“…In the following section, a model for the prime mover is derived from basic heat transfer and thermodynamics principles. This is unlike [8] where the authors have utilized a simple first-order transfer function to model the DS system, and without clear justification on how the model can be sufficiently accurate for the purpose of designing the control system for the DS system.…”

“…As the purpose of the present investigation is to design temperature and speed control systems for the DS-DFIG, the model used in [8] for the induction machine and converter can be simplified by ignoring the much faster electromagnetic dynamics. Traditionally, current control forms the inner loop of the doubleloop feedback PI control of DFIG whereas the outer loop is for speed/power control.…”

“…Appropriate system design and operations of the DS power plant are called for. In this connection, the development of suitable DS model for the power plant and control system has been reported in [2]- [8]. In the authors' previous work [2], the steady-state relationship between the engine speed and the generated power has been derived.…”

“…Review no suitable mathematical model has been derived. Existing models of the prime mover proved to be either too complex [5]- [7] or so simplified that they are unsuitable for use in power system studies [8]. Furthermore, in adopting variable-speed operations for the DS system, doubly fed induction generator (DFIG) is attractive due to its economic advantage over permanent magnet synchronous generator (PMSG).…”

“…[9], the present investigation shall show that the design of control scheme for such a DS-DFIG system is more complex because the power regulating ability of the generating system will be impacted by the receiver operating temperature. The approach described in [8] ignores the temperature effects and as a result, it can lead to unrealistic prediction of the steady-state and dynamic performances of the DS system. Accordingly, Section II introduces the overall system configuration of the proposed DS-DFIG power plant.…”

Analysis on a developed dynamic model of the dishStirling (DS) system shows that maximum solar energy harness can be realized through controlling the Stirling engine speed. Toward this end, a control scheme is proposed for the doubly fed induction generator coupled to the DS system, as a means to achieve maximum power point tracking as the solar insolation level varies. Furthermore, the adopted fuzzy supervisory control technique is shown to be effective in controlling the temperature of the receiver in the DS system as the speed changes. Simulation results and experimental measurements validate the maximum energy harness ability of the proposed variable-speed DS solar-thermal system.

This paper aims to investigate a hybrid cycle consisting of a molten carbonate fuel cell (FC) and a Stirling engine which, by connecting to a seawater reverse osmosis desalination unit, provides fresh water. First, a parametric evaluation is performed to study the effect of some key parameters, including the current density and the working temperature of the FC and the thermal conductance between the working substance and the heat reservoirs in the Stirling engine, on the objective functions. The objective functions include the energy efficiency, the exergy destruction rate density, the fresh water production rate, and the ecological function density. After investigating each double combination of these objective functions, two scenarios are defined in quest to concurrently optimize three functions together. The first scenario aims to optimize the energy efficiency, the exergy destruction rate density, and the fresh water production rate; and the second scenario attempts to optimize the energy efficiency, the fresh water production rate, and the ecological function density. A multi‐objective evolutionary algorithm joined with the nondominated sorting genetic algorithm (NSGA‐II) approach is employed to obtain Pareto fronts in each case scenario. In order to ascertain final solutions between Pareto fronts, three fast and robust decision‐making methods are employed including TOPSIS, LINMAP, and Fuzzy. Finally, a sensitivity analysis is conducted to critically analyze the performance of the system.

The effective and reliable operation of an interconnected power system (PS) is a major concern, because of the large amount of power contribution from the intermittent renewable energy sources to the power grid. Energy storage (ES) devices are employed to enhance the reliability of the PS operation. Electric vehicles (EVs) are a novel type of distributed ES device that may be utilized to compensate for power imbalances. This paper discusses the participation of EVs for combined frequency and voltage control under conventional PS along with a thermal, hydro, realistic dish‐Stirling solar thermal system (RDSTS). Appropriate physical constraints such as governor dead band and generation rate constraints are equipped with thermal and hydro plants, and communication delay between the generating unit and load dispatch center is considered. An aggregate EVs model, RDSTS, and a new cascade controller named fractional‐order proportional‐derivative with filter coefficient cascaded with tilt‐integral‐derivative (CFOPDN‐TID) controller are provided in all areas for various studies. An artificial flora algorithm is employed to determine the optimal value of the various controller parameters under several scenarios. The system dynamics of the CFOPDN‐TID controller outperform the proportional‐integral‐derivative (PID) and TID controllers under various conditions. The incorporation of EVs improves the system performance in terms of less settling time, and peak deviation, and reduce oscillations. The system performance degrades with increases in the communication time delay of the EVs. The integration of RDSTS into the system provides better dynamics than the dish‐Stirling solar thermal system. Numerous studies have been conducted to validate the robustness of the proposed CFOPDN‐TID controller.
