“…The wind generation subsystem's emulation uses wind speed information, such as the presented in Figure 9(b) [58], together with (18), to feed into the grid the corresponding wind active power. This active power injection is done using a power electronics front end similar to the one described in section 4-A.…”

“…Such micro-grid architecture consists of two photovoltaic (PV) generators, one wind turbine (WT), battery storage, controllable loads and a controlled interconnection for the local low voltage grid. The battery inverter system in this micro-grid is employed to control the system voltage and frequency during isolated operation [4]. Moreover, a simulation platform is developed to simulate the steady-state and dynamic operation of low voltage three phase networks that include DG units such as WTs, fuel cells (FCs), PV systems and micro-turbines [5,6].…”

Abstract:Renewable source based micro-generations such as wind and hydro offer the best potential for emission free power in future power systems. This paper investigates the technical issues related to stable and autonomous operation of a micro-grid system consisting of renewable power sources. A small hydro generation unit and a wind farm are the main renewable power generation units in the proposed micro-grid system. The system under investigation represents a case study in Newfoundland and Labrador, Canada. The availability of the utility grid and the intermittent nature of wind power generation are taken into consideration when identifying the operational modes of the proposed micro-grid system. The investigations are carried out through dynamic modeling and simulation of the proposed micro-grid system in different operational modes. The components models of the proposed micro-grid system are also presented in this paper. The investigations reveal that appropriate control techniques are required to be developed depending upon the operational modes of the proposed system with some additional arrangements. Such arrangements include the type of energy storage unit, reactive power compensation, the management of excess power in the system due to the wind generator etc. The control concepts with additional necessities are also outlined in this paper. This paper concludes that the development of such control concepts is essential to ensure stable and automatic operation of the proposed micro-grid system while maintaining the system voltage and frequency in their rated values.

Abstract:The matrix converter or pulse width modulated frequency changer, invented in the mid-1980s, is a direct power conversion device that can generate a variable voltage and frequency from a variable input source. Industrially, it is applied in adjustable speed control of induction motor drive, power quality conditioner, and traction applications.The aim of this paper is to evaluate the steady state characteristic behavior of an induction machine in terms of its speed and torque when driven by a three phase indirect matrix converter at reduced harmonics. Similarly, projecting an AC-AC matrix converter that ensures a uniform synchronization in frequency and voltage supplies between the three phase wound rotor machine and the transformer's grid voltage supply is discussed in the Scherbius scheme. The different methods of torque calculations pertaining to some selected machine circuit diagrams are presented for comparison and analysis. Emphasis on the torque-speed characteristics of the machine at varied resistance and slip values were graphically analyzed in MATLAB to determine the degree of torque-speed dependence on the rotor resistance and slip. The overall behavior of the machine under motoring, plugging, and regenerative modes was considered in this work, while a detailed Simulink modeling of an indirect matrix converter on the Scherbius drive scheme is also presented for further analysis.
