Nowadays, optimal integration and utilization of renewable energy sources (RES) are of the most challenging issues in power systems. The wind and solar generation units' maximum production may or may not occur at peak consumption times resulting in non-optimal utilization of these resources. As a solution to this problem, energy storage systems (ESS) are embedded in networks. However, the power...
Sinusoidal pulse width modulation is a popular modulation for most alternating current induction motor. It only requires fewer calculations and is easy to implement. However, the shortcomings of using it are low DC voltage utilization, and poor inverter transmission capability. In recent years, there is an increasing trend and more research concentration of using space vector pulse width modula...
Renewable energy sources like wind, sun, and hydro are considered as a reliable alternative to the traditional energy sources such as oil, natural gas, or coal. This paper describes modeling and simulations to determine a method for the power performance evaluation of autonomous wind turbine system. A speed control regulator is utilized to control the DC bus voltage. The inverter gate’s signals...
The increasing penetration of renewable generators can be a significant challenge due to the fluctuation of their power generation. Energy storage (ES) units are one solution to improve power supply quality and guarantee system stability. In this paper, a hybrid microgrid is built based on photovoltaic (PV) generator and ES; and coordinated control is proposed and developed to achieve power man...
One of the most critical issues for the environment today is pollution generated by hydrocarbon combustion, which is one of the main sources of power for transportation. Hybrid electric vehicles (HEV) and full electric vehicles (EV) are rapidly advancing as alternative power trains for green transportation. The vehicles’ electrification not only involves the traction parts, but it is also gener...
According to the analysis of the common DC BUS control system about the re-winder, and based on the common DC BUS system structure analysis foundation , which has realized a set of complete re-winder drive system through the hardware disposition and the functional design, the paper describes that the system changes the model of the former drive system from the construction, and uses the seleniu...
This paper proposes a feed-forward control in a halfbridge resonant dc link inverter. The configuration of feed-forward control is based on synchronous sigma-delta modulation and the halfbridge resonant dc link inverter consists of two inductors, one capacitor and two power switches. The simulation results show the proposed technique can reject non-ideal dc bus improving the total harmonic dist...
The wind turbine based on the doubly-fed induction generator (DFIG) plays an increasingly important role in power generation. This is thanks to the benefits of these generators compared to other machines. In this paper, we present a new control strategy that limits variations and the transient overshoots in the DC bus voltage, which cause problems and sometimes leads to destruction of converter...
Contained within this paper is a discussion into the modelling and control of the electrical architecture for a HEV. Two configurations of electrical architecture are discussed; a system in which the bus voltage is allowed to vary during vehicle acceleration and regenerative braking and secondly, a fixed bus voltage system in which the voltage is held constant by the inclusion of a bi-direction...
A Space Vector Modulation Based Three-level PWM Rectifier under Simple Sliding Mode Control Strategy
In this paper, a voltage oriented control strategy for three-level PWM rectifier based on Sliding Mode Control (SMC) is introduced in order to obtain fast and accurate response of dc-bus voltage. To verify the validity of the analysis and the feasibility of the proposed control method a set of simulation tests have been conducted using Matlab/Simulink. The simulation results show that compared ...
