“…Furthermore, the injected current control is achieved through three Proportional Resonant (PR) controllers upon the abc three-phase frame. More design details with respect to the control designs of GcCs can be found in the previous literatures [37][38][39]. Regarding the unbalanced conditions, various control strategies have been proposed before [40,41].…”

An extended state observer (ESO)-based loop filter is designed for the phase-locked loop (PLL) involved in a disturbed grid-connected converter (GcC). This ESO-based design enhances the performances and robustness of the PLL, and, therefore, improves control performances of the disturbed GcCs. Besides, the ESO-based LF can be applied to PLLs with extra filters for abnormal grid conditions. The unbalanced grid is particularly taken into account for the performance analysis. A tuning approach based on the well-designed PI controller is discussed, which results in a fair comparison with conventional PI-type PLLs. The frequency domain properties are quantitatively analysed with respect to the control stability and the noises rejection. The frequency domain analysis and simulation results suggest that the performances of the generated ESO-based controllers are comparable to those of the PI control at low frequency, while have better ability to attenuate high-frequency measurement noises. The phase margin decreases slightly, but remains acceptable. Finally, experimental tests are conducted with a hybrid power hardware-in-the-loop benchmark, in which balanced/unbalanced cases are both explored. The obtained results prove the effectiveness of ESO-based PLLs when applied to the disturbed GcC.

“…The general procedure of obtaining the reduced-scale hydraulic model is schematically described in Figure 1, which will be detailed in the following parts. This method differs from the scenario discussed in [34], as an actual full-scale 'Hill Charts' data of a bulb turbine is used in computing the mathematical model, without the need of removing the unstable region (S-region) [35]. In addition, being different from the modelling approach proposed in [28], the models of water flow rate and efficiency are regressed through solving optimization problems.…”

Variable Speed Hydro-Electric Plant (VS-HEP) equipped with power electronics has been increasingly introduced into the hydraulic context. This paper is targeting a VS-HEP Power Hardware-In-the-Loop (PHIL) real-time simulation system, which is dedicated to different hydraulic operation schemes tests and control laws validation. Then, a proper hydraulic model will be the key factor for building an efficient PHIL real-time simulation system. This work introduces a practical and generalised modelling hydraulic modelling approach, which is based on `Hill Charts’ measurements provided by industrial manufacturers. The hydraulic static model is analytically obtained by using mathematical optimization routines. In addition, the nonlinear dynamic model of the guide vane actuator is introduced in order to evaluate the effects of the induced dynamics on the electric control performances. Moreover, the reduced-scale models adapted to different laboratory conditions can be established by applying scaling laws. The suggested modelling approach enables the features of decent accuracy, light computational complexity, high flexibility and wide applications for their implementations on PHIL real-time simulations. Finally, a grid-connected energy conversion chain of bulb hydraulic turbine associated with a permanent magnet synchronous generator is chosen as an example for PHIL design and performance assessment.

“…However, only large dams were used for generation of power due to the limitations on the efficiency of small generating units. But with recent developments in the field of micro hydro units as in [21] and [22] can be sought as a future distributed generation resources. With minimum construction requirements, generation of power using microhydro turbines can vary from watts to few kilowatts as presented on website [23], which introduces a new concept of level differential hydro turbine model for micro generation.…”

Depletion of natural resources to meet power demands has revolutionized the use of Renewable Energy Sources (RESs).The paradigm shift from the centralized to distributed control is witnessed due to the Microgrids. Different configurations using smart grids and Microgrids are expected to ensure grid stability and security.Eventually, electricity market is subjected to change due to the projected changes in the grid architecture. This paper is a review on the Microgrids, its elements and the controllability. This paper discusses the major issues in the Microgrids, the factors affecting the choice of the Microgrid type and also various generation sources and their combination for reliable power quality and control. Recent developments with future trends are also addressed in this paper.
