“…However, it is difficult to know its stability limits and to impose a transient response in case of strong external perturbations. More research on single-phase inverters with different topologies and different controllers have been published [1] [2][3] [4]. Other publications have compiled comparative performance between PID and fuzzy logic controllers and between a PI controller, a linearizing feedback and a flatness based control used in hybrid vehicle [5] [6].…”

This paper focuses on the problem of controlling a single phase DC-AC switched power converter used in Uninterruptible Power Supply (UPS). The control objective is to generate, at the system output, a sinusoidal voltage with amplitude and frequency fixed by the reference signal. To this end, three types of regulators are designed based on Backstepping technique, Sliding Mode approach and linear PID controller. A comparative study of performances of designed controllers is made by simulations in Matlab/Simulink environment.

“…iii The present study is backed by a theoretical analysis formally proving the achievement of the desired multiple objectives, whereas such analysis is missing in previous works, e.g. [14]. iv The nonlinearity of the controlled system is accounted for in the controller design and analysis, whereas it is partly or totally ignored in previous controllers [15,16].…”

We consider the problem of controlling single-phase half-bridge power converters in UPS systems operating in the presence of changing load. The control objective is twofold: (i) ensuring a satisfactory power factor correction (PFC) at the grid-UPS connection; (ii) guaranteeing a tight regulation of the DC bus voltage and the half-bridge inverter output voltage despite changes in load. The considered control problem entails several difficulties including: (i) the high dimension and strong nonlinearity of the system; (ii) the numerous state variables that are inaccessible to measurements; (iii) the uncertainty that prevails on some system parameters. The problem is dealt with using a multi-loop nonlinear adaptive control system that makes use of the backstepping design technique. The inner loop ensures the PFC objective and involves an adaptive observer estimating the grid voltage and impedance parameters. The intermediary loop regulates the inverter output voltage to its reference, which is a sinusoidal wave, and it also contains an observer estimating the current in the inverter coil. The outer loop regulates the DC bus voltage up to small size ripples. The controller performances are formally analyzed using system averaging theory.

Abstract-This project presents a solution for the design of a microgrid in Jaboneria, located in Chile considering technical and economic aspects. For the design of the microgrid, the reference time of project is 20 years and a limited budget of USD $ 250836, which is conceived as a Rural Electrification Budget. In order to produce a solution to the problem, HOMER PRO software is used. Sensitivity variables were taken into account, these include the variation of the electrical load, the state of charge of the batteries and renewable electricity generation systems. In addition other design parameters such as fuel cost, limitation residential electricity consumption, battery type, annual load profiles, fixed capital costs, etc.; were used. The cost of an Energy Management System (EMS) is not considered in the present analysis. Using HOMER, an optimal solution that combines the design parameters to find an efficient electrical energy production configuration that combines renewable energy sources (solar-wind), conventional generation (diesel) and battery power was produced, prioritizing clean energy. The optimal solution is obtained by evaluating the Net Present Value -NPC (USD $) according to each of the scenarios generated by sensitivity variables. A schematic of the system components and the corresponding load profiles are shown. Then, the information concerning renewable resources that exist in the study area and the technical-economic information of each system components was introduced. In addition, parameters of model are established. A social plan of energy-efficient consumption and citizen participation is also proposed. Finally, a simulation and analysis of the results of the scenarios generated by sensitivity variables of the system are presented. The chosen solution had the lower value of NPC and it contains the final sizing of each of the system components. This solution has to be of less value than the base budget of the project.
