“…As for a model control method, the kernel of the LQR control is to use state feedback to optimize the performance of the system [12]. It provides good robustness by minimizing a quadratic cost function [13] as well as performance index including settling time, overshoot during transient, and steadystate error, fast response speed [14], considerable tracking ability in output current of the inverter, which ensure the power factor (PF) of the output to the grid and low total harmonic distortion (THD) [15]. There are some cases that LQR control method is introduced into various fields of power electronics [13]- [17].…”

The design of Inductance–capacitor–inductance (LCL) grid-connected inverter based on linear quadratic regulation (LQR) has been studied widely, while the performance of the controller is not analyzed in these designs. In this paper, a new design method of LCL is discussed in detail. Different from the existing method parameter of the LQR controller is obtained according to the pole assignment. Besides, parameters of LCL-type filter are designed in term of the characteristics of the new closed-loop system. Further, the robustness of the system is analyzed separately. At last, various performances of the new design system are verified by simulation. The suppression ability of the system for switching harmonics is verified in the rated state and in the case of power change. The performance including better robustness and better resistance to weak grid comparison of the traditional design is also shown in this paper.

Load frequency control (LFC) is well known for balancing the load demand and frequency for a multi-area power system. Studies have proven that LFC can improve the global performance of multi-area power systems. In recent years, the increasing proportion of renewable energy, integration of EVs, and cyber-attacks have become the main challenges in LFC power systems. Different strategies have been applied in the literature for LFC power systems and the possible impacts of renewable energy, EVs, and cyber-attacks. This survey paper is devoted to the research on directions in LFC multi-area power systems. The mathematical model of recent challenges in LFC multi-area power systems is summarized and the similarities and differences of these challenges are analyzed. The uncertainty of renewable energy is a frequently noted issue in LFC power systems; however, the uncertainty that exists in controller design is often ignored. In this survey, we analyze methods for treating the uncertainty of renewable energy and controller. This survey paper introduces the most recent research on LFC and acquaints anyone interested in its development, such that the most effective strategies can be developed by the researchers.
