Large quantities of wind generation have already connected and are concentrated in the west. This creates large west to east power flows across the network under high wind conditions as the main demand centre and HVDC interconnection is located in the east. Under high wind conditions, thermal congestion issues are seen on the network. As the amount of installed wind on the system has increased, these issues have started to shift from localised issues to inter-regional congestion issues associated with the thermal limitations of key west to east power flow paths. An assessment of wind generator effectiveness in managing such inter-regional issues requires more complex analysis than for localised congestion issues. EirGrid has developed an automation tool to facilitate this analysis and to allow for an efficient look-ahead assessment of the effect of changing transmission outages and network sectionalising arrangements on thermal congestion issues associated with high wind generation. This paper outlines the methodology behind the tool and presents some analysis carried out using the tool.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131093644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A major challenge for operating a monitoring system is the processing of measurement data in an efficient and meaningful manner. The generated data sizes are considerable and require experts in the field for a detailed site evaluation. This is both time and cost intensive. One particular problem is the analysis of power quality events, such as transients, which usually occur in high numbers. The identification of the transient’s sources require a detailed analysis of the distorted waveforms and corresponding rms-measurements. The approach in this paper categorizes transients based on the similarity of features in order to link the events to a source. The transient waveforms and rms-measurements are both considered in the segmentation, feature extraction and data reduction process. A data set consisting of 3500 transients, measured at an electric vehicle-charging infrastructure, was utilized to validate the method. Results show that the method was able to categorize the samples into different types of transients, allowing the identification of the sources of the majority of disturbances.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126863221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The potential of RETs can be utilized by the utilities to meet the energy needs of over 1.1 billion people on the global note that do not have access to electrical power supply. As a result of the persistent load growth, it is imperative to plan how RETs can be strategically structured to achieve the optimal operation in the deregulated power sector. The design and planning of RETs in the open market scheme require the technical, environmental and economic analyses of the power system to be implemented. The performance assessment of the power system is carried out in this research work with the application of the HOMER application tool as a measure to optimize the key performance indicators of a microgrid system (MGS) and promote the utilization of RETs for power solutions. A renewable energy-based MGS proposed in the study consists of biogas generator, diesel generator (DG), photovoltaic (PV), battery system (BS) and electrical loads. The system is designed for rural electrification project and to satisfy the load demands of a rural community in accordance to the sustainable energy goals and policies of many international organizations.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115206510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research has shown this to be feasible for wind farms by using efficient prediction and sophisticated control systems. In some parts of the world, strict grid codes are already being implemented that require wind farms to provide ancillary services. Moreover, the primary reserve market in Europe is moving towards shorter procurement periods, providing wind farms an opportunity to more efficiently optimise their resources based on short term forecasts. As a result of these developments, it is expected that more wind farms will provide ancillary services in the near future. The provision of Frequency Containment Reserve (FCR) requires a fast regulation of the turbine power based on the changes of the grid frequency. It is expected that this will have an impact on the wake behind the wind turbine. In wind parks with a high capacity density, such as the offshore wind parks in Belgium, it is important to investigate this impact as it can affect other neighbouring turbines. This paper investigates the dynamic behaviour of the wake generated by a wind turbine providing grid frequency support with FCR.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121509575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because it has inherent two inductors at the input and output side, the Cuk inverter is able to step up/down the voltage with reduced input and output current ripples. Thus, smaller filtering capacitance, especially at the input side, can be used which increases its suitability for photovoltaic applications. For the maximum power point tracking control, the oscillating even order harmonic components should be eliminated from the inverter's input side otherwise the maximum power cannot be extracted. The inverter's input and output currents will be controlled independently using the proposed modulation scheme and hence even harmonics can be decoupled from the input side's current without adding additional circuitry. In addition, the paper presents a control scheme to generate sinusoidal output grid current while the input current is kept constant with time. The presented systems is verified using MATLAB simulations as well as an experimental prototype controlled by F28335 ezdsp.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124627264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
