“…In the transmission level, wind turbines are firstly integrated to form a relatively large scale wind farm offshore or onshore, then they are connected to the power system through HVDC [21]- [25]. With the augmenting penetration, the grid side probably becomes a weak ac system with a low Short-Circuit Ratio (SCR) [3].…”

This paper presents an overview of researches on power system stability with high wind power penetration including analyzing methods and improvement approaches. Power system stability issues can be classified diversely according to different considerations. Each classified issue has special analyzing methods and stability improvement approaches. With increasing wind power penetration, system balancing and the reduced inertia may cause a big threaten for stable operation of power systems. To mitigate or eliminate the wind impacts for high wind penetration systems, although the practical and reliable choices currently are the strong outside connections or sufficient reserve capacity constructions, many novel theories and approaches are invented to investigate the stability issues, looking forward to an extra-high penetration or totally renewable resource based power systems. These analyzing methods and stabilization techniques are presented and discussed in this paper.

“…As the slip gets smaller, the rotor voltage decreases. The relationship to the stator emf E s can be written as [1] The current ratio is not affected by the rotor frequency and can be written as [2] The ratio of the actual rotor impedance to the stator referred rotor impedance is [3] The useful active power at the stator side can be computed as Re [4] The real power at the rotor side can be computed as…”

“…he use of high-voltage direct current voltage-sourced converters (HVDC-VSC) has been proposed for offshore power systems, including renewable energy resources [1]- [3], because these systems become more economical than alternating current systems for transmission over distances greater than 50 km in an offshore environment. Although the dynamics of the high-voltage direct current (HVDC) itself are important [4], [5], we focused our investigation on the wind turbine and plant operation.…”

This paper introduces the concept of constant volt/hertz operation of offshore wind power plants (WPPs). The deployment of offshore WPPs requires power transmission from the plant to the load center inland. Because this power transmission requires submarine cables, there is a need to use high-voltage direct current (HVDC) transmission, which is economical for distances greater than 50 km. In the concept presented here, the onshore substation was operated at 60 Hz synced with the grid, and the offshore substation was operated at variable frequency and voltage, allowing the WPP to be operated at constant volt/hertz. In this paper, a variable frequency at rated volt/hertz operation was applied to a Type 3 doubly fed induction generator (DFIG) wind turbine generator. The size of the power converter at the turbine can be significantly reduced from 30% of the rated power output in a conventional Type 3 turbine to 5% of the rated power. The DFIG allows each turbine to vary its operating speed with respect to the other turbines. Thus, small wind diversity within the WPP can be accommodated by the DFIG, and the collector system frequency can be controlled by HVDC to follow large variations in average wind speed.

“…here is currently significant interest in harnessing the vast amount of renewable wind energy available offshore [1]. However, one of the main impediments to offshore wind exploitation is the energy transmission to the load centres which are often located hundreds of kilometres away from the wind farms.…”

Abstract-This paper presents a novel hybrid modular multilevel voltage source converter suitable for grid applications. The proposed converter retains the advantages of other modular multilevel topologies and can be made more compact making it attractive for offshore stations and other footprint critical applications like city infeeds. In this paper, the basic operating principle and design criteria for the converter implementation are presented. The submodule capacitor requirements which have significant influence on the size of a converter station are also evaluated and compared to the MMC.The performance of the converter is supported by simulation results from a representative medium voltage scaled demonstrator.
