“…EFL works by 'removing' nonlinearities via nonlinear feedback, and the transformed system is independent of the operating point. The EFL method has been widely utilized for designing controllers of converters for static compensators [29], electric vehicles [30], island microgrids [31], and photovoltaic systems [3]. This paper proposes nonlinear controllers based on EFL that could generate the regulated input signals for driving RSC and GSC switches to alleviate SSCI.…”

Abstract:The increasing penetration of wind power in the grid has driven the integration of wind farms with power systems that are series-compensated to enhance power transfer capability and dynamic stability. This may lead to sub-synchronous control interaction (SSCI) problems in series-compensated doubly-fed induction generator (DFIG)-based wind farms. To mitigate SSCI, nonlinear controllers based on exact feedback linearization (EFL) are proposed in this paper. Before deriving the control laws, the exact feedback linearizability of the studied system is scrutinized. Frequency scanning analysis is employed to test the designed EFL controllers. Moreover, the performance of the EFL controllers is compared to that of classical proportional-integral (PI) controllers. A series-compensated 100 MW DFIG-based wind park is utilized to assess the performance of the designed controllers through the alleviation of sub-synchronous resonance. Analyses of the studied system reveal that the resistance is negative under sub-synchronous frequency conditions, whereas the reactance becomes negative at approximately 44 Hz. The designed EFL controllers effectively alleviate SSCI and result in positive reactance and resistance values within the whole sub-synchronous frequency range. The results from the frequency scanning method are also validated through the time domain simulation and the eigenvalue analysis.

“…In [50], authors presented the use of three-leg DSTATCOM for reactive power, harmonics and unbalanced load current compensation of a diesel generator set for an isolated system. A nonlinear controller design for a three-leg DSTATCOM connected to distribution system with distributed generation (DG) to regulate the voltage by reactive power compensation is reported in [51]. In [52], the self supporting voltage of dc bus is used for mitigation of current harmonics and load balancing.…”

“…The feedback linearization technique transforms a nonlinear system into a fully or partially linear system and linear control techniques can be employed to stabilize the whole system [21]- [24]. In the literature of power systems, the application of feedback linearization techniques on large-scale interconnected power systems has been considered in a decentralized manner due to the geographical separation of generators [25].…”

This paper presents a robust nonlinear distributed controller design for islanded operation of microgrids in order to maintain active and reactive power balance. In this paper, microgrids are considered as inverter-dominated networks integrated with renewable energy sources (RESs) and battery energy storage systems (BESSs), where solar photovoltaic generators act as RESs and plug-in hybrid electric vehicles as BESSs to supply power into the grid. The proposed controller is designed by using partial feedback linearization and the robustness of this control scheme is ensured by considering structured uncertainties within the RESs and BESSs. An approach for modeling the uncertainties through the satisfaction of matching conditions is also provided in this paper. The proposed distributed control scheme requires information from local and neighboring generators to communicate with each other and the communication among RESs, BESSs, and control centers is developed by using the concept of the graph theory. Finally, the performance of the proposed robust controller is demonstrated on a test microgrid and simulation results indicate the superiority of the proposed scheme under different operating conditions as compared to a linear-quadratic-regulator-based controller.
