“…Because of little affection of output power of PV generation on harmonic current, separate model of fundamental current and harmonic current could represent the real working condition. The harmonic current of PV generation is relevant to :Topology of PV inverter [5];Switching frequency and control algorithm of PV inverter [6];Output filter of PV generation [7];Harmonic impedance of grid [8];…”

Abstract-This paper analyzes impacts of grid-connected photovoltaic power plant on the harmonic current in the power quality aspect of distribution network, Summaries the requirement of harmonic current injecting in grid caused by photovoltaic power plant which connected in user side. Based on the DIgSILENT PowerFactory simulation platform, this paper simulates harmonic current injecting into grid in one case of grid-connected photovoltaic generation and then analyzes it by build models of photovoltaic generation and power grid belonged the user. The result illustrated that the harmonic current caused by user side grid connected photovoltaic generation injecting into grid satisfies standards requirements, the photovoltaic generation system should have 400kvar reactive power regulation capability.

“…Generally, multilevel converters can be classified in three categories [39]- [43]: neutral-point diode clamped structure, flying capacitor clamped structure, and cascaded converter cells structure. In order to get a cost-effective design, multilevel converters are mainly used in the 3 MW to 10 MW variable-speed full-scale power converter wind turbines.…”

-The electrical energy consumption continues to grow and more applications will be based on electricity in the next decades. We can expect that more 60 % of all energy consumption will be converted and used as electricity. It is a demand that production, distribution and use of electrical energy are done as efficiently as possible. Further, emerging climate changes argues to find future solutions which also are sustainable. Two major technologies will play important roles to solve parts of those future problems. One is the change the electrical power production from conventional, fossil (and short term) based energy sources to renewable energy sources. Another is to use power electronics to achieve high efficiency in power generation, transmission/distribution and utilization. This paper discuss trends of the most promising renewable energy sources, wind energy, which ,integrated with power electronics, is changing the future electrical infrastructure and also contributes steadily to non-carbon based electricity production. The paper's focus is on the power electronics technologies used in wind turbine systems.

“…So, power converters are extremely important for the operation at variable speed [13]. Better power quality waveform [26], decreasing of THD [27], is possible by the increase on the number of voltage levels on the power converter. Also, this increase allows for a reduction of the voltage on the insulated gate bipolar transistors (IGBTs).…”

Blade pitch control malfunction simulation in a wind energy conversion system with MPC five-level converter

This paper is on a wind energy conversion system simulation of a transient analysis due to a blade pitch control malfunction. The aim of the transient analysis is the study of the behavior of a back-to-back multiple point clamped five-level full-power converter implemented in a wind energy conversion system equipped with a permanent magnet synchronous generator. An alternate current link connects the system to the grid. The drive train is modeled by a three-mass model in order to simulate the dynamic effect of the wind on the tower. The control strategy is based on fractional-order control. Unbalance voltages in the DC-link capacitors are lessen due to the control strategy, balancing the capacitor banks voltages by a selection of the output voltage vectors. Simulation studies are carried out to evaluate not only the system behavior, but also the quality of the energy injected into the electric grid. © 2015 Elsevier Ltd.

IntroductionEnvironmental problems such as global warming and habitat preservation have to be faced by the society in nowadays in order to achieve a sustainable development. One of the causes for the global warming is said to be the increase on the level of CO 2 in the atmosphere due to fossil fuel burning [1]. However, nowadays fossil fuel burning is needed for supplying the majority of the energy demand [2]. Research and development is on the way to achieve lower pollutants emissions on conversion of energy to convenient forms of usage in order to achieve a sustainable development. Conversion of energy from renewable energy sources are in nowadays a political attractive option [3] and a wind energy conversion system (WECS) is an economically viable exploitation [4], experiencing a significant expansion [5,6]. Although, onshore WECS deployments are cheaper than offshore ones, new suitable available onshore sites for deployments are becoming scarce, particularly in Europe [7]. So, the offshore WECS is becoming a further attractive option.
