In recent times, interest in renewable energy-based Distributed Generation (DG) is increasing rapidly. These sources are connected to AC bus through inverter interface. During islanded mode, output voltage and frequency of should be properly regulated for stable operation it done by applying control action on inverter. The paper presents a strategy controlling output. It deals with active power...

Distributed generations can be divided into traditional synchronous generators and inverter interfaced distributed (IIDG) according to their different operation mode. While the fault characteristics of IIDG is from Generators, in-depth analysis on output are foundation micro grid protection. The mathematical models under P/Q V/F control strategy discussed. After simplifying its model, studied u...

with increasing the presence of microgrids (mgs) in the power systems, investigating the mg stability during transient faults is necessary. this study investigates the transient stability analysis of a mg supplied by multiple inverter interfaced distributed generations (iidgs) during fault. the transient stability of a mg is highly depends on the iidgs control strategy. a mg, simulated on matla...

This paper describes an inverter-interfaced distributed generation system that is interconnected with the electric power system. This system has two main goals: to serve customers with reliable electric power and to improve power quality. This system is interfaced through inverters because they are effective to control output voltage and current. Because DGs are interconnected with the electric...

In this paper, a new approach is proposed for voltage and current harmonics compensation in grid-connected microgrids (MGs). If sensitive loads are connected to the point of common coupling (PCC), compensation is carried out in order to reduce PCC voltage harmonics. In absence of sensitive loads at PCC, current harmonics compensation scenario is selected in order to avoid excessive injection of...
