• ### Reliability assessment of a wind-power system with integrated energy storage

Publication Year: 2010, Page(s):211 - 220
Cited by:  Papers (21)
| | PDF (549 KB)

This study looks into reliability assessment and components rating of a wind-power system with integrated battery energy storage. The system can potentially be used in remote electrification projects to mitigate the reliance on diesel generators. A reliability assessment method has been proposed in this study, based on a combination of the traditional analytical and simulation-based approaches, to... View full abstract»

Linear permanent magnet (PM) machines are applicable to a number of prototype renewable energy devices and therefore are candidates for deployment. Synthetic loading for efficiency evaluation of linear PM synchronous machines is described and evaluated. Synthetic loading is a technique that eliminates the need for an external mechanical load to absorb generated shaft power during rated load effici... View full abstract»

• ### Magnitude and frequency control of grid-connected doubly fed induction generator based on synchronised model for wind power generation

Publication Year: 2010, Page(s):232 - 241
Cited by:  Papers (3)
| | PDF (729 KB)

A magnitude and frequency control (MFC) strategy has been proposed for the doubly fed induction generator (DFIG). The proposed MFC makes the DFIG equivalent to a synchronous generator in the power system. The active and reactive powers of the stator depend on the phase and magnitude of the new equivalent emf behind the internal transient reactance. The relationship between the rotor voltage and ...

• ### Efficient control scheme of wind turbines with doubly fed induction generators for low-voltage ride-through capability enhancement

Publication Year: 2010, Page(s):242 - 252

| | PDF (1028 KB)

As the penetration of wind power in electrical power systems increases, it is required that wind turbines remain connected to the grid and actively contribute to the system stability during and after grid faults. This study proposes an efficient control strategy to improve the low-voltage ride-through (LVRT) capability in doubly fed induction generators (DFIGs). The proposed scheme consists of pas...

• ### Performance analysis of salient-pole self-excited reluctance generators using a simplified model

Publication Year: 2010, Page(s):253 - 260
Cited by:  Papers (4)
| | PDF (503 KB)

A simple, direct mathematical model is developed for steady-state analysis of salient-pole, self-excited synchronous reluctance generators. The model does not require either the power consumed by the load or the ratio of the load to excitation current to be estimated which are prerequisite assumptions of previous analysis techniques. The model is verified by experiment which includes assessment of... View full abstract»

• ### Power ramp rate control and flicker mitigation for directly grid connected wind turbines

Publication Year: 2010, Page(s):261 - 271
Cited by:  Papers (12)
| | PDF (675 KB)

Power variation, voltage fluctuation and resultant flicker are critical issues related to the integration of directly grid-connected constant-speed wind turbines. This study introduces a methodology to enhance the quality of the power and voltage, and minimise the flicker produced from constant-speed direct-connected wind turbines. The method uses an electrolyser/fuel cell combination to be connec... View full abstract»

• ### Analytical modelling of partial shading and different orientation of photovoltaic modules

Publication Year: 2010, Page(s):272 - 282
Cited by:  Papers (48)
| | PDF (690 KB)

Analytical modelling of a photovoltaic (PV) power system for studying the effects of partial shading and different orientation of PV modules is presented. The proposed analytical model, although limited to the case of series PV modules and composed of complicated non-linear implicit functions, allows several important electrical characteristics of a PV system, such as I-V curve, open...

• ### Coordinated output control of multiple distributed generation schemes

Publication Year: 2010, Page(s):283 - 297
Cited by:  Papers (20)
| | PDF (520 KB)

Candidate strategies for the coordinated output control of multiple distributed generation (DG) schemes are presented. The proposed strategies are underpinned by power flow sensitivity factors and allow real-time knowledge of power system thermal ratings to be utilised. This could be of value in situations where distribution network power flows require management as a result of DG proliferation. T... View full abstract»
