The base source and volume of energy conversion implicating clear logistical and financial constraints and considerations. The changes in electrical energy supply in the UK over the past 30 years are interesting as they give an insight into what can be achieved in a relatively short period of time when faced with what seems an insurmountable problem. This paper reviews the supply of electrical energy in the UK and projections made in 2009 towards mid-century. It then compares these predictions with actual data from UK governmental statistics for the ten years from 2009 to 2019. Industry energy projections from 2019 to 2050 for four case study scenarios are then presented, the last case being related to a 60% market penetration of electric vehicles (EVs) by 2050. These studies are further projected to consider the case for 100% EV penetration by 2050. Finally, the role of electrical energy storage is discussed, and energy estimates proposed for both the 60 and 100% EV scenarios.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"21 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":"114013548","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}

In doing so particular attention is placed on the relationship with the wider network and this leads us to consider the use of intentional islanding as a mechanism for supporting distributed grid operation. Geographic Information System (GIS) data provided by Scottish Power Energy Networks is translated for use in power flow modelling software OpenDSS and this forms the basis for the studied MV and LV networks. The modelling approach includes simulating line capacity constraints upstream of the 33/11 kV primary transformer and then analysing the corresponding control response under a series of scenarios for two differing seasonal cases. The findings emphasise the importance of battery sizing and highlight the challenges involved in its use to displace back-up diesel generation but also to provide grid management services and facilitate intentional islanding decisions. The findings support the development of carbon intensity dynamic control as a metric to inform flexibility management decisions and control actions in rural areas for a system wide carbon benefit.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"27 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":"125222369","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}

GFL IBR converter control approach requires an important share of synchronous generation in the system to operate stably. Industry trends show more frequent conditions with fewer synchronous machines committed and higher penetration of GFL IBRs. These operating conditions pose increasing fast dynamics stability risks in the bulk system. A number of mitigations are being considered to address these concerns. One of them is “grid forming” (GFM) inverter and system technology. GFM IBRs have the potential to achieve stable voltage and frequency in grids with low or even no synchronous generation.

The general approaches of proportional dispatch require greater consideration of the constraints, because of grid expansion. This paper presents a new theoretical approach for a modified proportional dispatch method that is more advanced than the general algorithm and takes the voltage restriction for each wind farm unit into account. A linearization method for calculating the ohmic loss caused by reactive power flow under the voltage constraint is proposed as a major modification. To ensure that the proposed method can be applied to the controller in a stable manner, we design a machine learning-based look-up table operation. Along with the general proportional and even-dispatch methods, the proposed algorithm is simulated in order to verify it under reality-based wind farm conditions, by focusing on both electrical loss and voltage violation. The proposed modified method shows delivery improvements in compliance with the required voltage condition when simulated with PSCAD/EMTDC.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"19 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":"126125507","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 possible solution would be the introduction of grid forming controllers or the power electronic converters interfacing these sources.

In this paper, the controller of a proposed grid forming converter will be presented. In a small power system load and fault disturbances, balanced and unbalanced, will be applied, presenting the behaviour of the proposed grid forming converter.

However, small and medium wind turbines need to cope with the natural intermittent nature of wind speed at lower altitudes. This imposes challenges on optimally tracking the Maximum Power Point (MPP) of the turbine. Up to now, various MPPT techniques have been proposed. However, most of these algorithms have poor performances in gusty weather conditions exhibiting sudden changes in the wind speed. Conventional Tip Speed Ratio (TSR) control fails to track the MPP under these strong wind variations. Therefore, it is not able to capture the energy contained in wind gusts. To tackle this problem, this paper proposes and experimentally validates a bidirectional power flow controller, where a permanent magnet synchronous machine acts both as a generator and as a motor. The performance of the proposed bidirectional controller is validated through simulations and experimental results on a 7.5 kW wind turbine drivetrain to verify the improvements in terms of captured wind energy.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"402 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":"127322201","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}

Energy and water costs are significantly less as compared to equipment's, thereby generally ignored. However, irrigation energy costs are growing and can be worsened with diminishing water levels. This leads motivation to many farmers to reconnoitre ecological irrigation energy practices. Presently, farmsteads are converting into net electricity generators along with increased renewables penetration into the power grid; thereby involve other loads to maintain grid balance. Agriculture sector can be rationalized to operate large extents of renewable energy which provides sustainable flexibility to the power grid. In this context, demand management strategy is developed based on the present and future needs of grid, electricity consumption/generating farm equipment that supports the agricultural sector during this conversion. Optimization outcomes reveal that the strategy enables farmsteads in extending their services to the power grid consecutively unlocking new revenue options.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"51 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":"134383749","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 considered control schemes are Virtual Synchronous Machine, Distributed PLL-based and Power Synchronisation Control. These control schemes are implemented in an islanded wind turbine supplying a passive load and their performance during three-phase symmetrical faults are evaluated and compared.

Traditionally, uprating of existing lines and construction of new lines would have been common approaches to increase network capacity and reduce congestion. However, environmental, social, and technical challenges are encouraging network operators to apply measures which improve utilisation of the existing network, as part of future planning. Here, a mixed integer linear programming model is developed to integrate various alternative options, including dynamic line rating, energy storage systems and distributed static series compensation, into the network planning process. Using a multi-stage approach, co-optimised planning of these assets is studied and compared against a conventional reconductoring approach.

An efficient BMS can not only extend the battery life but also provide timely feedback of battery status information to a remote server. Since communication and energy balancing are crucial functions in BMS, it is of great significance to summarize the previous research in these fields for the improvement of BMS system structure optimisation and equalization circuits. The controller area network bus-based, wireless-based, and power line-based signal transmission schemes in BMS are reviewed in this paper. The advantages and limitations of these communication methods are summarised. Furthermore, various Li-ion battery-balancing topologies for energy storage systems are demonstrated in this article. Either employing resistors, capacitors, DC/DC converters for current shunting or using transformers for energy conversion among different cells, can achieve battery charge equalization. Moreover, the operating principles and charge balancing capability of these topologies are discussed.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"32 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132531100","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}
