Parallel connection of multiple inverters is an important means to solve the expansion, reserve and protection distributed power generation, such as photovoltaics. In view shortcomings traditional droop control methods weak anti-interference ability, low tracking accuracy inverter output voltage serious circulation phenomenon, a finite set model predictive (FCS-MPC) strategy microgrid multi-inv...

Micro grids being a new developing technology operate in two distinct modes of operation, namely, the utility-grid-connected mode and the autonomous (or islanded) mode. In transition from the utility-grid-connected mode to the autonomous mode, the frequency of a micro grid can be seriously affected due to unbalance between power generation and power demand and at that moment, micro-sources may ...

Received Jan 30, 2017 Revised Mar 30, 2017 Accepted Apr 14, 2017 The new energy source utilization and development, gradual rise of distributed power grid miniaturization, intelligence, control has become a trend. In order to make microgrid reliable and efficiently run, control technology of microgrid has become a top priority and an inverter as microgrid basic unit, its control has become the ...

The paper proposes design of voltage source inverters for renewable energy applications such as HEV. The wind and solar are growing energy sources to world this sources to be converted alternating one for grid interfacing. Conventional inverters are electronic thyristor which has some drawbacks. To improve its efficiency and performance MOSFET based inverters using controllers has been designed...

Generally, electrics devices need alternating current. But PV generators provide direct current. So, it is necessary to use inverters. Multilevel inverters seem very suitable for this task. In this paper, we present a comparative study between three multilevel inverters: 3 levels, 5 levels and 15 levels. These inverters have the same topology and are controlled by the same law: Sinusoidal Pulse...

Multilevel inverters have several advantages over the conventional two level inverters due to their lower switching frequency, reduced switching stresses, low EMI and EMC issues, ability to achieve high voltage levels, low THD etc. Multilevel inverters can synthesize the desired voltage from several levels of DC voltages. This paper presents the comparison of three level Flying capacitor and Ca...
