”

Due to its inherent geographical potential for wind/solar power and other renewable energy sources (RES) generation, Tamil Nadu is one of the pioneering Indian states in the early development and utilisation of RES. Tamil Nadu accounts for roughly 25% of India's total wind energy capacity. Increased penetration of RES in a power system indicates that RESs have replaced traditional power plants that have historically managed and stabilised the power system, resulting in novel power flow situations. Grid stability must be enhanced in light of the integration of large-scale RES into the grid. The purpose of this research is to analyse and evaluate the impact of large-scale integration of RES by examining mitigating methods from the most recent academic articles and technical reports in this field. This will aid in identifying the key risks affecting the network's stability margin as a result of the widespread integration of RES generation, allowing for a reasonable increase in the network's stability margin. The study's findings will also help to guide the selection of appropriate mitigation strategies. As the stability margin improves, the future fraction of RES additions to the Tamil Nadu extra high voltage (EHV) grid will be increased significantly.

“…However, Variable speed wind turbines such are DFIG & PMSG have no reactive power constraints. Thus, these wind turbine generators have fault ride through capability with power electronics converter control [26]. Figure 8 shows the fault ride through characteristics of wind turbine generators connected to the grid.…”

Among all the Renewable Energy Sources Wind energy is the fastest growing energy source over the last decade mainly due to crucial developments of technology in wind energy. Nowadays, the penetration of wind energy is increasing in many countries in the world including India. The power system stability with large penetration of wind power is a concern for many electrical utilities. The common technical issues with increased penetration of wind energy are voltage and reactive power control, frequency control and Low Voltage Ride Through (LVRT) capability. The VSC-HVDC system with its benefit of independent control of active and reactive power promises to enhance the system stability at high penetration levels. The maximum wind penetration levels in to the grid is analysed for Fixed Speed Induction Generator (FSIG) & Doubly Fed Induction Generator (DFIG). The penetration levels are further enhanced by considering the evacuation of wind power with VSC-HVDC system without losing system stability. Different controllers for VSC-HVDC system are used to improve the stability and LVRT capability. Standard Benchmark System is considered, and the simulations are performed by using power system simulation software SIMPOW. Results shows that wind power evacuated through VSC-HVDC system has better stability and LVRT Capability compared to AC system at high wind penetration levels.

“…[9]. WPP and SPP negatively affect the power quality: they can generate higher harmonic components, and create fast voltage fluctuations in the electric power system [8,10]. It is necessary to take into account the economic costs of technical measures related to the mitigation of these negative impacts of the WPP and SPP, providing a reserve of generating capacities [3].…”

The paper discusses the problem of parallel operation of wind and solar power plants with the power system associated with the influence of power fluctuations on the power quality and stability. A brief assessment of the prospects for the commissioning of the wind and solar power plants in Russia and a description of the associated negative impacts on the power system is given. A methodology for assessing the possible energy production of wind and solar power plants using raw data from weather stations is presented. Based on the methodology, an assessment of some regions of Russia in relation to the variability of wind speed and cloudiness is made. The wind power duration curves are given. An analysis of possible deviations of solar power under the influence of cloudiness is carried out. The effect of geographical aggregation of wind or solar power output to increase the guaranteed power generation and reduce the negative impact on the stability of the energy system is shown.
