Summary This paper aims to propose the small‐signal model of a wind turbine (WT) based on a doubly fed induction generator (DFIG) and a solid oxide fuel cell (SOFC) into the transmission network for dynamic stability analysis of the integrated system. The principal goal is to introduce the novel small‐signal model of the hybrid power system in the presence of the WT and SOFC power plants for analyzing of electromechanical oscillations. Therefore, the modeling of each generation unit of the integrated system in the same framework is illustrated. Besides, a comprehensive mathematical model is demonstrated from WT and SOFC units integrated with a synchronous generator (SG) and the infinite bus system. Based on the proposed model, the linear analysis is illustrated under different conditions for stability studies. Moreover, this study presents the influence of different portions of WT and SOFC units on the small‐signal stability. The simulation results represent the performance of the suggested model.

“…As two typical types of renewable energy, wind power and PV are extensively installed in distributed power systems because of their environmental friendliness and easy maintenance characteristics. However, both of their outputs can be greatly influenced by the weather, which may cause network power fluctuation and bring harm to the safety operation of the power grid [22][23][24]. Therefore, in distributed power systems, a fossil energy generation system is usually equipped to alleviate renewable energy system output power fluctuation.…”

Abstract:With the rapid development of industry, more fossil energy is consumed to generate electricity, which increases carbon emissions and aggravates the burden of environmental protection. To reduce carbon emissions, traditional centralized power generation networks are transforming into distributed renewable generation systems. However, the deployment of distributed generation systems can affect power system economy and stability. In this paper, under different time scales, system economy, stability, carbon emissions, and renewable energy fluctuation are comprehensively considered to optimize battery and super-capacitor installation capacity for an off-grid power system. After that, based on the genetic algorithm, this paper shows the optimal system operation strategy under the condition of the theoretical best energy storage capacity. Finally, the theoretical best capacity is tested under different renewable energy volatility rates. The simulation results show that by properly sizing the storage system's capacity, although the average daily costs of the system can increase by 10%, the system's carbon emissions also reduce by 42%. Additionally, the system peak valley gap reduces by 23.3%, and the renewable energy output's fluctuation range and system loss of load probability are successfully limited in an allowable range. Lastly, it has less influence on the theoretical best energy storage capacity if the renewable energy volatility rate can be limited to within 10%.

“…Recent publications exist exploring the effect of increasing grid RES levels on its rotational inertia and stability following a disturbance. This has usually been achieved by finding relevant physical characteristics using simulations on various testbeds, e.g., [1]- [4] simulated the dynamic response, [2] analysed the eigenvalue sensitivity, [5] investigated the effects on the rate of change of rotor speed, and [3], (using a fivemachine reduced model to represent The Western Electric Coordinating council transmission grid) investigated inter-area power-flow oscillations. Additionally, methods have been proposed for tuning system parameters to account for high RES penetration.…”

The absolute requirement to increase the amount of energy generation from renewable sources e.g. predominantly asynchronously connected wind turbines and photovoltaic installations, may in practice during transient events (where frequency changes are examined) excite oscillatory response of the power output of large grid connected synchronous-generators. The response of such generators must be controlled either by varying the applied torque of a turbine or by altering the electromagnetic torque in the airgap. Choosing the latter, the adequacy of a voltage regulator, particularly that of the embedded Power System Stabilizer (PSS) circuit, is investigated using the IEEE PSS1A model for the automatic voltage regulator of a synchronous generator driven by a gas turbine. The response is obtained via closed form analytic solutions for both small (linear) and large (nonlinear) scale transient events in the energy grid system. In tandem with the analytical study, the behavior simulated with a computer model from MatLab-SimPowerSystems is reviewed.
