In this paper a general two-step design procedure for robustness enhancement aimed at finding stable stabilizing (strong stabilizing) controllers for LTI systems is presented. The proposed approach attempts to deal with strong stabilization issues and recent linear robust control design techniques in a unified way.

In this paper, the control strategy for an overall microgrid is presented. The control has two main levels: (i) the droop control of the inverters, and (ii) the control of the static bypass switch, and the droop settings for the management of the power flow. Thus, a flexible microgrid is obtained to operate in either grid-connected or islanded mode. Results from line- interactive UPS inverters connected in parallel forming a microgrid are presented, showing the feasibility of the presented solution.

The 2-DOF Observer-controller configuration is based on a right coprime factorization of the plant and makes use of an observer-based feedback control scheme combined with aprefilter controller. A two-step design procedure is accomplished;first, we can design to guarantee stability robustness and some levels of performance in terms of disturbance rejection;second, we can design the prefilter controller to guarantee open-loop processing of the reference commands. The first step is carried out by solving a constrained H ∞ optimization problem using the right coprime factorization of the plant in an active way. The second step is done by assuming a Reference Model and by solving a Model Matching Problem. The design procedure is exemplified by means of the 1992 ACC Benchmark problem.

In this paper, a novel droop control scheme applied to distributed UPSs forming a microgrid is proposed. The control architecture consists of two levels of hierarchy: 1) the P/Q droop control method of every UPS unit and 2) the management of the microgrid through the control of the setpoints of the units and the intelligent switch connected to the strong grid. This second level of control let us to connect or disconnect the microgrid to the utility mains, resulting in two scenarios: grid-connected and islanding operation mode. Also, it is taken into account the seamlessly transition between both operation modes, the possibility to share power with the utility grid, and the energy management of the overall system.
