The increased power demand, the depletion of the fossil fuel resources and the growth of the environmental pollution has led the world to think seriously of other alternative sources of energy. So renewable energy resources (RES) are being connected to the distribution systems, mostly done by using power electronic converters. A new control strategy for achieving maximum advantage from these gr...

A switch-mode rectifier (SMR) can provide adjustable and well-regulated DC output voltage from the available AC source with good line drawn power quality. Depending on the input/output voltage transfer characteristics, the schematics, the operation quadrant, and control, SMRs possess many classifications and application. Typical potential application examples include grid powered motor drives, ...

The recent trend of distributed generation leads to several issues regarding power quality and energy efficiency. To meet the increased demand of electricity services and to increase service quality the current power grid structure should be controlled in such a way that distributed generation could be easily connected to it. The various services are becoming challenging concern to elegantly in...

this paper presents a simple model predictive control (mpc) approach to control the power injection system (pis) for renewable energy applications. a dc voltage source and a single-phase inverter that is connected to the grid by an lcl filter form the pis. grid voltage is considered a disturbance for the system. for eliminating this disturbance, a modified model is proposed. it is usual to cont...

Single-phase grid tied inverter is one among types of inverters widely used in photovoltaic generation system due to the advantages they offer. This paper describes model and simulation of such inverter in operation as distributed generation in electrical power system under Islanding Phenomena. The role of current or voltage control and associated mechanism in photovoltaic inverter such as phot...

There is growing interest in renewable energy around the world. Since most renewable sources are intermittent in nature, it is a challenging task to integrate renewable energy resources into the power grid infrastructure. Distribution systems provide standby service during utility outages and when operated during peak load hours, potentially reduce energy costs. This paper presents a grid inter...

-Because of the acute shortage of conventional energy resources, renewable energy harness is gaining attention. Voltage source inverter forms the interface to feed the power from the renewable source to utility. In order to increase the modularity of the system, the use of several parallel inverters of reduced rating is preferred. An effective control strategy to maintain the amplitude and freq...
