Abstract There are dozens of studies made and ongoing related to wind integration. However, the results not easy compare. IEA WIND R&D Task 25 on ‘Design Operation Power Systems with Large Amounts Wind Power’ collects shares information generation impacts power systems, analyses guidelines methodologies. In state‐of‐the‐art report (October, 2007), final 3 years period (July, 2009) most relevant grid integration have been analysed especially regarding methodologies input data. Several...
This paper represents an expert view from Europe of future emerging technologies within the wind energy sector considering their potential, challenges, applications and technology readiness how they might evolve in coming years. These were identified as originating primarily academic sector, some start-up companies a few larger industrial entities. The following areas considered: airborne energy, offshore floating concepts, smart rotors, wind-induced harvesting devices, blade tip-mounted...
This article presents a comprehensive overview of the digital twin technology and its capability levels, with specific focus on applications in wind energy industry. It consolidates definitions levels scale from 0-5; 0-standalone, 1-descriptive, 2-diagnostic, 3-predictive, 4-prescriptive, 5-autonomous. then, an industrial perspective, identifies current state art research needs sector. is concluded that main challenges hindering realization highly capable twins fall into one four categories;...
Maximising the energy potential of offshore wind farms requires an in-depth assessment technological, economic, sociopolitical, and environmental aspects. Given large economic impact large-scale projects, a robust site selection procedure is critical for limiting financial risks while supporting informed investments. This research uncovers novel multidisciplinary approach boosting efficacy Norwegian global farm siting The proposed method uses two-stage fuzzy mathematical model that considers...
When planning and developing large-scale wind power plants in areas distant from the main transmission system, voltage control assessments reactive compensation are increasingly important. Voltage stability of regional network may be a limitation with respect to maximum rating operation plant Technical constraints relation integration weak grids general associated limited thermal capacity parts grid and/or adverse effect can have on quality stability. In certain situations, however, local...
Electricity consumption of offshore oil and gas rigs are commonly supplied by turbines located on the platforms. These expensive to operate emit significant amounts CO2 NOx. Offshore wind farms may thus be an economic environmentally sound option. This paper presents this possibility assuming a farm operated in parallel with turbines. Fuel savings emissions reductions quantified numerical simulations case study platform North Sea. It is concluded that option for supplying electricity rigs....
Installation of wind turbines may be associated with costly grid reinforcements to maintain an acceptable voltage quality. Probabilistic load flow calculation can performed by using Monte Carlo techniques for representing the uncertainty loads and speed, so that e.g. total number hours overvoltage per year estimated a distribution network several turbines. This new method makes it possible analyse disconnecting in as alternative reinforcement. Based on example is concluded connection costs...
Abstract This article gives an overview of grid integration wind farms with respect to impact on voltage quality and power system stability. The recommended procedure for assessing the turbines in distribution grids is presented. uses characteristic data determine slow variations, flicker, dips harmonics. detailed assessment allows substantially more compared previously used rule‐of‐thumb guidelines. Power stability a concern conjunction large or very weak grids. Assessment requires use...
In this paper, cable-transformer resonant overvoltages are studied on the low-voltage (LV) side of a 410-MVA generator step-up (main) transformer, due to ground fault and energization. The transformer is placed in network configuration often found Norwegian hydropower stations. calculated when systematically varying length high-voltage (HV) cable that between main LV station transformer. This multivariate analysis performed efficiently, using frequency-domain calculations inverse Numerical...
In May of 2004, the IEA Wind Implementing Agreement (IA) established R&D Task 24, “Integration and Hydropower Systems.” Australia, Canada, Finland, Norway, Sweden, Switzerland, United States joined 24 with goal collaborating in study wind integration a variety electrical system configurations (load, generation, transmission); hydro characteristics; market operational configurations. Representing these countries were utilities research organizations intent to understand potential for...
Abstract Injection of wind power into an electric grid affects the voltage quality. As quality must be within certain limits to comply with utility requirements, effect should assessed prior installation. To assess effect, knowledge about electrical characteristics turbines is needed or else result could easily inappropriate design connection. The are manufacturer‐specific but not site‐specific. This means that, having actual parameter values for a specific turbine, expected impact turbine...
Abstract Concepts for control of wind farms (WFs) can be clustered into two distinct concepts, namely, power plant (WPPC) and farm flow (WFFC). WPPC is concerned with the connection to system, compliance grid codes, provision system services. This comprises traditional way operating a WF without consideration aerodynamic turbine interaction. However, phenomena like wake effects have large impact on overall performance WF. WFFC considers such in operation. It viewed as new feature that shall...
Abstract This paper provides an overview of major transmission planning activities related to wind integration studies in the United States and Europe. Transmission for energy resources is different from capacity resources. Those differences are explained, illustrated with examples several regions becoming iterative process consisting generation expansion planning, economic‐based system reliability analysis, studies. A brief look at policy environment which this activity taking place...
