For wind farms greater than 10 MW in size it is obligatory to submit four meteorological data signals: wind speed, wind direction, air temperature and air pressure. The data is collected within EirGrid and SONI and thereafter used in the wind power forecast process. The wind speed signal is the most important variable as it helps in the detection of high-speed shut down events. The importance of accurate on-site measured wind speed signals increases as a function of the installed wind capacity. Since wind farms have been installed with varying technologies over the past 20 years, the system does not have a single point of failure. The lack of uniformity has been found to be both a handling challenge and reliability strength. In order to investigate the future compatibility of the current quality of met data and to verify, whether and which types of new technology may be an acceptable source of meteorological data to be delivered to the TSOs, a study has been carried out. The study verified whether the quality of meteorological data is sufficient and reliable enough for the 2030 penetration targets set by the Irish government. This paper will describe the methods used to verify the quality of meteorological data signals, along with the various types of meteorological measurements that were found to be acceptable under varying conditions. We will also present a number of recommendations based on the findings of the study, and discuss how these recommendations are being implemented by EirGrid.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131998274","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 commercial demand side sector, considering its size (MW/MWh) and existing communication and control infrastructure, makes it a potential source of flexibility. Here, in particular, the provision of reserve from supermarket refrigeration sys-tems is presented, whereby a sufficiently large and diverse fleet of supermarkets are simulated and aggregated to system level. The all-island power system of Northern Ireland and Republic of Ireland, with a horizon of 2030, is considered as a representative study system. The impact of utilising supermarket refrigeration systems as demand response providers (as part of system scheduling), and the (maximum) rate of change of frequency following system disturbances (as part of frequency stability analysis), are investigated. Three distinct frequency control methods are provided showing that supermarkets are capable of fast frequency response services to the grid, considering their high power and energy density.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133109345","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}

However, their expected profit is potentially affected by fast fluctuations of the available wind power in real-time, which may prevent them to deliver the capacity offered at the day-ahead stage. In order to evaluate this impact, a stochastic framework aiming at maximizing the WPP's profit in the day-ahead JERM, based on hourly mean wind power forecasts, is firstly developed. Once the optimal bids are obtained, an empirical ex-post analysis is performed to assess the impact of actual wind speed fluctuations on the WPP's profit. Accordingly, the resulting revenue streams from the different market floors are separately compared to their related expected values, so as to determine the losses regarding the inability of both reserve capacity procurement and activation as well as deviations from the scheduled energy. The outcomes confirm that wind speed fluctuations have a significant impact on the WPP's ability to deliver the scheduled reserve, thus negatively impacting its actual profit.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116043869","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 proposed network model could be flexibly configured to evaluate key factors that could affect the protection performance, including the level of system strength, different control strategies adopted in the HVDC system, different levels of synchronous compensation installed at the HVDC site, etc. The developed network model contains a Modular Multilevel Converter (MMC)-based HVDC system, a NSG unit representing the converter-interfaced generation and a Synchronous Condenser (SC) representing the level of synchronous compensation. A flexible controller is designed for the HVDC system to realise various typically used control strategies, including balanced current control, constant active power control and constant reactive power control, and inject a desired level of the negative sequence current as required. The NSG employs the widely-adopted PQ control strategy. Three typical controllers, comprising the Automatic Voltage Regulator (AVR), constant reactive power and droop controller, are implemented for the SC to realistically emulate the SC behaviour under different control modes. Case studies on the application of the model for testing distance protection performance are presented. The developed model is suitable for both pure simulation-based studies and also hardware-in-the-loop test when connected to an external physical relay, thus providing an ideal testing platform for identifying the potential critical protection issues and the potential solutions in future power networks with high penetration of renewables.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117012984","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 Hardware-In-the-Loop (HIL) test setup is established to enable realistic testing of physical relays being used in the system, where simulated voltage and current waveforms are injected into the distance protection relay via an analogue amplifier, and the relay tripping signal is fed back to simulation and recorded for protection performance analysis. In the simulation, a reduced but representative transmission network model, which includes a Modular Multilevel Converter (MMC) based HVDC system, a synchronous condenser (SC), and a two-level converter representing non-synchronous generation (NSG), is developed in RSCAD for the RTDS simulator. The model can be flexibly configured to reflect different levels of system strength and synchronous compensation applied at the HVDC site. The HVDC system is implemented with a flexible controller, which can replicate typically used control strategies during faults (e.g. balanced current mode to eliminate negative sequence current, and constant active and reactive power modes to suppress the oscillations on the active and reactive power respectively), allowing the user to inject different levels of negative sequence current. From the studies, it was found that with decreased system strength, the impact of the HVDC system on the distance protection becomes apparent, i.e. protection performance could be compromised with delayed operation, and such impact, to some extent, is subject to the control strategies applied in the HVDC system. It was also observed that the installation of SC could facilitate the protection response, and such support is dependent on the SC capacity.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125413671","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 aim of this regulatory mechanism is to reduce token hoarding by consumers to better align the physical production and consumption of electricity, which in turn could decrease electrical system losses and minimise the chance of grid imbalances. To establish the effectiveness of this dayparting mechanism a market simulation is performed. This simulation is made up of 24 consumers and five producers profiles over a seven-day week. An optimisation is performed to most effectively allocate energy tokens from producers to consumers, aiming to minimise the total energy imported from the larger grid i.e. to make most effective use of local generation. Consumers are permitted to perform a measure of demand response by modulating their demand at certain points while keeping their total energy consumption constant. Allocated energy tokens can be consumed immediately, or during any subsequent daypart to the same type. A series of power flow analyses are performed using the market simulation out-turns to establish the electrical system effects. Consumers are found to move some demand to weekend days when demand is lower but generation is equally abundant. Electrical results reveal a decrease in system losses, as well as less fluctuation from the larger grid supply.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129486148","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}

Such challenges are mainly caused by the different capabilities and dynamic responses of the converters compared with synchronous machines, e.g. converters do not naturally provide inertia to the system and contribute limited fault level with very different fault characteristics. Virtual Synchronous Machines (VSMs) and Synchronous Condensers (SCs) are both considered as promising solutions to address the challenges in operating converter-dominated power systems. This paper presents comprehensive studies for evaluating and comparing the dynamic performance of VSM, SC and Synchronous Generators (SGs), under a range of grid contingency events, which include short circuit faults, frequency disturbances, voltage depression, etc. The studies aim to offer insights on the level of support VSMs can offer to the system as compared with SCs and SGs, and their advantages, potential issues and limitations that need to be considered for a wider application in the system. From the studies, it is found that the VSM can successfully ride through a voltage depression of 0.1 pu for 140 ms as part of the stability path-finder requirements of fault ride through. Furthermore, the VSM unit can have a comparable performance with SC and SG from the perspective of provision of inertial response. However, in terms of voltage step simulation, reactive power injection from the VSM is very low compared to SC and SG and the fault current characteristic of the VSM is controller depended and cannot inject high fault currents like SC and SG.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124277157","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}
