Summary In the modern world, only conventional energy resources cannot fulfil the growing energy demand. Electricity is a fundamental building block of a technological revolution. Today, most of the electricity demand is met by the burning of fossil fuels but at the cost of adverse environmental impact. In order to bridge the gap between electricity demand and supply, nonconventional and eco‐friendly means of energy generation are considered. Renewable energy systems (RESs) offer an adequate solution to mitigate the challenges originated due to greenhouse gasses (GHG). However, they have an unpredictable power generation with specific site requirements. Grid integration of RESs may lead to new challenges related to power quality, reliability, power system stability, harmonics, subsynchronous oscillations (SSOs), power quality, and reactive power compensation. The integration with energy storage systems (ESSs) can reduce these complexities that arise due to the intermittent nature of RESs. In this paper, a comprehensive review of renewable energy sources has been presented. Application of ESSs in RESs and their development phase has been discussed. Role of ESSs in increasing lifetime, efficiency, and energy density of power system having RESs has been reviewed. Moreover, different techniques to solve the critical issues like low efficiency, harmonics, and inertia reduction in photovoltaic (PV) systems have been presented. Unlike most of the available review papers, this article also investigates the impact of FACTS technology in RESs‐based power system using multitype flexible AC transmission system (FACTS) controllers. Three simulation models have been developed in MATLAB/Simulink. The results show that FACTS devices help to maintain the stability of RESs integrated power system. This review paper is believed to be of potential benefit for researchers from both the industry and academia to develop better understanding of challenges and solution techniques for REs‐based power systems and future research dimensions in this area.

“…Therefore, it is meaningful to study and explore the dynamics of a compensated system. The unique features of SSR effects are induction generator effect (IGE), torque amplification (TA), and torsional interactions (TI) . TA is due to sudden large disturbances in the system and it is categorized under transient SSR.…”

Summary The interconnection between the grid and nonconventional energy sources has become more essential due to the huge rise in energy demand. In the case of wind energy, the grid integration undergoes lots of stability issues. The long‐distance transmission lines are preferred since the wind farms are positioned far from the grid. However, this lowers the bulk power transfer ability of the line. The simple solution to enhance the power transfer capacity is the insertion of series capacitor in the line. However, the frightening factor in inserting the series capacitor is subsynchronous resonance (SSR) oscillations which can lead to shaft fatigue between turbine and generator set. This paper focuses on the analysis of SSR in series‐compensated doubly fed induction generator (DFIG)–based wind energy conversion systems (WECSs). The detailed mathematical modelling of DFIG‐based wind turbine generator (WTG) in state space form which is essential for SSR analysis is explained. The proposed model is found to be more accurate as it includes the dynamics of the rotor‐side converter (RSC) and grid‐side converter (GSC). The influence of series capacitive compensation in a WECs is dealt by employing eigenvalue approach. The developed model is embedded with RSC and GSC controllers for analyzing SSR effect for different operating conditions such as wind speed variations and varying compensation levels using MATLAB/SIMULINK. Also, the scaled‐down model of a 2‐MW wind turbine is deployed in laboratory using a grid‐integrated, series‐compensated 1.1‐kW DFIG machine to realize the influence of series capacitive compensation. It is found that the stability of SSR is affected by different wind velocities and capacitive compensation levels.

Abstract:The successful application of the unified power flow controller (UPFC) provides a new control method for the secure and economic operation of power system. In order to make the full use of UPFC and improve the economic efficiency and static security of a power system, a preventive security-constrained power flow optimization method considering UPFC control modes is proposed in this paper. Firstly, an iterative method considering UPFC control modes is deduced for power flow calculation. Taking into account the influence of different UPFC control modes on the distribution of power flow after N-1 contingency, the optimization model is then constructed by setting a minimal system operation cost and a maximum static security margin as the objective. Based on this model, the particle swarm optimization (PSO) algorithm is utilized to optimize power system operating parameters and UPFC control modes simultaneously. Finally, a standard IEEE 30-bus system is utilized to demonstrate that the proposed method fully exploits the potential of static control of UPFC and significantly increases the economic efficiency and static security of the power system.
