“…The grid codes will also in the next years challenge the wind turbine technology which means new control concepts may still be developed. Further on -new research in the field of smart grid may even extend the demands to the wind turbine systems -they are not defined yet [2].…”

“…Now the power system is changing, as a large number of dispersed generation (DG) units, including both renewable and non-renewable sources such as wind turbines, wave generators, photovoltaic (PV) generators, small hydro, fuel cells and gas/steam powered Combined Heat and Power (CHP) stations, are being developed and installed all over the world [1]- [2]. A widespread use of renewable energy sources in distribution networks is seen.…”

-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.

Abstract:A centralized grid-connected photovoltaic (PV) station is a widely adopted method of neutral grounding using resistance, which can potentially make pre-existing protection systems invalid and threaten the safety of power grids. Therefore, studying the fault characteristics of grid-connected PV systems and their impact on power-grid protection is of great importance. Based on an analysis of the grid structure of a grid-connected PV system and of the low-voltage ride-through control characteristics of a photovoltaic power supply, this paper proposes a short-circuit calculation model and a fault-calculation method for this kind of system. With respect to the change of system parameters, particularly the resistance connected to the neutral point, and the possible impact on protective actions, this paper achieves the general rule of short-circuit current characteristics through a simulation, which provides a reference for devising protection configurations.

“…[1] Compared with traditional thermal power generation, DG has the advantages of small investment, clean environment protection, reliable power supply and flexible generation mode. [2] If configured properly, DG can effectively reduce the power loss, improve voltage quality and reduce the pollution of the environment. However, if the capacity of DG is unreasonable, or the configuration of multiple types of DG is not proper, it may result that the loss of the system increases, the voltage stability is reduced, thus affecting the safe production and operation of distribution network.…”

Abstract. The optimal planning of distributed generation which intends to maximize the capacity genetration of distributed generations (DG) is mainly studied in this paper. Firstly, the probabilistic models of wind power generation and photovoltaic power generation are established under the premise of considering the uncertainties of DGs. Secondly, on the basis of this, the DG maximum admission capacity model with the maximum capacity of the DGs as the objective function is established. The model introduces different types of constraints, including voltage level constraint, line power constraint for the traditional distribution network. In addition, in order to adapt to the active management mode, we introduce DG output constraint, OLTC tap constraint, and reactive power compensation constraint.
